Fractions Decimals Percentages

This math app is about visually exploring how percentages and decimals are just special kinds of fractions with their own notation. There are no tasks to complete or problems to solve. The purpose is to build conceptual understanding.
By painting different grids and circles with one or more colors students can see how their coloring changes the fraction, decimal, and percentage amounts of those colors. Grids and circles can be very simple and have only 1 square or sector, or very large with up to 10,000 squares or 360 sectors.
Common Sense Media: "Use Visual Fractions Decimals and Percentages in the classroom to support math lessons. Use a number form alone (just fractions, for example), or use multiple forms together for older kids learning about the relationship between these three forms. As an alternative to creating paper and pencil models, kids can use the app as they complete assignments that require representations of numbers using models."
Reviewed by a teacher in a classroom setting - Teachers With Apps: “There are no problems to complete or solve, this app is designed as a handy tool to help student’s build conceptual understanding of these three related concepts. From the expressions on the faces of the students we worked with this Visual Fractions Decimals and Percentages provides just that in a very user friendly format, this app can make all the difference in establishing a better understanding for all future work in this realm of math.”
