"A student recognises, describes
and represents shapes including quadrilaterals and other common
polygons." (MA12DS01)
"A student recognises, describes and represents familiar threedimensional objects." (MA13DS01) 
"Students learn to make, compare
and classify familiar shapes; recognise familiar shapes and

Introduction to topic
Tangram activity
An introductory geometry activity which also involved careful listening and following instructions is as follows:
Tangram activities (cont.)
Using the pieces created in the last session, create the following shapes and then draw them:

Volume
Capacity
Cylinders
Task: Give each child a piece of A4 paper and ask them to make a cylinder.
An A4 piece of paper is 210 x 297 mm. Rounding this off to centimetres would give us 21 x 30 cm. The following formula is not formally introduced until Years 7 and 8 but the teaching points are:
