Lines of Symmetry for Quadrilaterals
Explore how lines of symmetry help define different categories of quadrilaterals. Looking at a square, rectangle, trapezoid, and parallelogram, young mathematicians discover that each shape has its own, unique symmetry. Encourage your class to look for patterns between the angles and side lengths of each shape and the lines of symmetry they found.

A What? A What? A Quadrilateral
Do all quadrilaterals have right angles? Investigate attributes of these shapes with geometers, starting by finding four-sided shapes in the classroom. Learners conduct a think-pair-share search for quadrilaterals they can see then examine a bag of shapes on their desk (you'll need to prepare these ahead of time).

Create, Classify, and Sort Quadrilaterals
Quadrilaterals can be quirky! Fourth graders use geoboards and bands to create four-sided figures. They analyze the attributes such as angle size and presence of parallel sides. As a result they learn to differentiate among rectangles, squares, rhombuses, and more!
