LO: to identify regular and irregular polygons
Challenge 1: to identify and sort regular and irregular polygons
Watch the video below before completing today's task, which you can find beneath the video.
Challenge 2: to identify, describe and compare regular and irregular polygons
Watch the video below before having a go at this challenge.
Note that some questions ask you to measure angles. You can do this if you have a protractor, but if not, just think about whether the angles in the shape are all the same, are all different. You could maybe estimate the size of the angles!
Challenge 3: to explore angles in polygons
Watch the two videos below. The first teaches you about the interior angles in regular polygons. The next looks at some of the types of questions that you'll be completing for challenge 3 today.
