## What is Fraction as Slope?

Fraction as Slope helps students explore fractions and slope visually.

The app shows how fractions can be understood as slopes of lines. Students can draw and move graphs of lines to explore, compare, add, subtract, reduce, and expand positive and negative fractions. This gives algebra students a visual way to build conceptual understanding of both fractions and slopes.

Students can see equivalent fractions as lines with the same slope, compare fractions by comparing their slopes, and explore how changing a numerator or denominator changes the graph.

Teachers With Apps:
“Fraction as Slope by Esa Helttula of iDevBooks is simply elegant. It is written for big kids with a design that respects and lends gravity to what they are learning. The app is simply composed of an adjustable grid where numbers are plotted along an axis so that you can visually see a slope of that fraction with all its equivalents.”

GeekDad:
“Fraction as Slope allows your kids to play around with graphed lines and see the connection between fractions and slopes. It’s a straightforward, targeted learning app, and kids will enjoy manipulating the graphs manually.”

Features:

- Explore fractions as slopes of lines
