GOAL : use a broad range of mental strategies to solve addition and subtraction problems. This week my maths group has been learning two types of maths strategies. One of the maths strategies was tidy numbers and the other one that we learnt was place value. I have done some examples below of these. You can learn how to do both of these strategies too! Here is an example of a tidy number, 101 + 48 = 249. I know this because if you take away one from 101 then add one to 48, it would look like 100+149=249. And that is how you do it, you can try to do some examples from my create that I have done.
Comment below what have you learnt from this!
do you know how to do place value ?
