One way to teach Quadrilaterals to 4th graders is to start by introducing the four main types of quadrilaterals: squares, rectangles, parallelograms, and trapezoids. Explain the characteristics of each type of quadrilateral and provide examples. Then, have the students identify which type of quadrilateral each example is. After that, have the students practice drawing each type of quadrilateral. Finally, have the students practice identifying and classifying different quadrilaterals.
