I can subtract 2 digit numbers and explain my strategy

I can subtract 2 digit numbers and explain my strategy."
It's the explain part that trip most of us up.   Just giving me the answer is not good enough in grade 3.  The steps must be explained so we talk about the different ways to subtract.  Use a number line, hundreds chart, decompose, round and estimate, algorithm.  This morning we practiced with a partner writing the strategies we were using to subtract.  A variety is always nice.

Reindeer are interesting animals and we continue to learn all about them and work at centres to show our work.  We used video today and added to our tree map.  Ask your child how to tell the difference between a male and female reindeer.
