National Library of Virtual Manipulatives

One of my best teacher-friends is a secondary math teacher (and runs the Numbers Rule My World blog), and she is always looking for ways to incorporate technology into her math lessons. She tipped me off about this site that has virtual manipulatives, and I wanted to share it with you guys!

Although my friend uses this site with her secondary students, the National Library of Virtual Manipulatives has something for students PK-12!  It's so rare to find an educational resource that can cater to all ages...I guess that's part of why I think this website is so nice.

The National Library of Virtual Manipulatives is amazing! I love that it is free and easy to use; you don't even have to register before you start using!

The homepage is relatively simple:

Notice how you can view the site in a variety of languages (at the bottom)!

But looks can be deceiving. :)


As you can see, you can access math manipulatives based on the grade of your student(s) or the target skill. Since I'm a teensy bit obsessed with organizing, I particularly love this feature.

Although the homepage isn't anything particularly mind-blowing, once you start clicking on portions of the index, you'll see that the rest of the site is!

So what kinds of things does it have to offer? Unfortunately, I'm going to have to do more telling, rather than showing, because the manipulatives are used through pop-up screens that then start using Java... I'm not even able to take a screen shot of the manipulatives in action...sorry! I've never had an issue taking a screenshot before, so I can't explain this one! Anyway, I clicked on PK-2, and I was presented with the following list of sub-topics:

• Numbers and Operations
• Algebra
• Geometry
• Measurement
• Data Analysis and Probability

And each of those sub-titles had an average of 13 manipulative options underneath it, but you should be aware that that is an average... the "data analysis and probability" sub-topic only had 3 options. Although the graphics aren't anything particularly flashy or high-tech, I feel that they definitely could be used in the classroom. I saw some time-telling activities, graphing options, pattern blocks, etc. I know that most elementary classrooms don't have a 1:1 ratio of students:computers, but you could ask a few students at a time to practice certain math skills during centers!

As for the secondary side of it, I clicked on 9-12, and I was presented with the exact same sub-topic categories as the PK-2 side, but of course, the options underneath each category were drastically different. The sub-topics in 9-12 had an average of about 18 manipulative options underneath it. I saw some great ones in this category, as well. In particular, if I were teaching secondary math (big hypothetical here, folks), I could see myself using the rational numbers triangles, the Venn diagrams, and the geoboards.

If you're a math teacher, give the National Library of Virtual Manipulatives a chance in your class and let me know how it goes!
