Instructions for Use

Exploring Fractions with Shapes allows students to use concrete materials to model fractions.

To use Exploring Fractions with Shapes, click on a shape and drag it into the workspace. Select a shape by clicking on it. Once selected, the shape can be moved to any location on the workspace. Click on the tools on the top panel to select and drag, rotate, find more information about the shape, or to clear the workspace. To remove a shape, drag it to the recycling bin.

Have students find how many triangles can fit inside the hexagon. Have students manipulate other shapes to create other fractions.


Fraction Pieces allows students to use concrete materials to model fractions that are less than one.

To use Fraction Pieces, click on either the circle or square radio button to determine the shape. Click on a block button to add a piece to the workspace. Click the "Show Labels" checkbox to see the size of the fraction block being added to the workspace. Drag the block inside the outline of the whole shape and it will snap into place. Click on the block button to change the colour.

Click on the "Whole" checkboxes to show or hide the outline of the whole. These outlines show the relationship between fraction pieces and the whole. To remove a block, drag it into the trash can. To remove all the blocks, click on the "Clear" button.
