Gave my daughter some more differentiation. Tested the results with some numbers in Excel - she'd got it right. It gave her great joy to apply her school maths course to a real problem and get a result. Perhaps we should figure out a way of getting all kids to solv real problems in the maths class. It might encourage maths takeup.

I think we have a new partnership. I come up with the ideas and she figures out the maths and I program the maths. It should speed things up.
