Site Title

National Library of Virtual Manipulatives

Objective of the Site

It helps students understand mathematical concepts by using interactive manipulatives.

Intended Audience

It is mainly designed for students and the parents. However, teachers can use this site to teach their students mathematical concepts. University instructors can use this website in their classrooms teaching their pre-service teachers mathematical concepts by using interactive manipulatives.

Domain Related Aspects

This site is an educational site designed for teaching mathematics to elementary, middle and high school students. The site includes many types of manipulatives that teachers can use in motivating their students in learning mathematical concepts.

Structure of the Site:

The website's mathematical concepts are divided to five areas: number sense and operations, algebra, geometry, measurement, and data analysis and probability. Each of this area is divided to four grade-level sections: Pre-K-2, 3-5, 6-8, and 9-12. Students can click on the content area they are interested.

Usefulness and Richness of Each Topic

I recommend this site to mathematics teachers, specially elementary mathematics teachers because this site contains many interactive mathematics activities which enhance student learning. The philosophy of this site is based on understanding of mathematics concepts rather than drilling and memorizing them. Many elementary mathematics teachers do not have manipulatives such as base ten blocks, tangram, geoboard, pattern blocks, attribute blocks, and others resources in their classrooms. They simply can get access to this Web in just a few minutes and click on these manipulatives designed at different grade levels. By using this Web, students are active participant in learning, for example to add 37+18, the web would display 3 longs, which represent 30, and seven small units, which represent the number even, and for 18, it will display one long and 8 units. …
