Essential Understanding

The student knows that matter has physical properties and those properties determine how it is described, classified, changed, and used.

Science Background

Young Children’s Ideas About Geometric Shapes: Douglas H. Clements and Julie Sarama (PDF) - Recognizing shapes is a fundamental math and science skill. This article explains how and why children learn to identify and distinguish among different shapes.

Signature Lesson

Practice Geometry with Shape Riddles: (website) - Students work in pairs, with one giving clues to describe the properties of a shape while the other attempts to guess the name of the shape.

Supporting Lessons

Ship Shape: Utah Education Network (website) - Students create geometric figures after describing and classifying various shapes.

Elaboration Lessons and Extensions

2nd Grade Geometry Lesson Plan-Shapes: Juab School District (website) - Students describe and classify plane and solid geometric figures based on the number of sides and angles or faces, edges, and vertices.

Assessment Ideas

Provide students with a variety of common items (cereal box, baseball, etc.) and each student to describe the shape of each object, using specialized “shape” vocabulary (rectangle, cylinder, etc.) from the Signature Lesson.
