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!
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.
Now lets try adding together 4 numbers.
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?
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.
