ModMath ModMath teaches users how to line up math problems. When launched, ModMath provides users with a piece of graph paper. Users must tap the cell in which they want to input a number or symbol, and ModMath highlights the cell and pulls up a calculator. Users then type the number or symbol into the cell using the calculator. As they enter information, ModMath automatically moves the highlighted area to the next on the right.

A Must-Have App for Elementary Math Students

8ModMath teaches users how to line up math problems. When launched, ModMath provides users with a piece of graph paper. Users must tap the cell in which they want to input a number or symbol, and ModMath highlights the cell and pulls up a calculator. Users then type the number or symbol into the cell using the calculator. As they enter information, ModMath automatically moves the highlighted area to the next on the right. (**Please note:** The calculator will not solve the problem, it is used to only add numbers and symbols to the graph paper.) Users must manually input the numbers and symbols onto the graph paper using the calculator to solve the problem. Users can add new pieces of graph paper by tapping the “+” button on the top left of the screen, and ModMath will automatically save the paper they were using before adding the next piece of paper. Users can access saved pieces of paper by tapping the “folder” button, which is also located on the top left of the screen.

### Instructional Ideas

- Teachers can have students use this app to help them correctly line up a math problem.
- Teachers can have students solve math problems using this app. To do so, students will have to line up the math problem correctly and then solve it using this app. Once solved, teachers can have students take a screen shot of their work and email it to them or post it to a class website for grading.
- Teachers can use this this app to build a math resource for students. To do so, teachers can demonstrate how to correctly line up and solve a math problem. While they demonstrate, students can be responsible for copying the math problem and its solution into this app on their iPad. That way, students will have a reference point that they can access as they work to solve practice problems independently after the lesson.
