### 2D and 3D shapes

Watch this video to learn about the features of 2D shapes. How is it different from the features of 3D shapes (solids)? Some examples of solids that incorporate 2D shapes are mentioned in this video by Sanchit - for example, a cube has six square faces. What other 3D shapes could you make that has at least one square face?

### Face painter: finding faces 1

Identify polygons on a range of prisms and polyhedra such as a cube, square pyramid or triangular prism. Picture in your head all sides of a solid. Estimate how many faces the object has. Rotate it to see all of its faces. Paint each face of a given shape such as a triangle or rectangle.

### 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.

### 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 ...

### 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?

### 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.

### Categorisation

Use this task to assess students’ knowledge and understanding of properties of shapes, and language they use when describing common features.
