Finding Shapes and Objects - Calculate

The focus of this activity is for students to count a variety of objects in their home environment and write the number for each.

Text

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?

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.

Sensational shape hunt

Students compare shapes. In small groups, students are taken on a 'Sensational shape hunt' outside in the school grounds. They look around, observe and describe the shapes they see in the environment. They may stop to feel the straight or curved edges, the flat or rounded sides or surfaces. They compare shapes and find ...

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.

Text

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.

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 ...

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?

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.

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 ...

reSolve: Shape: Shadows

This lesson invites students to explore the relationship between three-dimensional objects and common two-dimensional shapes. They are asked to investigate the shape of shadows cast by different three-dimensional objects. They are also asked to consider different perspectives of a single object and how the shadow shapes ...

reSolve: Statistics - Shoes

This lesson engages students in gathering and representing data on the shoes that students wear to school. Students work together as a class to sort their shoes into different categories of their choosing. They organise and represent their data using a picture graph, then use the graph to answer questions and make simple ...
