Do you know your percentages from your pie charts? BrainBox Maths is crammed full of concepts taught in Key Stage 2 in England and Wales. Developed by a primary school teacher with 30 years teaching experience, BrainBox Maths strikes a great balance between learning and fun. The object of the game is to study a card for 10 seconds and then answer a question based on the roll of a die. If the question is answered correctly, the card is kept, and the person with the most number of cards after 5 or 10 minutes is the winner. Made from a minimum of 70% recycled material and designed in the UK, the BrainBox range is fabulous fun. Contents: 55 cards, 1 rules card, 1 sand timer, 1 die
