Quadrilateral Classification and Hierarchy Hunt

Grade 4 Mathematics Exploring Four-Sided Shapes 60-Minute Interactive Learning Adventure

What is a Quadrilateral?

A polygon with exactly 4 sides 4 vertices (corners) 4 angles Examples: squares, rectangles, diamonds

Shape Hunt Challenge!

Work in groups of 5 students Find quadrilateral cutouts around the room Discuss the properties of your shape Use yarn to outline your shape on the floor

Key Properties to Look For

Parallel lines - never meet Perpendicular lines - meet at right angles Right angles - exactly 90 degrees Equal sides - same length

The Quadrilateral Family Tree

Meet the Quadrilateral Family

{"left":"Square: 4 equal sides, 4 right angles\nRectangle: opposite sides equal, 4 right angles\nRhombus: 4 equal sides, opposite angles equal","right":"Parallelogram: opposite sides parallel and equal\nTrapezoid: exactly one pair of parallel sides\nKite: two pairs of adjacent equal sides"}

Symmetry Detective Work

Use hand mirrors to explore shapes Find lines of symmetry by folding Visit property stations around the room Match shapes to their classification criteria

Quick Check: Can You Classify?

Draw a quadrilateral with 2 pairs of parallel sides but no right angles Why is every square a rectangle, but not every rectangle a square? Name a quadrilateral with exactly one pair of parallel sides
