Today we are going to do some more work on our adding.
Warm Up:
Watch the video below to practise your number bonds to 10.
Can you write down the 11 different ways to make 10?
Main Task:
Copy and complete these addition sums in your jotter.
Remember when you are adding two numbers together put the big number in your pocket and add on the small number on your fingers.
When you are doing missing number sums, put the number in your pocket and count on using your fingers until you reach the answer. How many fingers did you need to use to ‘add on’?
