A fun, unique, and innovative approach to math instruction for children ages 5 to 12!

Thanks to its Sandbox allowing users to create and interact with mathematical expressions freely, the application helps kids to learn and understand:

• What are addition and subtraction, visually showing them "how it works"
• What do we mean by an equality and an inequality
• What are math symbols ( +, -, =, >,<)
• How to manipulate terms of math expressions and equations (like isolating a variable or moving a number)

With hundreds of built-in exercises, children can practice mental arithmetic and learn the rules of algebra. You can even create new exercises yourself!

Mathematics education organizations strongly advocate the use of manipulatives. They believe manipulatives allow students to actively construct their own understanding of math. Math Wizard is a new generation of virtual manipulatives which allows kids to explore math concepts.

We took special care to make the app fun and engaging so that children love manipulating the different terms of mathematical expressions!

Many settings are available to adapt the application to the child's level, including:

• Numbers can be displayed using digits or beads that visually show the amount that numbers represent
• Voice can be enabled to read numbers and operations aloud
• Numbers available in the sandbox can be customized (the app handles positive and negative integers - up to 10 billion!)
• Choose to allow inequality or force equality
• Animation Speed

You can add as many users as you want, and view the activity history of each user



The sandbox is an open-ended activity that allows users to experiment freely with algebra rules. You can add the numbers you want, and thus create and interact with any expressions or equations you want.

For parents and educators, it's a tool to show what are addition, subtraction, equality and inequality. It also shows users how they can manipulate terms. For students, it's a tool to experiment with numbers in order to better understand "how it works."


The app contains hundreds of built-in exercises (additions, subtraction, equality, inequality, isolate a variable, brain teaser), but you can also create your own exercises!

The goal of each exercise is to reproduce an expression or equation (e.g., "3", "4=4", or "x=3") starting from another expression or equation (e.g., "1+2", "2+2=3+1", "-1+x=2"). This requires the child to interact with the numbers and operators in order to build their understanding of how algebra works (again, the child can only do what is permitted by algebra)



• Positive and negative integer numbers (up to 10 billion!)
• "x" variable
• Expressions with + and - operators
• Equality and inequality
• Division by 2
• Undo/redo operations and manipulations
• Unlimited number of users
• Record user activities

Many settings are available to customize the app, so it can fit the needs of both educators and students:

• Number display mode (beads or digits)
• Voice for numbers and operations
• Custom numbers (Sandbox)
• Do operations by dragging numbers on top of each other
• Authorize inequality
• Authorize division by 2
• Animation Speed

Makes Math Fun!

This interactive math app allows the user to manipulate numbers to support understanding of math principles. Offers excellent visuals, simple instructions, self-paced and exploratory play, and monitors progress. This company continues their excellent tradition of offering intelligent, creative learning applications! Teacher recommended!

Best thing ever!

I love this app because it’s so addicting to learn math (in my opinion) so cool except can you add something to the sandbox? Can you add numbers 6 through 10? Pls? And also BEST THING EVER (edit) can you pls add multiplication and division pls?

Developer Response ,

Thanks your positive review! You can add anything you want in the sandbox : open the settings (gear icon) and look for the « numbers displayed at the bottom » section. - Send and email to if you need more details

Almost great

The graphical explanations are fantastic, and the sandbox is a great idea. Sadly, there is a serious flaw in the exercises portion... The “addition” exercises are really subtraction! There is a 6 up top and 4 down below and the child is to find the number to add below to reach the top. That’s 6-4, which is subtraction. Please include addition exercises! For example, put 2 + 3 up top and have the child select 5 below. That’s addition.

Developer Response ,

The goal of the app is to help kids understand how to manipulate terms in a mathematical expression, and not doing simple quiz such as "2+3". In your example, the goal is to help the child to understand that he must add 2 to 4 to make 6 (so it is an addition). The child has to drag 2 to the bottom part and do the addition. It is a very different process than just doing a simple quiz. However, I think I will add a simple quiz activity because a lot of people are looking for this kind of exercise too. Thanks for your feedback (and sorry for the late answer)
