Year 1, Term 2: Shapes and objects
Scope and sequence: Perimeter, Area, Volume, Capacity, Venn diagrams
recognise, represent and classify familiar two-dimensional
shapes and three-dimensional objects.
Australian Curriculum (version 9.0)
"A student recognises, describes and represents shapes including quadrilaterals and other common polygons." (MA1-2DS-01)
"A student recognises, describes and represents familiar three-dimensional objects." (MA1-3DS-01)
"Students learn to make, compare and classify familiar shapes; recognise familiar shapes and objects in the environment, identifying the similarities and differences between them." (AC9M1SP01)
Introduction to topic
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
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:
