What's it about?

In NUMBER LINE, BY THE MATH LEARNING CENTER, kids learn to use a number line, which is a visual strategy that helps teach concepts of counting and placing numbers in sequences. Using a number line app can be helpful when completing equations involving addition, subtraction, multiplication, fractions, decimals, and negative numbers. The app allows kids to type in numbers or use a drawing tool to write expressions and equations on the screen. To create math problems to solve, parents can hide certain numbers on the line. Adding a "jump" to the number line creates a diagram, which is helpful for kids to see how numbers relate to each other. For kids who need to see less or more at a time, the spacing between tick marks and numbers on the number line can be customized. There are lots of options to modify and design problems, which could be overwhelming for kids. To share a problem, kids can take a screenshot of the problem or solution and send it via email or messaging.

Is it any good?

Many kids benefit from visual strategies to learn complicated math concepts, and this is a great tool for that, though it may be overwhelming for some. Number Line, by the Math Learning Center allows kids to solve and complete many different kinds of math equations, ranging from simple to challenging. Examples of how to solve equations using a number line aren't included, so parents will need to have a basic understanding of how to use a number line to solve problems in order to get the most benefit from this strategy. Kids who are overwhelmed by a lot of choices may be distracted with the customizable options. Drawing number lines using pencil and paper can take a lot of time and energy to create and lead to careless mistakes. By eliminating this step and using a number line app, kids can focus their attention on solving the problem. For children who have dyscalculia, which impacts the ability to learn new math concepts, the app can be used to help children see how numbers relate to each other.
