These magnetic fraction squres are a great tool for teaching equivalents with fractions.  The whole is 120mm x 120mm.  Each of the twelve fractions has a different colour.  This set is very useful just to have on display to show the differences in fraction sizes and what fits into what, eg: two quarters fit on one half, etc.  The picture is only depicting one of each fraction, but obviously there is enough of each fraction to make a whole, eg; 2 halves, four quarters, and 10 tenths etc. Hope this makes some sense as it is difficult to explain.  For further information please do not hesitate to call and speak to Vicki about this product, or any of our product range for that matter.
