Start by warming up your maths brain, let's practice counting forwards and backwards in 2's, 5's and 10's.

0, 2, 4, 6, 8, 10.........30, 28, 26, 24......

0, 5, 10, 15, 20.........50, 45, 40, 35, 30........

0, 10, 20, 30, 40.........100, 90, 80,, 70, 60........

Once you've warmed up your maths brain watch the video and have a go at adding two 2-digit numbers, follow the steps and have a go.
