# Units of Work

## Polyhedra (3D shapes)

• Units of Work
• Geometry and Measurement
• Level Three

In this unit students make and investigate a variety of three dimensional shapes, known as polyhedral (for many faces). Beginning with the Platonic solids students learn to describe polyhedral by their properties, including the number of faces, edges and vertices. The unit may culminate in students finding Euler’s famous formula.

## Solid Understanding

• Units of Work
• Geometry and Measurement
• Level Four

In this unit students make and investigate various solids, including regular and semi-regular polyhedra, and cylinders and cones. They look for patterns in the numbers of faces, edges and vertices they see whether they can “discover” Euler’s famous formula. By truncating the vertices of the Platonic solids, they find a class of semi-regular polyhedra. They also generalise how to know if arrangements of polygons will create a closed polyhedron and the common properties of nets for prisms and pyramids.

## Multiplying and dividing integers

• Units of Work
• Number and Algebra
• Level Five

This unit supports students to develop procedural fluency with multiplication and division of integers and have conceptual understanding of how integers are used in the real world.

## Integers

• Units of Work

This unit helps students to develop procedural fluency with integers and have conceptual understanding of integers in the real world.

## Transformations

• Units of Work
• Geometry and Measurement
• Level Four

Recognise when one figure is a reflection of another using variant properties such as perpendicular distance from the mirror line, equalities of lengths, areas and angles, and opposite orientation in relation to the mirror line.

Recognise the rotational symmetry of a figure including identifying the centre of rotation and the order and angle of rotation.

Create symmetrical patterns using the properties of translation, reflection and rotation.

## Building on two digit place value

• Units of Work
• Number and Algebra
• Level Two

This unit supports students learning to understand the structure of two-digit numbers and how to operate with them.

## Wildlife Counts

• Units of Work
• Statistics
• Level Four

The purpose of this unit is to engage the student in carrying out the steps of a statistical investigation in a context from the science learning area; predator control.

## Improbable sports

• Units of Work
• Number and Algebra
• Level Four

The purpose of this unit is to engage the student in applying their knowledge and skills of measurement and algebra within the science learning area; to investigate a physical system.

## Down on the farm

• Units of Work
• Number and Algebra
• Level Four

The unit is designed as a simple introduction to systems of linear equations. Students solve problems in which they meet two constraints to find a single solution. Both constraints can be expressed as linear equations.

## Solving linear equations 2

• Units of Work
• Number and Algebra
• Level Five

This unit teaches students to identify linear relationships and solve linear equations in context.
