Instructions for Use

Shape Investigator lets your child compare 2-D shapes.

To use Shape Investigator, drag and drop a shape into the play area. To rotate a shape, click on it. Shapes can be combined at the corners and snapped together. To change the colour of a shape, click a colour in the upper right palette and click on the shape in the play area. To move the picture, click the arrows on the red target icon to move up, down, right or left. Use the magnifying glasses at the bottom left to make the shapes larger or smaller. Use the red arrow to undo a move on the play area and the green arrow to redo the move. Drag any shape from the play area to delete it. Use the 'Clear' Button to start a new picture.

2-D Shapes and Symmetry helps your child use math language to describe lines of symmetry in 2-D shapes.

To use 2-D Shapes and Symmetry, read the screen, then cut and fold these paper shapes to discover if there is a pattern in the lines of symmetry. Use math language to describe the lines of symmetry in these 2-D shapes.

The Symmetrizer lets your child experiment with the symmetry in a kaleidoscope.

To use The Symmetrizer, click the 'Play" button and move the mouse over the screen. To change the design on the screen, click on the face in the centre circle. To understand the mathematics of The Symmetrizer, click the 'How?' button. Move through the reflection activities. Click the 'Next' button to continue.
