Sorting Letters

This interactivity can be used to build up children's confidence with the language associated with describing 2D shapes and their symmetrical properties.

You can use it as a teacher-led activity, for example by choosing a particular property and dragging a letter which meets that criteria to the left of the screen underneath 'These letters are in my set'. Children can then select other  letters in turn and you drag each one to the appropriate side of the screen. The group has to work out your 'rule', perhaps using as few letters as possible to test their ideas. In this way, you can use the same interactivity to highlight different properties so it can be returned to many times over the course of an academic year.
