Description: In maths this term we have been learning about three types of strategies reversibility, rounding & compensating, equal addition and place value partitioning. We have also been having workshops for maths I am in Troy A.
Big Idea: I have mainly been working on place value & partitioning. Here is how you do it,
234 + 138 = 372
8 + 4 = 12
30 + 30 = 60
100 + 200 = 300
300 + 60 = 360 + 12 = 372
Evaluation: Next time I need to work on Place Value & Partitioning to make sure
I get the right answer every time. What strategy I have done well at is Reversibility.
FeedBack/FeedForward: i think you have worked out all of the problems well. but maybe next time you could show more working out on problems 3 and your second way of working out problem 4.
