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.
Standard(s): [MA2013] (2) 26: Partition circles and rectangles into two, three, or four equal shares; describe the shares using the words halves, thirds, half of, a third of, etc.; and describe the whole as two halves, three thirds, or four fourths. Recognize that equal shares of identical wholes need not have the same shape. [2G3]
Subject: Mathematics (K  2), or Technology Education (K  2)

Title: Developing Geometry Understandings and Spatial Skills through Puzzlelike Problems with Tangrams
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.
