The same reasoning, a different answer format
Number Pattern uses the identical skip-counting and arithmetic-sequence reasoning as this site's Growing Sequence worksheets, but instead of leaving a blank to fill in, it shows three lettered answer options (A, B, C) and asks a child to pick the correct one. That shift from producing an answer to selecting one sounds small but changes the task in a real way — recognition and production draw on related but distinct skills, and a child who's confident writing in a missing number isn't automatically as confident picking the right one out of plausible-looking alternatives.
The two incorrect choices on this worksheet aren't arbitrary numbers — they're built from common mistakes a child genuinely makes at this stage. One distractor is typically the previous value repeated (a "forgot to add anything" answer), and the other uses a slightly wrong step size (an "added the wrong amount" answer). That means picking correctly requires actually confirming the rule against the sequence, not just choosing the number that looks roughly right — a careless glance is genuinely more likely to land on a wrong option here than on an obviously silly one.
The correct answer isn't always option A, or always in the same position across worksheets — which lettered slot holds the right answer varies from puzzle to puzzle, deliberately, so a child can't shortcut the exercise by learning a positional pattern instead of genuinely checking the sequence each time. That variation is invisible unless a child is specifically looking for it, but it's part of why working through several different numbered variants gives a more honest picture of real skill than judging from just one page.
A strategy that beats guessing
The most reliable approach is to ignore the three answer options entirely at first, work out what the next number should be independently, and only then check which lettered option matches. Looking at the options before working out the rule tempts a child into picking whichever one "looks right" rather than actually confirming it — and because the distractors are deliberately plausible, that shortcut fails more often on this worksheet than it would on an easier multiple-choice puzzle.
A specific, teachable habit worth reinforcing directly: read all three lettered options before selecting one, even after spotting what looks like the right answer in option A. Because the distractors are deliberately plausible, a child who stops reading as soon as one option looks correct sometimes misses that a later option is the genuinely better match — training the habit of scanning every choice before committing pays off well beyond this specific worksheet.
If a child seems to favor answer A (or B, or C) regardless of the actual sequence, that's worth checking directly — some children develop a habit of picking a "lucky" letter rather than genuinely evaluating each option, especially if that letter happened to be correct a few times in a row by chance. Mixing up which letter holds the correct answer is already handled automatically since every variant generates its own random arrangement, so a repeated same-letter pattern in a child's answers, rather than in the puzzles themselves, is the signal to address directly by asking them to justify that specific pick out loud.
What a wrong pick usually reveals
Choosing the "repeated value" distractor usually means a child stopped tracking the pattern and defaulted to the last number they saw. Choosing the "wrong step size" distractor usually means they noticed the numbers were increasing but didn't check by exactly how much each time. Naming which kind of mistake it was, rather than just marking it wrong, helps a child recognize the same trap the next time it shows up.
After a child picks an answer, correct or not, asking them to explain in one sentence why each of the other two options is wrong builds a habit that plain right/wrong feedback never does — actively ruling out plausible alternatives, rather than just confirming a hit. That explaining-the-rejects habit is precisely what distinguishes a confident test-taker from a lucky guesser on any future multiple-choice assessment, well beyond this specific worksheet.
Games and connections
With two children (or a parent and a child) working the same page, each person picks an answer independently and then compares before checking — disagreement is a natural, low-pressure prompt to talk through the reasoning together rather than one person simply being told they're wrong. That peer or parent-child discussion format tends to surface a specific sticking point (missed the step size, defaulted to the repeated number) faster than working alone and checking against an answer key.
A child who alternates between this worksheet and its Growing Sequence counterpart practices the identical underlying rule-finding skill from two directions — producing an answer from scratch versus selecting it among distractors — and getting comfortable with both forms matters, since real-world math and test questions show up in either shape unpredictably. Neither format alone fully prepares a child for both; working both regularly does.
Why this format matters
The number range and how close the distractors sit to the correct answer are both matched to Grade 2's level — not a flat difficulty setting reused everywhere, but a real match to what a child at this stage should be able to reason through with focused effort, not by guessing. As grade level increases elsewhere on this site, this same format returns with a wider range and closer, more convincing wrong answers, deepening the same skill rather than introducing a new one.
Distinguishing a correct answer from a close, plausible-looking wrong one is its own genuine skill, separate from generating an answer from scratch — and it's the exact skill standardized tests and later multiple-choice math problems depend on. Practicing it now, in a low-stakes worksheet format with numbers a child can actually reason through, builds a habit (verify before selecting, don't just pick what looks right) that pays off well beyond this specific puzzle type.
Because this worksheet mirrors the exact structure of a standardized multiple-choice math question — a stem, three plausible answers, one correct — regular practice with it builds general comfort with that format itself, separate from the specific number-pattern skill involved. A child who's used to reasoning carefully through plausible wrong answers here tends to approach any future multiple-choice test with the same habit, rather than treating it as an unfamiliar format under time pressure.
Because every numbered variant tests the identical underlying skill with fresh numbers, keeping a simple informal tally of how many a child gets right on the first try, session over session, gives a clearer picture of real progress than judging any single worksheet in isolation. A child who's slowly moving from needing to work out every option carefully toward confidently spotting the pattern at a glance is making exactly the progress this format is designed to build, even if any one individual page still takes real effort.
Behind the scenes, each puzzle's correct answer is calculated first from the actual sequence rule, and only then are the two distractors generated from it — one by repeating the previous number, one by applying a plausible but wrong step size — rather than three numbers being picked arbitrarily and one declared correct after the fact. That order matters: it guarantees the correct answer is always genuinely, mathematically right for the stated pattern, and that both wrong answers are realistic enough to actually test whether the rule was checked properly rather than being obviously silly filler.
Every numbered variant generates a fresh sequence and a fresh set of distractors testing the same Grade 2-level skill, so repeat practice always means a genuinely new pattern to work out rather than a memorized answer. This same format exists at other grade levels on this site too, with ranges and distractor difficulty matched to each one.
A teacher's guide to Grade 2 "Pick the Next Number" puzzles
A second grader looking at the numbers 41, 35 and 29 has to notice something that a first grader seldom meets: the numbers are going down. The step is not "add six" but "subtract six," and the next number is 23, not 47. A child who sees only the size of the numbers and jumps to "something bigger" will be caught out, and that is exactly the kind of mistake this puzzle is designed to bring into the open.
The Grade 2 Pick the Next Number puzzle has the same friendly layout as its Grade 1 cousin: three numbers, a blank and three choices. But the numbers are bigger, the steps are larger, and about one puzzle in three runs backward. This guide explains what is new at Grade 2, how the puzzles are built, what the wrong answers are designed to reveal, how to teach the mental arithmetic that makes the page flow, and how to turn a page of number patterns into a lesson in reasoning.
A Grade 2 Pick the Next Number page: three numbers, a blank, and three choices to pick from. At this level the steps can reach 12 and the sequence can run downward.
What is new at Grade 2
Compared with Grade 1, three things change.
Bigger steps. At Grade 1, the step runs from 2 to 10. At Grade 2, it can reach 12. That means a child has to be comfortable adding things like 11 and 12 to a two-digit number, which is real mental arithmetic.
Bigger numbers. Starting numbers can reach 30, so the sequences run into the forties and fifties, and a child must handle crossing tens boundaries.
Sequences that go down. About a third of the puzzles run backward, with a step that is subtracted. A descending sequence begins high enough that the fourth number never goes below zero.
As in Grade 1, half the puzzles are skip counting, in which the first number equals the step (for example 9, 18, 27), and half are general patterns, in which the sequence begins elsewhere (for example 7, 18, 29).
How a puzzle works
Every page shows three numbers in boxes, an empty dashed box, and three choices labeled A, B and C. The child works out the rule, decides which choice belongs in the blank, and marks it.
Take the sample page: 13, 21, 29. The gap is 8 each time, so the next number is 37, which is choice B. The wrong choices are 35 and 34.
Now take a descending example: 41, 35, 29. The gap is 6, but it goes down. The next is 29 minus 6, which is 23. Wrong choices might be 24, which is a near miss, or 26, which comes from using a step of 5 instead of 6.
The correct answer is placed in a random position, so a child cannot learn to favor A, B or C.
The two kinds of wrong answer
As at Grade 1, each puzzle has one correct answer and two distractors, and the distractors are carefully built.
The near miss. This answer is off by one or two from the correct one. It is the sort of answer you get from a small counting slip. In the sample, 35 is two less than 37.
The wrong step. This answer comes from using a step that is slightly off, one or two too big or too small, while keeping the right direction. In the sample, 34 is what you would get if the step were 7: 13, 20, 27, 34.
Notice that in a descending puzzle, both distractors still go down. The puzzle does not trick a child with an upward choice. Instead, it tests whether they get the size of the step right. Picking an answer that is too large is often a sign that the child worked out the step correctly but subtracted it badly.
Reading the pattern of wrong answers is a powerful assessment tool.

Direction first
The single most useful habit in this puzzle is to ask, before anything else: are the numbers getting bigger or smaller? It takes a second, and it prevents an entire class of error.
A child can use their finger to trace along the sequence, or say "up" or "down" aloud. Look at 41, 35, 29. "Forty-one to thirty-five... down." Now look for the size of the step.
For a child who tends to rush, a simple routine is:
- Direction. Up or down?
- Gap. How far from the first to the second?
- Check. Is the second gap the same?
- Apply. Add or subtract the step.
- Choose. Find it among the choices.
- Check again. Say the whole sequence aloud.
Six small steps, in the same order, every time.
Finding the gap in bigger numbers
Finding the gap between 13 and 21 is easier than between 29 and 41, because the second pair crosses a ten. At Grade 2, the steps run from 2 to 12, but the numbers themselves can be in the thirties and forties, so a few mental arithmetic strategies help.
| Task |
Strategy |
Example |
| Gap between two numbers |
Count up in jumps |
29 to 41: 1 to 30, 10 to 40, 1 to 41. That is 12. |
| Gap, using subtraction |
Subtract tens, then ones |
41 − 29 = 12 |
| Adding a step of 8 |
Add 10, take away 2 |
29 + 8 = 29 + 10 − 2 = 37 |
| Adding a step of 9 |
Add 10, take away 1 |
18 + 9 = 18 + 10 − 1 = 27 |
| Adding a step of 11 |
Add 10, add 1 |
18 + 11 = 18 + 10 + 1 = 29 |
| Adding a step of 12 |
Add 10, add 2 |
34 + 12 = 34 + 10 + 2 = 46 |
| Subtracting a step of 6 |
Take 9, add back 3 |
29 − 6 = 29 − 9 + 3 = 23 |
| Subtracting a step of 7 |
Subtract 10, add 3 |
36 − 7 = 36 − 10 + 3 = 29 |
These are the same strategies as in the Grade 2 math pages, and children who have practiced them will find that the puzzle flows smoothly.
Worked examples
Here are several puzzles of the kind a child will meet, with the thinking written out. The numbers are illustrations of the type, and a page may differ.

The skip counting examples (12, 24, 36, and 9, 18, 27) can be solved by recalling a multiplication table: the twelves and the nines. The general examples (7, 18, 29) cannot. A child who can do both, and who knows which kind they are looking at, is thinking flexibly.
Counting down
Descending sequences are the most interesting new feature of Grade 2, and they deserve a little attention. A child who has spent a year counting up often finds counting back difficult. A few ideas help.
- Use a number line with jumps to the left. Draw the arcs going backward.
- Use a hundred chart. Moving up a row subtracts 10. Moving left subtracts 1.
- Count back in two parts. To take 7 from 36, take 6 to reach 30, then 1 more.
- Check by going forward. If 36 minus 7 is 29, then 29 plus 7 should be 36.
- Listen for the sound. Say the sequence aloud: "fifty, forty-three, thirty-six..." Does the next number sound right?
- Connect to real life. A countdown to a rocket launch, a falling temperature, a game where you lose points.
Children who can run a sequence in both directions understand it much better, because they have seen that the step is a relationship between neighbors, not just a direction.
Skip counting and multiplication
At this level, many puzzles are skip counting by larger numbers: 6s, 7s, 8s, 9s, 11s and 12s. A child who has been practicing the multiplication table in their head will recognize these at once.
That is a feature. The puzzles reinforce the table from a different angle, as a sequence rather than a grid. A child who counts "seven, fourteen, twenty-one, twenty-eight" is saying the sevens.
But the puzzles also go beyond the table. A sequence that begins at 7 and goes up by 11 is not a multiplication fact. A child who relies on recall will not find it, and one who finds the gap will. That is the real skill.
The skip counting pages for Grade 2 and the Grade 3 multiplication pages are good companions.
A sample fifteen-minute session
A session with a seven-year-old.
- Minute 0 to 3. Warm up. Count by 6s, forward and backward. "Six, twelve, eighteen... Now back: thirty, twenty-four, eighteen..."
- Minute 3 to 5. Look at the first puzzle. "Which way are the numbers going?" Trace with a finger. "Up." Then ask for the gap.
- Minute 5 to 8. Find the gap, check the second gap, add the step. Write the number, and find it in the choices.
- Minute 8 to 10. Ask about the other two choices. "Why isn't this one right? How did someone get it?"
- Minute 10 to 13. Try a descending puzzle. Slow down, and count back on a number line.
- Minute 13 to 15. Write a puzzle for a friend. "Choose a start. Choose a step. Which way?"
The last step, making a puzzle, is the best test of understanding.
A four-week plan
A teacher or parent who wants a loose path through the Grade 2 number patterns might try the following. It is a suggestion, and any week can be repeated.
- Week 1: Skip counting fluency. Oral practice with 3s, 4s, 6s and 8s, forward and backward, on a hundred chart. One or two upward puzzles a day, mostly where the start equals the step.
- Week 2: General steps. Puzzles in which the start is not the step. Focus on finding the gap, and checking the second gap. Use the mental strategies for adding 8, 9, 11 and 12.
- Week 3: Going down. Descending sequences only. Begin with small steps on a number line, and build up. Always begin by saying "up or down?"
- Week 4: Mixed. A page with all types. Ask the child to explain each wrong choice. End the week by making puzzles for each other.
A week of short, focused sessions, with some oral work, does far more than a single long session.
Reading sequences aloud
One of the simplest and most powerful supports is to say the sequence aloud, with a steady beat. The ear catches patterns that the eye can miss.
- Say it with a rhythm. "Forty-one... thirty-five... twenty-nine... twenty-three."
- Emphasize the tens. Hearing "forty, thirty, twenty" confirms that the numbers are dropping.
- Say the step. "Down six, down six, down six."
- Say it with the answer in place. If it does not sound right, check.
- Chant it. For skip counting, a chant helps memory: "Seven, fourteen, twenty-one, twenty-eight."
A child who can hear a pattern is using more of their mind than one who is only looking.
When the start equals the step
About half the puzzles are the kind where the first number is the same as the step, such as 9, 18, 27 or 12, 24, 36. These are skip counting, and they have a special feature: the sequence is the multiplication table. 9, 18, 27 is 1 × 9, 2 × 9, 3 × 9.
This gives a child an extra route to the answer. Instead of subtracting to find the gap, they can recognize the table. The next number is 4 × 9, which is 36.
It also gives a teacher an extra tool. If a child gets skip counting puzzles right and general puzzles wrong, they are probably relying on recall rather than finding the gap. The remedy is to practice the gap-finding strategy on the general puzzles. If a child does well on general puzzles but stumbles on skip counting by 8s or 9s, the table itself needs work.
The two kinds of puzzle together give a fairly complete picture of a child's number sense.
A note on timing and pressure
These puzzles are best done slowly. There is no value in speed, and a child who is pressed will guess. A few thoughts:
- Do not time them, unless the child enjoys it.
- Allow thinking time. A pause of ten or fifteen seconds is normal.
- Value explanation over speed. "Tell me how you did it" is a better goal than "finish by three o'clock."
- Avoid comparing children. Each is on their own path.
- Stop when tired. A tired child makes careless mistakes and learns little.
- Praise the checking. "I liked how you tested the choices."
If the child enjoys a challenge, an occasional "can you beat last time?" is fine, as long as it is kept light.
Common difficulties and what helps
A child chooses a larger number in a descending puzzle. They did not check the direction. Ask, "Bigger or smaller?"
A child finds the step but adds instead of subtracting. Say aloud, "Down, so we take away."
A child makes an arithmetic slip. Practice the mental strategies, and use a number line.
A child counts numbers, not jumps. Use arcs on a number line.
A child cannot find the gap between numbers that cross a ten. Count in two parts: up to the ten, then past it.
A child is slow. That is fine. Accuracy first.
A child guesses. Ask for the reason, and check each choice.
A child is bored. Move to a harder page, or ask them to make a puzzle.
Making your own puzzles
A child who can make a number pattern puzzle understands it deeply. Here is a recipe.
- Choose a start, such as 20.
- Choose a step, such as 7.
- Choose a direction, up or down.
- Write the first three numbers: 20, 27, 34 (up), or 20, 13, 6 (down).
- Find the fourth: 41 (up). For the downward example, the fourth would be −1, which is below zero, so choose a higher start such as 41 to keep it positive.
- Write the answer, and two tempting wrong ones. A near miss (39 or 43) and a wrong step (40 or 42).
- Swap with a friend.
The point about starting high enough for a descending pattern is a nice discovery in itself. A child who realizes that "we have to start high enough so we don't go below zero" is thinking like a puzzle setter.
Games with number patterns
- The rule machine. A secret rule, such as "subtract 4." One player says a number, and the other gives the answer. After a few, guess the rule.
- Countdown. Count back from 50 by 7s, taking turns.
- Beat the sequence. One player says a number, and the next adds the step, and so on. See how far you can go.
- Sequence relay. A line of children, each saying the next number in the sequence.
- Number line hopscotch. Chalk the numbers, and hop forward and backward.
- Mystery number. "It is the fourth number in a pattern. The first three are 14, 22 and 30. What am I?"
- Pattern detective. Hide the middle number: 14, ?, 30. What is it?
A few minutes of games gives a child more practice than a page.
Connecting to the rest of the curriculum
Number patterns link to a lot of other learning.
- Skip counting and multiplication. The tables are sequences.
- Addition and subtraction. Adding and subtracting the step again and again. See the Grade 2 math pages.
- Place value. The tens digit changes, and the ones digit follows a pattern.
- Algebra. The step is a constant rate of change, which is where linear functions begin.
- Money. Counting nickels by 5s, dimes by 10s.
- Time. Counting minutes by 5s on a clock.
- Other logic puzzles. The Grade 2 growing sequence is the same idea without choices.
For teachers
A Grade 2 classroom can use these puzzles in many ways.
- Warm-ups. A sequence on the board, and the class works out the next.
- Centers. A page, a pencil and a partner.
- Early finishers. A quiet, purposeful task.
- Differentiation. Use different numbered pages for different children.
- Discussion. Ask a child to explain why a wrong choice is wrong.
- Assessment. The wrong answers show who has a slip, who has the wrong step and who missed the direction.
- Link to math. Mental addition and subtraction within 100.
For parents
You do not need to be a mathematician.
- Say the sequence aloud.
- Ask, "Up or down?"
- Ask, "How much did it change?"
- Let your child explain.
- Check the other choices. "Why not A?"
- Play in the car. "Start at 50 and count back by 5s."
Questions that come up
Is the multiple-choice format a problem? It helps. A child can test each choice against the rule, and the wrong choices show what kind of slip they made.
Why do some sequences go down? To make sure a child is looking at the direction and the rule, not just assuming that numbers grow.
My child is slow at the arithmetic. Practice the mental strategies, and use a number line. Speed will come.
What if my child finds it easy? Ask them to make puzzles, to count back from 100 by 7s, or to try Grade 3 logic.
How many puzzles a session? One to three, with discussion.
Is there a link to the Grade 1 puzzle? Yes. See the Grade 1 number pattern guide for the basics of finding the step.
A Grade 2 number pattern puzzle asks a child to find a rule, in either direction, and to check it against tempting alternatives. A child who does so with care is learning to reason, and that is more valuable than any single answer.
