Addition and Subtraction

Addition and Subtraction Resources

Building a wide range of addition and subtraction strategies is a crucial skill in mathematics. The addition and subtraction resources on this page provide learners with multiple ways to practise and refine their skills in this area. Some of our worksheets focus on using number lines, while others present addition and subtraction as a part-part-whole model, allowing students to see the connection between addition and subtraction. Mental computation strategies (rainbow facts, doubles, bridge to ten, etc.) help students build confidence that will assist them to work with larger, more complex problems.

Addition and Subtraction Strategies

Students need a range of strategies to work efficiently with numbers. Mental computation strategies are an important building block in mathematics. The following worksheets provide students with opportunities to understand and practise a number of these mental computation strategies.

Rainbow Facts Strategy

Rainbow Facts are number pairs that add to ten. For example: 4+6 and 8+2. Near Rainbow Facts are number pairs such as 7+4 or 5+6. Students can use their knowledge of Rainbow Facts to solve by adjusting up or down 1 as needed. A strong knowledge of these number combinations helps with faster calculation of more difficult number problems.

Doubles Strategy

Having an immediate recall of  doubles facts is very important. Doubles can also be used to aid with subtraction. For example: 14-7. Near Doubles Facts are number pairs such as 7+8 or 4+5. Students can use their knowledge of doubles to solve by adjusting up or down 1 as needed.

Counting On / Counting Back Strategy

Counting on is a very useful strategy when adding 1, 2 or 3 to a given number. Students must identify the larger number and count on to get the answer. Conversely, counting back is used when subtracting 1,2 or 3 from a given number.

Eg. 2 + 23…     24, 25.

Bridge to Ten Strategy

When adding a number close to 10 (or 100, etc), it can be useful to add as if it were 10, and adjust the answer up or down as needed.
