The National Library of Virtual Manipulatives (NLVM) is a great resource when trying to get across sometimes hard to understand math concepts to our students. It works great on our TECs and students can use it in the labs and on laptops to help them better understand certain concepts. With resources grouped by grade level (K-12) and Subject (Algebra, Numbers & Operations, Geometry, Measurement, and Data Analysis & Probability) it is hard not to like this great resource.
