This is a real favourite in our house. Ideal for making Maths fun, played just the same as Scrabble with four main maths symbols, along with brackets in clear plastic to be placed over the top of existing numbers to make more complex formulae. Just start with simple 2+3=5 equations, and then head for fully fledged "BODMAS" rules type equations with brackets. Works well from 5/6 years upwards, and I still enjoy it as an adult. Highly recommended for having great fun with your child whilst helping maths development!! Go for it. The only reservation I have on the durability is based on the original version where you need to be careful not to overfold the board, but in all other respects, it should stand up to the normal conditions for this age group.
