Recently we have been doing lessons on different types of angles, extensively banged on about and done practical activities on right angles, and practical activities on parallel and perpendicular lines, as all of these concepts are needed to be able to classify and explain quadrilaterals. It is totally worth spending time on this topic as it really encourages maths talk. Students have to articulate their ideas using specific terminology that is new for a lot of them.
As a summary of our lesson discussions, I have made an information sheet/ knowledge organiser explaining key terminology, and names and properties of quadrilaterals, that my students can refer to. Also included are two worksheets that contain different tasks to practice identifying and classifying the shapes. Answers included.
I hope this helps some of you out!
