Easy Geometry Practice Using Spreadsheets

There are many ways to use manipulatives to teach geometry concepts in the classroom. The Innovation Station makes sharing these so much easier. Projecting a close-up image of a student made shape helps all students in the classroom analyze the shape to see if it meets the project criteria.

Capturing the images using the document camera will allow the teacher to use student-made geometric examples for classroom projects or visual examples that teachers could use during lesson assessments.

Texas technology assessments include assessing students on their ability to use spreadsheets. Some of those skills include formatting text, changing row and column sizes, and drawing borders. In an amazing coincidence, we can use those same tools to create 2D geometric shapes that can be printed and cut out to build 3D shapes. Spreadsheets can help students visualize the measurement of perimeter, area, and volume while also practicing technology skills at the same time.

Download this Excel document is a two-page sample that teachers can use to develop their technology-friendly geometry lesson. Lesson scaffolding ideas are included for elementary through high school students. Edit the file and make it your own!

Spreadsheets can be a valuable tool for teaching geometry concepts and the Innovation Station can help share their small examples much more easily.
