Treefrog Treasure is a great on-line game provided by the Centre for Game Science. It could be used for pupils either as an extension task for someone who has finished other work or a support task for someone struggling with fractions.
The Centre for Game Science information:
“Treefrog Treasure is a platformer game that allows players to explore different worlds as a frog and learn fractions and numberline concepts. When certain obstacles are reached, a player must properly identify a target symbol, whole number, or fraction on a numberline to collect gems and complete the level. Hints are provided to help the player reach the correct answer when mistakes are made.”
It is great fun and helps with fractions as part of the game. Treefrog Treasure could easily be set as homework exercises for the holidays as it will take a while to work through the whole game .
