Scratch and the Maths challenge

My daughters do a maths challenge each week at their primary school.  I didn't pay much attention to it until my youngest was worried that she wasn't improving.  My usual criticism of these weekly quizzes is nothing is done with the information and students keep getting the same questions wrong.  In many cases, the reasons why they are getting questions wrong is never investigated.

So I had a look at the challenge and it focused on addition, subtraction and times tables.

I wrote a little application in scratch to help develop some basic numeracy and help identify where issues were occurring. I added in extra steps to assist where we found issues and practice was needed (with instant feedback).

It covers:
a) learning multiples
b) adding/subtracting to and beyond 10
c) tables (using commutative property and division)

You should be able to see it below.
