NUMBERS: The Challenge of the Week ( or Two).

We'd not yet done our numbers for today, so it should be interesting to see if weekend had any effect on this, but prior to the BH weekend we had a bit of story with bigger numbers with quite a nice ending to it.

 O really struggled with notions like 40-1, or 39 + 2.  We tried few different strategies over the course of 2 weeks with 2 weeks of holidays in-between, and finally it's definitely sinking in, it seems. Not sure if there was one strategy , that worked, but the feeling that O is trarting to firmly undestand the above concept is a really great one!
