Term 2, Week 8

The purpose of this activity is to support students learning to apply their knowledge of basic facts and place value to solve addition and subtraction problems with multiples of ten, such as 40 + 30 and 90 - 40.

A suggested sequence for extending the difficulty of the additions is:

Adding multiples of ten up to 100 (e.g. 50 + 20)
Subtracting multiples of ten within 100 (e.g. 80 – 50)
Adding multiples of ten over 100 (e.g. 70 + 50)
Subtracting multiples of ten starting over 100 (e.g. 130 - 40)
Adding and subtracting multiples of 100 (e.g. 700 + 200 and 900 – 400)
