round and compensating

I have been learning how to subtract using round and compensating because it helps you to caculate sums in your head. Its also easier to subtract numbers.

  3. Hi Rhaven I like the that you did a google drawing to present your math work. This problem was too hard for me to work out - so I asked my teacher and she said it's correct. We have to try to do a screencastify of our strategies. Do you? Better go, blog you later.
