Grade 1 Equal Groups: Repeated Addition to 20
Equal groups as repeated addition for grade 1, the first step toward multiplication, with every total 20 or less. Sixteen problems and an answer key.
Count the equal groups and add. Each answer is 20 or less.

What this worksheet covers
This is a 16-problem sheet — one page to work through, one page of answers to check against. What makes this set particular: the quantities stay small, which keeps the addition itself in the foreground rather than the size of the numbers. Grade 1, Operations & Algebraic Thinking, Common Core 1.OA.6: that is the exact slot this page fills.
Skills practiced
The skill underneath these problems is equal groups, arrays, and fact fluency within 100. Working the page asks a student to recall the multiplication facts quickly and accurately, without counting up to them. Fluency, not just correctness, is the target here — accurate and unhurried is the mark to aim for.
How to use this worksheet
Five focused minutes beats twenty distracted ones at this age. Fold the sheet in half, do one half today and the other tomorrow, and let the student use counters or fingers if they want them. Ask the student to re-work one missed problem from scratch rather than correcting the answer in place — the second attempt shows whether the method changed.
