# Playing with 2D Shape

## Playing with 2D Shape

Giving children chance to 'play around' with two-dimensional shapes gives them the freedom to explore spatial properties for themselves, thereby developing their understanding in a meaningful way.  These activities offer contexts in which children can engage in this 'play'.

### Matching Triangles

##### Stage: 1 Challenge Level:

Can you sort these triangles into three different families and explain how you did it?

### Let's Investigate Triangles

##### Stage: 1 Challenge Level:

Vincent and Tara are making triangles with the class construction set. They have a pile of strips of different lengths. How many different triangles can they make?

### Sorting Logic Blocks

##### Stage: 1 and 2 Challenge Level:

This interactivity allows you to sort logic blocks by dragging their images.

### Transformations on a Pegboard

##### Stage: 2 Challenge Level:

How would you move the bands on the pegboard to alter these shapes?

##### Stage: 2 Challenge Level:

This practical problem challenges you to make quadrilaterals with a loop of string. You'll need some friends to help!
