Each fortnight, I will put together a selection of resources designed to help cover the objectives of the new 2014 maths curriculum for secondary schools (Key Stage 3). These are all freely available from the TES website.

You can find the full collection here

I hope you find them useful

Pupils should be taught to:

**derive and illustrate properties of triangles, quadrilaterals, circles, and other plane figures [for example, equal lengths and angles] using appropriate language and technologies **

**Exploring properties of quadrilaterals**

A resource to encourage group work and discussion about identifying the properties of triangles and quadrilaterals. Comes with a worksheet for ease of planning.

A Tarsia puzzle looking at matching properties of 2D shapes to the shape names. A great way to consolidate the learning of this topic.

**Properties of quadrilaterals matching activity**

A card-sorting activity encouraging pupils to work together to match the properties of shapes to their names and diagrams.

**2D shapes properties mystery activity**

A mystery activity that gives clues about the properties of four shapes, and asks pupils to draw the shapes being described.

**identify properties of, and describe the results of, translations, rotations and reflections applied to given figures **

A worksheet with a range of questions requiring pupils to describe and carry out translations.

**Rotation using lollipop sticks**

A PowerPoint presentation based on describing and carrying out rotations using pentominoes and lollipop sticks.

**Transformations housing development activity**

A resource looking at all four transformations in a functional real-life context. Gets pupils to describe and carry out the transformations.

A reflection activity that gets pupils to reflect shapes in certain line equations, with the end result for each activity being a picture of an animal.

**describe, sketch and draw using conventional terms and notations: points, lines, parallel lines, perpendicular lines, right angles, regular polygons, and other polygons that are reflectively and rotationally symmetric **

**Rotational symmetry differentiated worksheets**

Differentiated worksheets and a presentation looking at rotational symmetry which also looks at how to find the centre of rotational symmetry.

A PowerPoint presentation looking at identifying lines of symmetry of common shapes. Nicely differentiated with opportunities for extension.

**Planes of symmetry in 3D shapes**

A PowerPoint presentation introducing planes of symmetry in 3D shapes. Includes a set of questions for pupils to attempt, along with answers.

**identify and construct congruent triangles, and construct similar shapes by enlargement, with and without coordinate grids **

**‘What can you do?’ enlargement activity**

A vast set of resources covering enlargements from basic enlargements up to more difficult scale factor enlargements on grids.

**Congruence, similarity and enlargements quiz**

Ten illustrated multiple-choice questions on congruence, similarity and enlargement, with answers.

**Enlargements and co-ordinate activity**

Activity where pupils have to perform several enlargements on a grid, which will result in a word being spelt from all the enlarged shapes.

**Enlargements – Design your own question activity**

A worksheet that allows pupils to create their own enlargement questions to give to another pupil. A great way to check for understanding.

**use the standard conventions for labelling the sides and angles of triangle ABC, and know and use the criteria for congruence of triangles **

A card-matching activity based on congruent shapes which includes some blank cards for pupils to create their own matching congruent cards

A PowerPoint-based investigation looking at creating congruent triangles from different shapes. Also includes a notebook presentation looking at congruent triangles.

**Similarity and congruence resources**

A revision PowerPoint presentation on congruency, looking at the different characteristics of congruent triangles using the ASA SAS SSS rules.
