Math Applet- Percent Grids

Summary: This applet is all about teaching percentages using a grid. This applet has three settings in which you can use to figure out percentages. The first setting is an explore setting. Through this setting you fill in box's on the grid, and then write what percentage that shows. This applet will tell you if you are correct or not. The next setting is the "show" setting. In this a percent will be listed such as 50%. You will have to fill in 50% of the box's on the grid. At the top of the applet shows what percent you are filling in so you know if you are correct. The third setting is called "name". This is where the applet presents you with a picture of a grid with a certain amount of box's shaded in. You have to type in the correct percent that is shown, and the applet will tell you if it is correct or not. The applet uses a neon green color to make it visually appealing.

Critique: I really enjoyed this applet. I feel that it is very hands on which can be very beneficial to students. There is also a variety of methods used to show percentages. The thing I really enjoy is that with this applet it gives the opportunity for students to be able to explore percentages and see what a certain percent really means and what it looks like. This applet also allows students to test their knowledge of percentages as well. This applet would be a great tool to introduce percentages (in the explore setting) and also to test knowledge or review knowledge of percentages (in the show and name settings). The standards that are listed for this applet directly correlate to the applet as well. This tool can be very beneficial for students, especially if they are visual or hands on learners.
