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.

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

January Math!
Happy New Year!! Installations of Innovation Stations continued through the winter break and more are coming online each week. Teachers who get an Innovation Station should be able to use it as soon as the installers hand them a key. However simple it may be to use, please contact your Educational Technology Facilitator (414-6553) to schedule a short training for your campus. There are a few 'Big Ideas' that we would like to pass along to teachers receiving the stations.
One of the great things about the station is the ability to use the technology in an interactive way with the class. Let's look at the 3rd Nine Weeks Math curriculum for a couple of integration ideas today.
In the 5th Grade Week 20 lessons, students are looking at area and perimeter. It used to be fun for students to go up to the overhead and draw on a transparency sheet to show perimeter or arrange small plastic squares to show area. The resulting work would be wiped away so the next student could show their answer. Using the "Exploring Area" Math template in Kidspiration3, the students are given 4 pages to show area by dragging squares. It's clear and easy. Use the wireless keyboard and mouse to let table groups show an answer as a group from their desks.
In 7th Grade, teachers can cover Geometry using Inspiration. I always valued making a large idea web with students to show prior knowledge and then continuing to edit it as we studied the content. By the end, they are very familiar with the idea web, they designed it, and it's a great study guide for a end of unit exam.
Teachers in Rockingham County, Virginia have a collection of Inspiration templates that students can use. Their geometry example (download it) encourages students to define quadrilaterals and triangles by definition and including examples from the internet. Teachers could scaffold this lesson to where students just have to add the definitions to the template or just add the picture illustrations. The end product would contain much relevant information.
In High School Geometry, Wolfram's Mathematica demonstration on similar triangles is a useful tool for students. Wolfram is really teacher-centric and offers many free online webinars for teachers to help learn effective instructional strategies to use with Wolfram resources.
If any of these ideas made you think of another way you would like to integrate tech into your instruction, always feel free to contact your Educational Technology Facilitator for more support. We'd love to hear from teachers. Let us know how you are using your Innovation Station in your classroom.
