Product Description
This worksheet provides practice using comparative relational thinking with unknowns by asking students to find the missing value in an equation with 4 numbers. For example, in 5 + 17 = 4 + ___, you know the missing number is 18 because 5, the first value, has been decreased by 1 to become 4. 17, the second value, must increase by 1 in order to keep the equation balanced. Answer key included. Created by Amber Mealey.

This worksheet can be used to assess Fourth Grade Mathematics Florida Standard MAFS.4.OA.1.b: Determine the unknown whole number in an equation relating four whole numbers using comparative relational thinking. For example, solve 76 + 9 = n + 5
for n by arguing that nine is four more than five, so the unknown number must be four greater than 76.

Update: I added a second version of the worksheet that utilizes a slightly different method for showing student work.
