A lot or a little?

The parents' guide to what's in this app.

Educational Value

Kids can learn to use technology, improve their current math skills, and build fluency with ModMath. The app works to ensure all math problems are easy to read. Kids often have trouble properly lining up place-value digits, particularly when regrouping is involved. For students with dyslexia and dysgraphia, practicing math problems can be particularly challenging. By using the virtual graph paper, kids can worry less about writing neatly and focus more on solving equations. Kids won't learn new math skills with ModMath, but this assistive tool is great for creating legible math equations.

Ease of Play

Kids may need to spend some time practicing with the keypad, but navigation is pretty simple.

What parents need to know

Parents need to know that ModMath is a program that displays virtual graph paper, which kids can use to set up math equations. Kids can create worksheets by simply tapping in a cell of the graph paper to make a keypad appear. As kids enter their equations, the program aligns numbers and symbols in neat columns and/or rows so the equations are clearly legible. This makes it easier for kids to solve the equations, especially if they need to regroup or do long division. Kids can adjust color settings, save their worksheets, and create PDFs to share or print. It's important for parents to note that only one problem can be typed per worksheet. However, kids can email multiple worksheets as a single page.

What's it about?

A blank sheet of graph paper appears when kids first open MODMATH. Tap in a cell, and a keypad appears. Kids then use the keypad to enter the numbers and symbols for their equations and hit the "done" button when they're finished. Icons across the top of the screen allow kids to add new worksheets, adjust the color settings, resize symbols, and access a detailed information screen. If they need to find a specific sheet, there's a searchable library. There's also an icon that kids can tap to manage their sessions; a session includes all the worksheets created on a particular date. Kids can email and print entire sessions or selected worksheets.

Is it any good?

It doesn't have a lot of bells and whistles, but its clean and simple design makes it an ideal tool for typing equations and their solutions. According to the developer's website, the app was initially created to help a child with dyslexia and dysgraphia. However, any child who needs to write and solve math equations could benefit from using it. Not only does the app help keep math problems legible, it also helps kids learn to use technology, an essential skill to master these days. 

Talk to your kids about ...

  • Families can talk about how to use the keypad. Spend some time working with kids to help them get the hang of it.

  • Have kids write a math problem on paper first, and then use the app to type the same problem. Discuss the importance of aligning place-value digits when solving equations.
