Math Recap

LI: to recall core skills and knowledge for addition, subtraction, multiplication, fractions, and place value
We recapped what we learnt in Term 3. We recapped our learning by doing a quiz. We added & subtracted time & decimals. We also recapped on our times tables & basic facts. We also did division and grouping. We also calculated area and perimeter. There was a shape and the measurements were on there so we had to calculate it. You calculate the perimeter by adding all the sides together, and you calculate the area by multiplying the height & width. We also recapped on our fractions by sharing fractions, identifying fractions, and fractions of sets.

The strategies we used were using our basic facts. Tidy Numbers which is making the numbers to make a ten. Place Value is adding them by the place value. Repeated addition & subtraction is splitting the numbers and doing it step by step. Algorithm is also adding the numbers by Place Value. We also did rounding and compensating which is rounding the number to the nearest ten. Reversing is doing the opposite operation. For example 35 - 25 = ? So you do addition 25 + __ = 35?
