Grade 2 Equal Groups and Halving

What this worksheet covers

Sixteen story problems fill this word problems page; problem 6 asks "10 is an even number. Split it into 2 equal groups. How…", and the sheet stays at that level throughout. Every problem is set in a short situation, so the first decision is which operation it calls for and the numbers run as high as 20. Further down, problem 11 asks "Put 18 counters into 3 equal groups. How many are in each…". The sheet sits inside Common Core 2.OA.3, in the grade 2 Operations & Algebraic Thinking strand.

Skills practiced

The grade 2 mixed operations sequence covers addition and subtraction within 100 and 1,000, and three-term problems; this page sits inside it. Specifically, the problems practice grade 2 Equal Groups and Halving. Working the page asks a student to read a situation and choose an operation before computing. Eight different answers appear across the sixteen problems, so a student cannot copy one result down the page.

About the word problems format

The 16 story problems each get a full line and an answer rule; problem 6, "10 is an even number. Split it into 2 equal groups. How…" is one of them. The whole job in a mixed word problem is choosing the operation, which is exactly what a one-operation page never asks.

Set A, Set B and Set C

Set A is the original sheet, and Sets B and C were derived from it problem by problem: each number became a slot redrawn with the same shape, and every answer was recomputed exactly. Where Set A's problem 9 is "Put 12 counters into 3 equal groups. How many are in each…", Set B's is "Put 20 counters into 5 equal groups. How many are in each…".

How to use this worksheet

Grade 2 attention runs short, so split these sixteen mixed operations problems over two or three sittings rather than pushing through in one; a number line or counters within reach is a strategy, not a failure. Use the key as a check, not as a grade; none of the sixteen problems needs a score attached to be useful.
