Fractions, percentages and decimals can be hard to understand, but these reversible magnetic pieces make it so much easier by being so visual and fun to work with. Simply turn over the pieces to see that 1/4th is the same as 0.25. Line them up on the board to see that 3 of them is 3/4 etc. Use the board to fill in sections of a shape or units and use the pieces to give the right answers. Age: 4-9 (18 x 25.4 cm, Pieces: 53)
