Mind Bending Maths Problems for Transition Week

Year 4 have been buidilng their resilience in Transition Week. During Maths this week we tried to solve a problem called 'Leapfrog'.

There were some simple rules - you can slide or jump over into a space. The aim was to make the frogs and toads swop places.

With only one frog and one toad, it took 3 moves to swop them over.

We found that if there were 2 frogs and 2 toads, you needed 8 moves at least.

If there were 4 frogs and 4 toads, you needed 2 moves!


Can you find out how many moves to swop over three?


If you get stuck (we called this being 'in the pit!') here are some clues:

- never move so that you have two of the same together

- slide before you jump if possible... you need to watch where your gap goes!

You can try it at home - maybe challenge your parents or older siblings.


Can YOU master the 5 frogs and 5 toads in 35 moves?

How does it change if there are a different number - eg 3 frogs and 4 toads?
