Every sheet of 2nd grade skip counting worksheets on this page is built the moment you open it, so the 20 problems below are not the same ones the last visitor printed, and the answer key is generated with them. A typical problem from the sheet in front of you is 16, 18, 20, □, □, which works out to 22, 24; another is 18, 21, 24, □, □, giving 27, 30.
‘New set of problems’ opens the generator in its own tab. There you can change the problem count and turn the answer key on or off. ‘Print or save as PDF’ opens the print dialog — choose Save as PDF in the printer list to keep the file. The sheet fits US Letter and A4, and the answer key prints on its own page.
Sequences here start from varied points rather than always from the step size, which is what stops the exercise from becoming a recitation — see 18, 21, 24, □, □.
Skip counting is multiplication before the word is introduced. A sequence like 16, 18, 20, □, □, continued correctly to 22, 24, is the times table arriving through the front door instead of by memorisation.
Skip counting also builds the number-line sense that makes rounding and estimation feel obvious rather than rule-bound.
Counting on from an arbitrary start, as 16, 18, 20, □, □ does, is measurably harder than starting from zero, and it is the version that transfers to mental arithmetic later.
These 2nd grade skip counting worksheets are commonly aligned with the counting sequence and multiplication readiness expectations for this grade, and the skill appears in most curricula somewhere around this point.
| # | Problem | Answer | What to check |
|---|---|---|---|
| 1 | 16, 18, 20, □, □ | 22, 24 | Watch for: reversing direction |
| 2 | 18, 21, 24, □, □ | 27, 30 | Check: counting on by ones under their breath |
| 3 | 20, 25, 30, □, □ | 35, 40 | Look at: losing the pattern across a hundred boundary |
| 4 | 20, 30, 40, □, □ | 50, 60 | Ask about: restarting the sequence from zero |
| 5 | 6, 8, 10, □, □ | 12, 14 | Watch for: adding the wrong step after the first term |
| 6 | 21, 24, 27, □, □ | 30, 33 | Check: writing only one of the two missing terms |
A good first problem to do together is 16, 18, 20, □, □, which comes out at 22, 24. Do 16, 18, 20, □, □ once with the child narrating, then hand over the pencil and start the clock on the other 20 problems.
Take the first problem on the sheet as it stands, 16, 18, 20, □, □. Work 16, 18, 20, □, □ out on paper rather than in your head the first few times, say each step aloud, and check the result against 22, 24 on the key before moving on.
The key prints on its own page by default. Uncheck the answer-key box before printing if you would rather keep it back and mark the sheet yourself.
Answers appear next to their question numbers, so a wrong item like 18, 21, 24, □, □ can be found in the key in a second and re-worked while it is still fresh.
For a class set, print one sheet, press the new-worksheet button and print again. Each child gets different numbers on the same skill, so nobody can copy the answer to 16, 18, 20, □, □ from a neighbour.
Portrait orientation is what the sheet is designed for. Landscape works but wastes about a third of the paper, so leave the orientation alone unless you have a reason.
Keep the finished 2nd grade skip counting worksheets in date order — the drop in time across ten sheets is the clearest progress report you will get.
