Today we are going to recap our number bond knowledge to help us add together three or more single digit numbers.
Starter: Practise counting forwards and backwards in your 2s, 5s, and 10s. If you want a challenge try your 3s or 4s!
Task one:
So we are going to add together single digit numbers. Look at the numbers below:
3 + 5 + 7 =
What can you see? Hopefully you are all shouting out 3 and 7 make 10!! Well done, you've spotted a number bond. Now it's easy to add together...... 10 + 5 = 15.
So remember those number cards you made. You are going to use these to create some number sentences. Turn them over so you can't see what the number is.
Task two:
Now lets try adding together 4 numbers.
Task Three:
Now take your three single digit number sentence and put it into a word problem.
e.g. 4 + 6 + 2 =
Mrs Edwards had four cakes, Mrs R-J had six Chocolate fudge cakes (because she loves these!) and Mrs Nichol had two vanilla sponges. How many cakes did you teachers have altogether?
CHALLENGE:
Now can you use a two digit numbers. We're going to start with our teen numbers first.
Have a go yourself. Keep to the teens first before you take the super challenge and pick three different two digit numbers.
