Friday

This week, we have been adding and taking away 10 from a two-digit number. Continue to practise this. Here are the steps

1. Choose a two digit number(see if you can do 15 please)

2. Add 10 

3 Work out the total. Now represent this using the part-part -whole method.

Underneath, write your two additions and then work out the inverse subtractions.

Here is an example

45+ 10=55

10+45=55

55-10=45

55-45=10
