### Stand up, sit down - Calculate

This game focuses on listening and matching shape properties to the correct shape, and using mathematical vocabulary to describe shapes.

### Shapes: Which One Doesn't Belong? - Calculate

The focus of this activity is to discover what students know shapes, including their features and properties. What language are students using to describe and sort shapes? How can we as teachers help students increase their shape vocabulary?

### Objects can be sorted and classified in different ways: K–2 Year A – Unit 19

This two-week unit develops student knowledge, understanding and skills with two-dimensional (2D) shapes, three-dimensional (3D) objects and volume.

### Pattern Blocks - Calculate

This activity uses pattern blocks to explore patterns and the relationship between numbers. Students use the blocks to create and describe other shapes and since the blocks are relational they can be used for other investigations. For example, turn the blocks into units – if the triangle is one what is the value of the hexagon?

### Making Shapes (Foundation lesson) - Calculate

The focus of this activity is to encourage students to check their shape to ensure/prove that it is a hexagon. Students need to develop an understanding that good mathematicians find solutions to problems, check to see if their solution is correct and explain their thinking.

### The Mathscots: Building a Cat Tower

In this animated video, Abacus the cat and Poly the puppy examine and trial different objects to build a cat tower. The mathematical focus is on making, comparing, and classifying familiar objects, using properties of faces; recognising 3-dimensional objects in the environment, and identifying the similarities and differences ...

### The Mathscots: Making Biscuit Patterns

In this animated video, Prime the puppy and Abacus the cat have fun making repeating patterns using 2 dimensional shapes. The mathematical focus is on recognising, copying, continuing and creating repeating patterns based on the attributes and properties of 2 dimensional shapes and the quantity of elements in the pattern ...

### Guess My Shape or Object - Calculate

The focus of this activity is to encourage and support students to describe two dimensional shapes and three dimensional objects according to their features or properties.

### Throw a Shape - Calculate

In this game, students throw dice to determine the number of edges and vertices of a 3D shape, they then use physical materials to build their shapes. The game gives them an opportunity to practise geometric reasoning, identifying shapes based on their properties and visualising objects in three dimensions.

### Investigating Shapes (Year 5 & 6) - Calculate

The focus of this activity is to discover what it is that students know about 2D shapes and 3D objects.

### Introduction to Shapes Year 2 - Calculate

The focus of this activity is to discover the language that students are using to describe the features of shapes. Although students may know the names of many shapes, and may know the difference between a square and a circle, the description of why these shapes are different may not be mathematically accurate. Listen to ...

### New shapes can be made by joining or partitioning existing shapes: K–2 Year A – Unit 5

New shapes can be made by joining (combining) or partitioning (breaking apart) existing shapes – exploring two-dimensional shapes' attributes and features.

### The Mathscots: Finding the Ball

In this animated video, Poly the puppy focuses on properties of two-dimensional shapes and three-dimensional objects as she plays fetch with a ball. The mathematical focus is on geometric features and describing 2D shapes and 3D objects using everyday words such as corners, edges and faces. The video includes a full transcript ...

### The Mathscots: Puppy School Obstacle Course

In this animated video, Poly the puppy makes her way through an obstacle course which features 2D shapes and 3D objects. The mathematical focus is on sorting and describing squares, circles, triangles, rectangles, spheres and cubes; recognising 2D shapes within 3D objects; understanding and using terms such as ‘first’ ...

### Teaching with videogames: Mini Melbourne - Exploring Geometry using Minecraft

In this lesson, students will explore the 'Mini Melbourne 2.0' in Minecraft to identify and locate different 3D shapes in the open world. Students will use this game as a way to explore their own world and discover how shapes, both 2D and 3D, exist in their world in many forms.

### First steps in Mathematics: Space – Diagnostic tasks

A collection of diagnostic tasks designed to use with students to assess their understanding of space-related concepts in mathematics.

### Algorithms: Year 7 – planning tool

This planning resource for Year 7 is for the topic of Algorithms. Students are introduced to the use of algorithms for sorting and classifying. They can use flow charts to do this. Algorithmic thinking is a design process and flow charts are used to show a sequence of steps and/or instructions and require decision making ...

### Work sample Year 1 Mathematics: Equilateral triangles

This work sample demonstrates evidence of student learning in relation to aspects of the achievement standards for Year 1 Mathematics. The primary purpose for the work sample is to demonstrate the standard, so the focus is on what is evident in the sample not how it was created. The sample is an authentic representation ...

### Work sample Year 2 Mathematics: Fractions

This work sample demonstrates evidence of student learning in relation to aspects of the achievement standards for Year 2 Mathematics. The primary purpose for the work sample is to demonstrate the standard, so the focus is on what is evident in the sample not how it was created. The sample is an authentic representation ...

### Work sample Foundation Year Mathematics: Sorting shapes and objects

This work sample demonstrates evidence of student learning in relation to aspects of the achievement standards for Foundation Year Mathematics. The primary purpose for the work sample is to demonstrate the standard, so the focus is on what is evident in the sample not how it was created. The sample is an authentic representation ...
