Teachers, save “Geo 3 - What Makes a Rectangle?” to assign it to your class.

PART 1: WHAT MAKES A RECTANGLE? Answer this problem on the Student Template, using the words from the word bank. Use words and pictures to show your answer. Check your answer in your Math Dictionary. PART 2: RECTANGLES = SQUARES? Mr Raskin says "All squares are rectangles, so all rectangles are also squares. Duh!" He is wrong, again. Use your Math dictionary, words and pictures to explain his error. Add your explanation to Seesaw. Rectangles image from Bridges Math.
