Frogs and Toads

No, not bring a reptile to school day - but mathematical problem-solving in the Parera Class!


Objective:  Make the frogs and toads swap places.
Move all the green frogs so they swap places with all the brown toads.  
Use the fewest number of moves possible.

Rules:
Only one frog or toad may sit on a lilypad at any time
Only one frog or toad may move at a time
A frog or toad can only move in one direction, towards the end it is going to. No backwards moves!
A frog or toad may move in only two ways;
 o Slide onto an empty lilypad next to the one it is currently sitting on 
o Jump onto an empty lilypad over one different kind of creature; 
A frog can jump over one toad, a toad can jump over one frog.   


We have some smart thinkers in Parera Class - we managed to solve this problem with 5 frogs and 5 toads!
