4 Dice is an iPad app designed to help students learn to add, subtract, multiply, and divide fractions. The app was developed by the same people that built the popular 5 Dice app that helps students learn the order of operations.
In 4 Dice students are shown a fraction and they have to drag four dice into position to complete the arithmetic that will result in the fraction that they were shown. It’s kind of like the Jeopardy concept applied to fractions mathematics. There are five modes in 4 Dice. There are the addition, subtraction, multiplication, and division modes as well as a challenge mode that randomized the problems. At any point in a series of problems students can pause and use the whiteboard to work out possible solutions to a problem.
4 Dice does ask for an email address, but doesn’t ask users to confirm that email address. If your students don’t have email addresses you can use the Gmail+1 trick to create dummy addresses for them that you can monitor.
4 Dice costs $0.99. This app is appropriate for elementary and middle school students.
