Quadrilaterals
In this task, students will look at examples of rhombuses, rectangles, and squares to make property lists of quadrilaterals. Students will use the index card to check angles, compare side lengths and draw lines if needed. Encourage students to use “at least” when describing how many of something the shape has. For example, a rectangle has at least 4 square corners. Have students compare sides (length), and angles (square, smaller than square, larger than square).
Some students may begin to see diagonals and symmetries of the shapes. Have groups share what they discovered together (remember that defending arguments and critiquing the reasoning of others is a major part of mathematic instruction!) and create a class list for each shape.
