HI,
Today I'm going to show you my math. In this I did Place value, Reversibility and Tidy numbers
TIDY NUMBERS:
This is a thing like 10's and 100's a tidy number needs a 0 at the end and so it becomes a number like 10. Did you know that 1450 is a tidy number?
Place value:
This is a good strategy for beginners, It is like this 456+354, you would go 400+300=700 and then 50+50=100 and then... 6+4=100 So what would this equal? 810!!!
Reversibility:
I don't think know how to explain it but I we just say this, In Reversibility you need to make a - into a + but you will see on This
What strategy would you use?
