This document is a pre-test and post-test for 4.NBT.4 (fluently add and subtract multi-digit whole numbers). Students will answer a series of 10 questions on each test. There are 8 multiple choice items (4 addition and 4 subtraction) and there are 2 word problems (1 addition and 1 subtraction). I used this to help plan my instruction for this standard in my classroom. Then I had students compare their pre-test and post-test and see their growth.
