Year 1, Term 2: Shapes and objects

Focus: Classification

Scope and sequence: Perimeter, Area, Volume, Capacity, Venn diagrams

Learning intention: Students recognise, represent and classify familiar two-dimensional shapes and three-dimensional objects.

NSW Syllabus
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)

Week 1

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:

Task: Give each child a piece of A4 paper and ask them to make a cylinder. 

Q: Which configuration will produce the greatest volume?

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:

  1. Shape is a determining factor when dealing with volume and area.
  2. Mathematical formulas embody these relationships.  Knowing that there is a formula is more important in Year 1 than knowing how to use the formula.
  3. Mathematics is not just about questions but can be a way of explaining things.


There is a handy online calculator available at (
