The Fractions of Fractions Tool

fractions of fractions tool.

'The Fractions of Fractions Tool' provides students with a model for visualising calculations involving finding fractions of fractions.

The tool presents a 2x2 array which students can partition into fractions (halves, thirds, quarters, fifths, eighths, or tenths) both horizontally and vertically. Part of the area can then be shaded in each direction, allowing the student to see, for example, 4/3 x 3/4 as in the image above.

Feedback is provided to help students identify that the product of the two fractions chosen is the area shaded twice.
