## Recognising 2D and 3D shapes

• Year group: Year 1
• Term: Autumn
• Topic: Geometry
• Duration: 1 weeks
• Keystage: KS1
• Age Range: 5 to 6 yrs
• Unit can be taught out of sequence: Y
• Week Range: 9

In this chapter, pupils handle, recognise and name common 2D and 3D shapes.

Early on, pupils develop a fluency in naming 2D and 3D shapes, as well as the ability to identify them in everyday objects. They identify common 2D shapes as being rectangles, circles or triangles and recognise that a square is a special kind of rectangle. In terms of common 3D shapes, pupils are able to identify cubes, cuboids, pyramids and spheres. They use 3D shapes to understand 2D shapes, by exploring their surfaces (ie, a cube can be used to understand a square).

Pupils recognise 2D and 3D shapes in different sizes and orientations. They also know that rectangles, triangles, cuboids and pyramids are not always similar to one another. They recognise and create repeating patterns with objects and shapes.

## Resources for this topic

### White Rose Maths

#### 2D and 3D shapes

A year 1 resource for 2D and 3D shapes.

#### 2D and 3D shape

A resource for year 1 recognising 2D and 3D shapes.

### Mathematics Mastery

#### Recognising 2D and 3D shapes

Deepening pupils’ understanding of key mathematical ideas is a core element of the Mathematics Mastery programme.

Our Key Constructs highlight the essential mathematical concepts all pupils are expected to grasp within each year group, with accompanying guidance for assessing pupil progress.

Our Key Constructs are closely aligned to the National Curriculum’s objectives. We know these can be tricky to evidence, so we’ve included an example task for each concept, as well as ideas to support slower-graspers and depth tasks to challenge higher-attaining pupils.

• Pupils should work through the tasks independently
• Teachers should incorporate the CPA approach to support pupils’ learning
• Opportunities for depth and scaffolding are built into each task

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

#### Year 1 - Week 9 - Geometry - Shape

This is pack 1 of 1 on year 1 Geometry and covers the small steps:

- Recognise and name 3D shapes
- Sort 3D shapes
- Recognise and name 2D shapes
- Sort 2D shapes
- Patterns with 2D and 3D shapes

The resources aim to help children gain a deeper understanding of the concepts covered in the topic.

The resources include pictorial and abstract representations as well as reasoning and problem solving activities and more open ended problems to support and extend your whole class.

I hope you find them useful.

#### 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.

#### Tangrams

Two sets of tangrams, the first making mathematical shapes, the second making more creative pictures. Includes outlines drawn to scale to assist weaker pupils.

#### 3D shape worksheets

A selection of activities including properties, sorting etc. Also a shape story to do with children as an activity, they must listen to the story and then decide which shape you are talking about! There is also a flip chart to go with the story.

#### 2D and 3D Shape Worksheets

A selection of worksheets which can help younger children identify and describe the properties of basic 2D and 3D shapes.

#### Maths Murder Mystery 7 -Death at the sports centre

Maths murder mystery. 32 suspects. 5 clues. Each clue eliminates half the suspects. Topics covered include: drawing angles, factors, negative numbers, 3D shapes.

#### 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.

#### 3d Shape properties & nets

A printable 3d shape net worksheet for class to guess what shape it will make before building it. Differentiated 3d shape propertites questions. I used them for my level 2 class

#### Match the 2D shape descriptions to the Robots

A cut and stick activity where the children have to look at the shape of the robots heads and match the shape descriptions to each robot.

#### Geometry Revision Flashcards - 2D, 3D Shapes.

Geometry flashcards include 2D and 3D shapes, angle facts, metric units of measurement, transformations and area of triangles and quadrilaterals. You can display them on the screen or print them back to back. Every second page is the ‘answer’ or flipside to the odd numbered pages. Hope that makes sense! e.g. on one side it might show a shape and ask you to name it and on the next page it has the shape’s name.
