## Making shapes

• Year group: Year 3
• Term: Summer
• Topic: Geometry
• Duration: 1 weeks
• Keystage: KS2
• Age Range: 7 to 8 yrs
• Unit can be taught out of sequence: Y
• Week Range: 8

In this chapter, pupils draw 2D shapes and make 3D shapes using modelling materials.

Pupils’ knowledge of the properties of shapes is extended include to symmetrical and non-symmetrical polygons and polyhedra. They continue to describe the properties of 2D and 3D shapes using technical vocabulary, now including that related to line lengths and angle sizes. They recognise and describe 3D shapes in different orientations.

Building on knowledge of length, weight, area and volume, pupils measure the perimeter of simple 2D shapes. They also connect decimals and rounding to the drawing and measuring straight lines in a variety of contexts.

### Mathematics Mastery

#### Making shapes

Mathematical discussion is a key element of the Mathematics Mastery programme.

Talk Tasks are a brilliant way of enabling pupils to develop their mathematical language, thinking, understanding and confidence.

This activity explores the concept of making shapes.

• Talk tasks are best completed in mixed attainment pairs, with pupils taking turns to listen and construct arguments
• Emphasis is on discussion rather than the solution, encouraging pupils to use key language and talk in full sentences
• Ask pupils to prove their answers in a variety of ways, using the CPA approach to support mathematical understanding and number sense

Like what you see? Mathematics Mastery is a professional development programme for teachers with a mission to transform mathematics education in the UK.

This task is just a taster of the complete classroom resources we offer. We also provide in-depth development training, online CPD, specialist support and assessment tools.

We believe all elements of our programme are vital in creating lasting change – enabling every child to enjoy and succeed in mathematics.

### Resources shared by teachers

#### Shape workbook

Range of shape worksheets that children have to read clues, colour different shapes and find 2d shapes in the classroom. Also 2 powerpoints that illustrate patterns and 2d shapes.

#### Maths Primary: Measuring/Shapes 'Straws 2'

Straws contains 10 activities to develop thinking skills and facts for shape at KS1, KS2 and KS3. Straws 2 adds another 4 activities, to include symmetry, perimeter and nets. Simple ideas and a great range of activities lead to real exploration of properties of 2-D shapes, and more.

#### Using a set-square to draw rectangles

A short PowerPoint I put together to help my Y5 TP group understand how to draw a rectangle properly and to use a set-square properly.

#### Chinese New Year Tangrams

A template for the children to cut out their own tangram, and a worksheet in which they need to identify the shapes used in each tangram picture.
