Maths Challenge afternoon with Elm

This afternoon Elm class have been pushed to the limit ... the mathematical limit! With three maths challenges presented to them, the class had to work together to solve the puzzles.

The first challenge was to get one wedding cake from the first post to the third (the van). They couldn't move more than one layer or put a big piece on a smaller piece. How many moves would it take?

Next we had to use 3 pieces of string to make as many triangles across a W as possible. The maximum was 9. Could anyone work out how?

Using 4 different shapes the class ad to fit them together to make a rectangle.

Elm have definitely used their resilience muscle today!
