A double sided grid. Decimals on one side and percentages and fractions on the other.
By folding the grid down the vertical channels children can discover that one quarter is the same as 25% and 0.25 etc and by folding the grids again and again they can find the equivalent fractions, percentages and decimals that make up 1. Genius.
This is for a pack of 10.
