This week you will be reviewing the key operations of addition and subtraction. 


Today, you will be looking at mental methods of addition. This means working out the answers in your head, without using written calculations or equipment (eg. cubes, dienes, your fingers). 


1. Open the PDF document below (Mental addition strategies) and read through the different strategies you can use. 

2. Log in to Mathletics.

3. Complete the assigned activities.
