A sequenced lesson designed to scaffold and build student understanding of coordinates: plotting coordinates in all four quadrants, identifying vertices of quadrilaterals, and identifying the properties of the shape formed. Students may choose to work individually or in pairs throughout the lesson to build on their understandings. Examples of student questions and responses are provided, as well as examples of different teaching approaches, with visuals to guide the teacher to build and develop student understanding of the topic. Additionally, a prompt sheet and PowerPoint presentation have been provided.
