Use this comprehensive deck of 20 teaching slides to introduce your Grade 4 students to line symmetry and rotational symmetry.

## Line and Rotational Symmetry Teaching Slides

This 20-slide teaching presentation is the perfect way to introduce your Grade Four students to two types of symmetry: line symmetry and rotation symmetry.

If you need a refresher, line symmetry is when a shape or pattern is reflected across a line of symmetry (or mirror line). The reflected shape will be exactly the same as the original, the same distance from the mirror line and the same size.

Rotational symmetry, however, is when a shape or pattern can be rotated on a central point and remains the same.

In viewing and participating in this teaching activity, through numerous check-in points, students will recognise and create line and rotational symmetry of shapes.

## How to Use This Symmetry Slide Deck in Your Classroom

Teacher tip: This resource is best used when explicitly instructing the whole class, or as a review for a small group. Work through the slides with students, pausing for the ‘check for understanding’ slides to ensure that the concepts taught are being understood and applied correctly by students.

## Tips for Differentiation + Scaffolding

A team of dedicated, experienced educators created this resource to support your geometry/space lessons. In addition to individual student work time, use this activity to enhance learning through maths groups, whole class lessons, or remote learning assignments.

If you have a mixture of above and below-level learners, we have a few suggestions for keeping students on track with these concepts:

### 🆘 Support Struggling Students

For students needing additional support, provide a printed copy of the slideshow for them to follow along at their desks. Encourage them to highlight important information as you go. Be sure to assist students in solving each question as needed. You may also like to provide a handheld mirror to assist with line symmetry.

### ➕ Challenge Fast Finishers

Students needing a challenge or extension could be prompted to take detailed notes in the form of an anchor chart or student brochure, to demonstrate their level of understanding. They could also work in partnership with a student who needs extra support to encourage them to build their verbal understanding and explanation of their knowledge.

### 🧑‍🏫 Group Learning

Project the slides onto a screen and work through them as a class by having students record their answers in their notebooks or mini whiteboards.

## Easily Prepare This Resource for Your Students
