## Symmetry

• Year group: Year 4
• Term: Summer
• Topic: Geometry
• Duration: 1 weeks
• Keystage: KS2
• Age Range: 8 to 9 yrs
• Unit can be taught out of sequence: Y
• Week Range: 10

In this chapter, pupils identify lines of symmetry in 2D shapes and complete symmetrical shapes.

Pupils observe symmetry in a variety of contexts across the curriculum, such as art and PE. Using a variety of media, they draw symmetric patterns to become familiar with different orientations of lines of symmetry. They also recognise line symmetry in a range of diagrams, including where it does not dissect the original shape.

Additionally, pupils identify lines of symmetry in 2D shapes, even when the lines are not horizontal or vertical. And, given a line of symmetry and one half of a symmetrical figure, they complete the figure.

### Mathematics Mastery

#### Symmetry

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 symmetry.

• 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.

#### Symmetry

Enabling pupils to develop their mathematical reasoning skills through independent work is a key element of the Mathematics Mastery programme.

This activity explores the concept of symmetry.

• Pupils should complete these tasks using concrete manipulatives as part of the CPA approach
• Pupils should be encouraged to explain their working in full sentences
• These tasks may be adapted with pupils working in pairs to encourage mathematical discussion

#### Year 4 – Geometry: Position and direction – Summer week 11 – Block 6 - Introducing translation

This pack of resources covers Year 4 Geometry: position and direction week 11 of the summer term. The resources support a mastery approach to teaching mathematics. CPA (Concrete-Pictorial-Abstract) is promoted throughout therefore ensuring you have appropriate concrete resources in your classroom is recommended to make full use of the packs.

Week 4 includes worksheets and activities on:

• Describing a position
• Describing a position with coordinates
• Drawing on a grid
• Moving on a grid
• Describing a movement on a grid

I hope you find the resources useful. Feedback is very welcome.

#### Theme Park, Maths Enterprise

This is a group of resources I made (I used some ideas from other places, but I made the things myself) in order to use as many Maths related exercises with the final aim of creating their own theme park. Some of the skills covered are:
Shapes, co-ordinates, symmetry, speed, line graphs, pictograms, bar graphs, perimeter, area, percentages, tally, problem solving, survey, money, budget and time.

Enjoy!!

#### Rotational Symmetry

SSM Transformations Level 5 To be able to recognise the order of rotational symmetry of any shape. A simple animated presentation to demonstrate rotational symmetry to students

#### Symmetry investigation

Children investigate a statement: All regular 2D shapes/polygons have the same number of lines of symmetry as they do sides/edges This is the supporting powerpoint and worksheets for a bottom set Y3/4 class - children draw the shape, note the number of sides and lines of symmetry, then feedback to complete class chart during plenary. (Note: the rectangle will NOT follow the pattern, as it is classed as an irregular quadrilateral)
