National Library of Virtual Manipulatives The National Library of Virtual Minipulatives is a great resource for teaching math for all grade levels. The website is broken up into content area and grade level. They have manipulatives for number and operations, algebra, geometry, measurement, and data analysis/probability for grades k-12. Instead of showing students how to use a manipulative on a projector, I plan on using virtual manipulatives. Students will use a physical manipulative while I show them how to use it with the virtual manipulative. I would also like to use this resource during centers. Elementary students often get off task and sometimes abuse manipulatives (by throwing them, hitting each other, etc.) Having the students use the virtual manipulatives during centers will help them stay on task.
Geogebra Geogebra is an online math tool that has multiple different uses. I think it's a great site for focusing on geometry but it has many other uses as well! The feature I would utilize the most would be the graphing calculator and the "Geogebra Geometry". For the graphing calculator feature, I would obviously use when we were learning about graphing. I would also use this for basic math so that students would not have to provide their own graphing calculator for class. For the geometry feature, Geogebra allows students to create their own shape. I would like to use this as an "explore" for geometry. I would tell students to create a shape with... (four right angles, a polygon, a convex shape, a concave shape, etc.) Geogebra allows for the geometry section to be saved and printed. Students could print their work and I could use it as a formative assessment.
