The simplest form of symmetry is line symmetry. But if you have a group of shapes all the same as shape G, then shape G would be congruent with all of those shapes.Ī shape can be described as symmetrical if it has a property that mathematicians refer to as symmetry. Shape G for example is not congruent with any of the other shapes in our diagram. However, it cannot be described as congruent until there is another shape to compare it to. If you look at Shape A on its own, you can say that it is an irregular hexagon and you can measure its perimeter and area. Shape A cannot be described as ‘congruent’ on its own. In the diagram below, shapes A, B, C and D are all congruent. Two shapes that are congruent have the same size and the same shape. Mathematics is full of complex terminology, but sometimes a complicated term can mean something really simple. Even matching the pattern on a roll of wallpaper involves these geometric ideas. We are faced with these ideas regularly in everyday life, in everything from product design, architecture and engineering, to occurrences in the natural world. These concepts are about how a shape’s position changes, relative to a reference, such as a line or a point. This page explores congruence, symmetry, reflection, translation and rotation. They can undergo transformations, whereby they can change position or size, or ‘aspect ratio’ (how tall and thin or short and wide they are). Plane shapes in two dimensions (drawn on a flat piece of paper for example) have measurable properties apart from just their physical measurements of side lengths, internal angles and area.

Responding and reflecting, both as artist and audience, is a fundamental part of learning in the expressive arts. – I can explore how and why creative work is made by asking questions and developing my own answers. – I have explored the concept of rotation and I am beginning to use simple fractions of a complete rotation to describe turns.Įxploring the expressive arts is essential to developing artistic skills and knowledge and it enables learners to become curious and creative individuals. – I have explored reflective symmetry in a range of contexts and I can discuss it as a property of shapes and images. – I have explored two-dimensional and three-dimensional shapes and their properties in a range of contexts. Geometry focuses on relationships involving shape, space and position, and measurement focuses on quantifying phenomena in the physical world. It is designed for CfE Level 1 / KS 1 students / National Curriculum Wales Foundation Phase Yrs 1 & 2, but can also be adapted for younger age groups. The resource can be used together as a lesson plan or as individual components to integrate into your own scheme of work. Teachers' guidance notes are included as well as activity ideas for exploring shapes. The questions and discussion suggestions are voiced directly to students, allowing the resource to be easily presented to the class. ![]() This Maths and Art and Design resource offers a series of teacher-led, whole class or group activities.
