4L2.28 Properties of 2-D shapes
Workbooks
Describe the properties of common 2-D shapes including lines of symmetry, right angles and angles.
Identify and count all the lines of symmetry for common 2-D shapes. (Remember, a circle has infinite lines of symmetry!)
10 pages
Symmetry of shapes and objects
Draw or identify a line of symmetry in a shape, object or pattern. Extend the learning by asking how many lines of symmetry can be identified.
12 pages
Identify right angles in common 2-D shapes, then on objects and finally within pictures.
23 pages
Introducing the angles 180 degrees and 360 degrees. Identify if an angle is bigger or smaller than 90 degrees and compare angles by size.
18 pages
Practise ordering angles by size, firstly as separate angles and then within a shape.
