Quadrilaterals are so tricky! Think about it … all squares are rectangles, but not all rectangles are squares? Not to mention the fact that there are three definitions of a trapezoid! What??? Memorizing definitions is not enough for kids to fully grasp the concepts. To really understand quadrilaterals, students have to explore a variety of four-sided polygons and classify them according to their attributes.

The printables and resources in Classify It! Exploring Quadrilaterals will make it easy to engage your students in collaborative, hands-on learning experiences to learn how to classify quadrilaterals. Here’s what’s included:

• Quadrilateral Classification Pretest and Posttest
• Mini lesson with practice printable for introducing quadrilateral characteristics
• Types of Quadrilaterals mini poster, foldable and interactive notebook page
• Cooperative learning sorting activity for activating higher-level thinking and discussion
• Classify It! game for challenging students to apply newfound knowledge
• Black and white versions of all student printables
• 3 different versions based on trapezoid definitions (exclusive, inclusive, and British English)

To find out how well your students understand quadrilateral classification, administer the free Classifying Quadrilaterals pretest. This free pretest uses the “exclusive trapezoids” definition, so keep this in mind when scoring it.

If your students have difficulty with this concept, they would benefit from the activities in Classify It: Exploring Quadrilaterals. Start with the introductory lesson and then move quickly into the quadrilateral sorting activity. This activity will get your students talking about quadrilaterals in ways that will help them explore and master the concepts. It’s almost as if your students are teaching themselves!

Finally, teach your students to play Classify It! This game is a more challenging variation of the sorting activity that requires students to apply what they’ve learned about quadrilaterals as they compete for points. Students earn points for correct answers, but they lose points for incorrect answers which discourages guessing. After several rounds of the game, your students will be able to classify any quadrilateral, no matter how tricky!

Skeptical? Administer the Classifying Quadrilaterals posttest and compare the results to their pretest scores. You’ll be amazed at how much your students learn in just a matter of days!
