Add and Subtract Decimals

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 practise 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 colour according to the key.

Tips for Differentiation + Scaffolding 

In addition to independent student work time, use this worksheet as an activity for:

• Guided maths groups
• Lesson warm-up
• Lesson wrap-up
• Fast finishers
• Homework assignment
• Whole-class review (via smartboard)

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

If some students need support, give them 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.
