Grade 2 Arrays and Equal Addends
Rectangular arrays and equal addends in grade 2 — count the rows, then add them. Sixteen problems on a free printable PDF with the answer key.
Find the total in each array by adding the equal rows.

What this worksheet covers
Sixteen multiplication problems fill the page, and the complete key sits behind them in the same PDF. 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 2, Operations & Algebraic Thinking, Common Core 2.OA.4: that is the exact slot this page fills.
Skills practiced
Grade 2 sits in the stretch of the multiplication progression concerned with equal groups, arrays, and fact fluency within 100. Concretely, the page tests whether a student can recall the multiplication facts quickly and accurately, without counting up to them. Consistency across the page matters more than any single answer on it.
How to use this worksheet
Sit alongside for this one. At grade 2 the useful information is not the score but which problems drew a pause, so watch for hesitation rather than waiting for the finished page. Date the sheet before filing it. A page from six weeks ago is the cheapest evidence you have that something is sticking.
