5C’s Math Work

This week in 5C, we have been doing some tricky maths work.

First, we looked at doing hard multiplication problems using partitioning. Some of them were tricky, such as 23×8, and we  even 3-digit problems, like 352×7! But we all figured them out in the end.

After break, we took a look at square numbers. We found out they were the product of a number multiplied by itself. We found square numbersw up to 144, but then it got tricky, as in  the end we were doing 18 squared minus 17 squared!
