Visual Fraction and Multiplication Table Bundle

By Esa Helttula

This app is only available on the App Store for iOS devices.


This bundle has three iDevBooks visual math apps that build conceptual understanding. Save 50% compared to buying the apps separately.

Visual Fractions Decimals and 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.

The app has been featured by Apple in "Education - Middle School" and ‘Education - Best New Apps’

Fraction as Slope

The Fraction as Slope app provides algebra students a new visual way to think about slope and fractions by showing how fractions are slopes. This provides an opportunity to increase conceptual understanding of both fractions and slopes.

Students can explore, compare, add, subtract, reduce, and expand positive and negative fractions just by drawing and moving graphs of lines.


-Explore equivalence classes of fractions
-Visually compare fractions using slopes
-Visually reduce and expand fractions
-Learn a new visual way to add and subtract fractions with uncommon denominators

Visual Multiplication Table

Multiplication Table is a groundbreaking new way to visualize and interact with the multiplication table. It is created by a lover of math who appreciates the patterns and order to be found within the discipline. The multiple exploratory ways to interact with the multiplication table will help you teach your child to think about multiplication as a visual, orderly, and most importantly – understandable concept. "I highly recommend it for any kid who is learning their multiplication tables".
