Subject: Mathematics (K  2), or Technology Education (K  2) Title: Stop, Look, and Find Shapes in Our School and Community!
Description: This is a projectbased lesson that provides many handson opportunities for students to learn about shapes in their environment. Students are challenged to find shapes in our world using everyday technology. Students review the characteristics of basic shapes such as squares, triangles, circles, etc. They will then learn how to use digital cameras to capture shapes in the environment and will create a digital book of their photos.
Subject: English Language Arts (K), or Mathematics (K  2) Title: What Can Shapes Be....
Description: This is a handson lesson that will help students explore shapes in their environment. Students will work in diverse groups to complete this activity. Students will make a class book of their findings.This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMSU Project.
Subject: Mathematics (K  2), or Technology Education (K  2) Title: Congruent Figures
Description: This lesson is an introduction to a unit about congruent shapes. Students will begin by listening to a book about shapes. They will then complete several handson activities, including sorting shapes, using their bodies to form congruent shapes, and using activities on the Internet to practice forming congruent shapes.
Subject: Mathematics (K  2), or Technology Education (K  2) Title: Shapes in the Classroom
Description: This lesson will teach students to identify solid figures found in the classroom and in magazines. Students will also learn more about solid figures using the Internet.
Subject: Arts Education (K), or Mathematics (K  2), or Technology Education (K  2) Title: Tantalizing Tangrams
Description: This is an introductory lesson using tangrams. Students will observe the seven geometric shapes that make up the tangram in a variety of ways that exhibit spatial relationships. They will have handson experiences using these tangrams to create new shapes. Finally, they will try to make the seven shapes form a square.

Subject: Mathematics Title: Developing Geometry Understandings and Spatial Skills through Puzzlelike Problems with Tangrams
Add Bookmark
Description: Describing figures and visualizing what they look like when they are transformed through rotations or flips or are put together or taken apart in different ways are important aspects of geometry in the lower grades. This twopart tangram example from Illuminations demonstrates the potential for highquality experiences provided by computer 'shape' environments for students as they learn concepts described in the Geometry Standard. Problemsolving tasks that involve physical manipulatives as well as virtual manipulatives afford many students an entry into mathematics that they might not otherwise experience.
