1.What?
Last week for maths room ten learnt how add 100 and 1000 to a number and subtract 100 and 1000.
2.Why?
I learnt that I need to use this strategy to help me add and subtract from higher numbers that are usually tricky to do.
3.How?
First you get the number say 2,546 now you look at the hundreds space and add 1 and that equals2,646 and thats how you do it.
