The NLVM combines the organization of sites such as NEIRTEC and the Select website (see below) with true, high quality manipulatives. National Library of Virtual Manipulatives
Version 3: The range of the numerator and denominator is limited to values from 0 to 100. Version 2: The range of the numerator and denominator is limited to values from 0 to 20. Version 1: The range of the numerator is limited to values from 0 to 20 and the denominator is limited to benchmark values 1, 2, 4, 5, 8, 10, and 20. The purpose of Illuminations is to "provide Standards-based resources that improve the teaching and learning of mathematics for all students" and "provide materials that illuminate the vision for school mathematics set forth in Principles and Standards for School Mathematics".įraction Model-grades 3-8: explore several models for representing fractions with adjustable numerators and denominators. The NCTM site also contains the Illuminations page, including 102 manipulatives, lessons based on NCTM standards, and links to related online activities. 9-12: Explore vectors use graphs, equations, and tables to investigate elimination of medicine from the body explore inscribed figures, linear regression, and linear functions.6-8: Visualize the concept of multiplication, investigate rate of change, length, perimeter, area, volume, congruence, similarity, and symmetry, and the Pythagorean Theorem.

3-5: Communicate about math using games, use simulation software to investigate distance, rate, and time investigate data.preK-2: Investigate patterns, triangles and properties of polygons, geometry and measurement develop spatial skills by using tanagrams, learn estimation strategies.How clear are the instructions for use? (CITE).Will teachers need to provide feedback and support?.Can the level of difficulty be adjusted for different students?.The Center for Implementing Technology in Education lists several factors to consider when selecting virtual manipulatives: However, researchers and authors caution "Although virtual manipulatives provide some support for individual student use, as with physical manipulatives, students benefit from teacher guidance to help them use the manipulative correctly and connect to the underlying math" (CITE). Virtual manipulatives are often accompanied by usage instructions and hints to help students use them successfully, making independent use possible.

The virtual manipulative sites described below are accompanied by lesson plans for teachers describing how to use them effectively in teaching mathematics. How to use Virtual Manipulatives Effectively Some research shows Virtual manipulatives may lead to more complex, richer understandings of concepts than through use of concrete manipulatives (CITE). Research has shown that concrete manipulatives help students better understand abstract concepts in math, and comparative studies show virtual manipulatives to be as effective as concrete ones.
