17 Aug 15 - number bonds

Basically the same plan as 30 Jul but with a few additions and changes.
Number bonds
Starting challenge: number bonds to 100 challenge.  Using the 100 square, get children to put numbers in to spaces that form number bonds to 100 with them (e.g. 48 goes with 52).  It would be good to do a similar thing with numbers 1 to 12 and 1 to 40 for others and may be have them switch around.

Three way split
This will be basically the same.  I'll include some adding to 100 grids as an extension.  It would be good to try some of them with the game that they take turns to put a number in the circle (1 to 9 say) and if they get more than 20 they lose.

Investigation
How many combinations with 9 or 10.  It would be good if I had some combinations hidden and they have to see if they can find it.
I need a way to maker this task more prominent so it can move on to the next activity.

Adding to 1000
Use the targets and look at the game.  This uses dice to fill a grid that should add up to 1000 or as close as possible.

I really want to introduce challenges such as Kakuro and some Subitising games but will need to see. An exploration section would be really good.

We can end with Nim or coloured countdown match with centre game.
