This week we are looking at function machines.
Function machines are just a way of asking you to carry out more than one operation. You will be given a starting number and then be given one or more operations to carry out.
e.g. 5 →x2→+1→11
This gets a little trickier when you are given the answer and need to find the starting number.
What do you think you will do here?
In this case you need to work backwards, starting at the end.
You will take your 27, subtract 2, then divide by 5
What was the starting number?
I have included a few extra activities underneath. Please don't feel under pressure to do these, however if your child is working well they can give them a go.
