Introduce the perimeter of polygons to your children using this Year 4 Perimeter of Polygons PowerPoint.
The slideshow begins by recapping what a polygon is before focussing on how we can work out the perimeter of given polygons using the measurements we know but also any other facts we know about the shape such as lines of symmetry.
Ideal for use as part of your whole-class teaching, this resource provides assessment opportunities during the lesson through the inclusion of varied fluency, reasoning and problem-solving questions.
