Quality of Technological Interactivity: Strong (2)
You must have Java to use this virtual manipulative.
This is not a game where interactivity is designed to increase motivation, the interactivity is to demonstrate a variety of models of multiplication.

Quality of Explanation of the Subject Matter: Not Applicable (N/A)
Instructions are given to elaborate on each setting (Grouping - Area Model, Lattice Algorithm, or Common Algorithm), but they are not designed to explain the subject matter.
My GED Preparation students often have trouble distinguishing between area and perimeter even when they can recite a formula for each. We spent just a matter of minutes using this manipulative, but I used it (on the 'grouping' setting) in conjunction with Illuminations' Multiply and Conquer Lesson. It was very effective; now they can visualize area.
