Friday Rich Maths Fun

Butterfly Flowers and Nim 7 from Hope School on Vimeo.

We had to pair up our butterflies so their total would be the same as one of the flowers. We became very good at using a 10 plus and other number to make a teen number.

We also played a 2 player game called Nim 7. It is a basic form of the ancient game of Nim. We needed 7 objects. We placed the 7 objects in a pile and decided who went first. (In the next game the other person went first) Each player took a turn to take away either one or two counters. The player who won was the player who took the last counter.

Some of us came up with some winning strategies.

I wonder what would happen if we started with more counters?
