Subject: English Language Arts (K), or Mathematics (K  2), or Science (K), or Technology Education (K  2) Title: What's Inside a Pumpkin?
Description: As part of a study on pumpkins, students will discover what's inside a pumpkin by observing a pumpkin, making individual booklets, and tasting baked pumpkin seeds.
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.
