Jugs

The classic problem of using two unmarked jugs to measure exactly a given quantity. The Transum version is interactive and awards a virtual trophy for each of the levels completed.

Learning the sequence of doubling numbers (powers of two) is a worthwhile pursuit for children of all ages. This game is lots of fun to play, does not require the player to already know the doubling sequence, but presents the numbers in context and in a way that will help the child learn and recognise them.

Play the game little and often! Do not spend hours and hours playing but do spend ten minutes every day working to improve your score. Your personal best score is shown at the top right of the screen and this provides a target for you to try and beat. Earn trophies as you achieve the high score tiles.

Enjoy playing the game and learning more mathematics as you do.

"We all love your starters. It is so good to have such a collection. We use them for all age groups and abilities. Have particularly enjoyed KIM's game, as we have not used that for Mathematics before. Keep up the good work and thank you very much
Best wishes from Inger Kisby"

"Excellent. Thank you very much for a fabulous set of starters. I use the 'weekenders' if the daily ones are not quite what I want. Brilliant and much appreciated."
