Description
Students can use this virtual manipulate to explore and practice division using pictures.
-
The grid shows a big number divided by a little number. The big number is the total number of blue and red blocks. The little number is the height of the blue rectangle. The number of red blocks is the remainder left over when the big number is divided by the little number.
-
To the right of the grid, the big number is shown to be the little number times another number plus the remainder.
-
The number of pieces that the grid is divided into can be changed by using the radio buttons below it.
-
With the Show Me option selected, the results of dividing a number by another by dragging the slider to the left of the grid can be explored.
-
Selecting the Test Me option will result in being given a division problem to solve. The user can move the slider to create a picture representing the division problem. Then the user should fill in the text boxes to the right with the answer. By clicking Check, the manipulative will tell you if the answer is correct.

The National Library of Virtual Manipulatives is a three-year NSF supported project to develop a library of uniquely interactive, web-based virtual manipulatives or concept tutorials, mostly in the form of Java applets, for mathematics instruction (K-8 emphasis). The project includes dissemination and extensive internal and external evaluation. For more information, please visit http://nlvm.usu.edu/en/nav/vlibrary.html.
