Manipulating Platonic Solids
Online Learning No Comments »
5th graders from Ms. Scully’s class are checking out the National Library of Virtual Manipulatives. They’re finishing up their Geometry unit and are on the site to look at Platonic Solids in particular. Platonic Solids are those 3-D figures whose sides are all congruent. There are five of them. The site allows you to change their size and see the proportional changes happen in real time. You can grab any vertex and rotate the figure as well. The site allows you to make the shape transparent so you can see all edges at once.
