What I learnt on maths time!

This week I've learnt how to use tidy numbers to solve my addition and subtraction problems. Example

84 + ? = 104
Now I add 6 to 84= 90
90+ 10=100 Add 4= 104
6 + 10 + 4 = 20

Maths reflection

On Maths my group and I has been learning about place values with the help of Miss Ana. We’ve been solving problems like 64+ ? =100. We took turns showing how each person solved it by respect.

64 + 6 = 70
70 + 30 = 100
30 + 6 = 36
Answer = 36
