Adding and Subtracting with Decimals Worksheet

If your students have mastered adding and subtracting whole numbers, they are probably ready to move on to decimal computation. This worksheet will help strengthen your student’s understanding of computation with decimals.

With this worksheet, students will have practice solving decimal addition and subtraction problems using the standard algorithm. The front side of the worksheet has 6 problems for students to solve. The questions are presented horizontally, so students must understand how to line up the decimal points before properly adding or subtracting. On the back of the worksheet, students must determine if the answers to each problem are correct or incorrect, and color according to the key.

An answer key is included with your download to make grading fast and easy!  

Tips for Differentiation + Scaffolding 

For fast finishers, encourage students to order the answers from greatest to least by labeling the problems with letters. 

If there are students who need a bit of support, provide them with a number line to help with subtraction problems. Students can also complete their work on grid paper to help with proper number alignment. Additionally, this worksheet can be completed in a 1-on-1 setting or with a small group of students.
