Equivalent fractions

leave a comment »

Okay, maybe it’s late and I shouldn’t admit this; but the Illuminations Equivalent Fractions game was hard!. When I tried to do the math I’d get it wrong. When I let the picture guide me, then I got it right. I guess that is the idea. The concept is that fractions can have different denominators and number of parts, nominators, and still represent the same proportion of the whole. The game builds number sense of fractions. Students may visualize the parts to the whole and then see that the different numbers correspond to the same fraction. Errors in thinking, such as larger numbers mean larger pieces, may are be disproven with a visual representation that is then associated with the  symbolic equivalent fractions on the right. The game alow so may help children see how factors can be used to reduce fractions to the lowest common denominator. The game would build upon an understanding of fairly dividing parts of a whole, like a sheet cake. Good night.
