Users must tap the option and Math 42 performs it on the expression. On the top of the app are additional buttons. The “Lined” button lets users view the expressions they entered into the app. The “Graduation Cap” button lets users train, take tests, and view their scores. When training, users are presented with a multiple-choice question, and they must manipulate the equation correctly to solve it. For each training problem, users can tap the “Show Solution” button to see how the correct answer was determined. The “Graph” button will plot the expression on a grid. The “Gear” button lets users personalize their experience using the app. The “Upload” button lets users share their work via email, and the “+” button clears the current work and lets users start over with a clean workspace.

Instructional Ideas

  1. Teachers can allow students to use this app when solving problems.
  2. After entering an expression into this app, students can tap an option below the expression such as “Simplify Expression” or “Factor Expression.” Next, students can be required to write out how the app manipulated the expression. This activity will build students’ mathematical literacy and help students communicate mathematical procedures.
  3. Teachers can require students to first solve an expression and then graph it by hand. Students can then use this app to check their work.
  4. Teachers can have students use the training and test options in this app to review for an upcoming test. Or, teachers can start a friendly class competition to see who can get the highest score the quickest with the test option.
