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:

Area - Rope activity
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:
There is a handy online calculator available at (https://www.omnicalculator.com/math/cylinder-volume).
