This set worksheets will help your students better understand the nature of sum and difference equations.

Your students will use this slew of worksheets to help them understand the use and purpose behind the various symbols we use with both addition and subtraction. Each sheet contains equations consisting of two numbers and a result, but without the operational sign. Your students must choose whether the given equation becomes correct with an addition sign or a subtraction sign. Answer keys are available for each of these activity sheets for instructors. Each set consists of multiple pages, so be sure to print all of them.

These worksheets are great for reviewing basic math operations. You can even push students further by asking them to change the symbols and make them use multiplication and or division.
