One way to teach Quadrilaterals to third graders is to use hands-on activities. For example, you could have the students create a Quadrilateral with construction paper and scissors. You could also have them draw Quadrilaterals on a piece of paper and label the sides and angles. You could also have them use manipulatives such as pattern blocks or geoboards to explore the different shapes and properties of Quadrilaterals. Additionally, you could have them play Quadrilateral-related games such as Quadrilateral Bingo or Quadrilateral Memory. Finally, you could have them complete Quadrilateral-related worksheets or puzzles.
