Another free app from MathTappers. This app is designed to help learners build mastery and fluency in converting between fractions, decimals and percent. The visual model presented has 3 modes - just slide your finger sideways across the model at the top of the screen to find the model that is most useful to you. As always we would like to encourage learners to build mastery first - then worry about speed. Parents, tutors and teachers, might challenge learners to share their strategies and explain their choices.
