Subtraction Wednesday

Warm Up:

• Start from 30 and count backwards – try and write your numbers all the way to 0. Maybe you could challenge yourself and start from 100 and try and count all the way back to 0!

• Watch this video all about subtraction

Main Task:

• Write down your subtraction sums in your jotter and then answer them.

• Remember to put the big number in your pocket and count back the small number using your fingers, or use a number line, to help you.

Primary 1	Primary 2
0 – 0 =	20 – 10 =
6 – 2 =	17 – 2 =
5 – 3 =	16 – 3 =
6 – 6 =	20 – 20 =
2 – 1 =	15 – 5 =
10 – 1 =	10 – 6 =
7 – 0 =	14 – 4 =
4 – 2 =	19 – 6 =

Extra Challenge: 

• Can you tell someone all the things you know about subtraction?

• Maybe you could make a poster to teach someone how to subtract.
