FEATURED APP

Welcome to
Mt. Multiplis

Mt. Multiplis, free for iPad, teaches complex multiplication strategies to students in 3rd-5th grades.

Produced by teachers and researchers, award-winning game designers, and noted voice talent, Mt. Multiplis encourages children to solve problems in different ways using the properties of multiplication.

Not All Education Apps
Are Created Equal

We don’t rely on digital flashcards and worksheets.

Mt. Multiplis allows children to use properties of multiplication to think flexibly about solving problems.

Visual Models To Aid Learning

Children who struggle fail to learn key math strategies. That’s why our apps make these explicit, helping students conceptualize complex strategies using models, like the ones shown here:

1.

2.

3.

1. To solve 7 x 8, kids can drag over 5 planks of 8 to make 40.
2. Then, they can drag over two more planks of 8 to make 56.
3. After solving the problem, they reflect on their work using formal notation.

Common Core Aligned

Mt. Multiplis addresses several Operations and Algebraic Thinking standards, including 3.OA.B.5. Apply properties of operations as strategies to multiply:

Commutative property of multiplication
If 6 × 4 = 24 is known, then 4 × 6 = 24 is also known.

Associative property of multiplication
3 × 5 × 2 can be found by 3 × 5 = 15, then 15 × 2 = 30, or by 5 × 2 = 10, then 3 × 10 = 30.

Distributive property
Knowing that 8 × 5 = 40 and 8 × 2 = 16, one can find 8 × 7 as 8 × (5 + 2) = (8 × 5) + (8 × 2) = 40 + 16 = 56.

For Us Games Are a Serious Subject

As former teachers and experts in cognition and learning we're dedicated to using research to better understand how kids learn. Research shows strategies drive learning. By promoting conceptual understanding and fact fluency children don't just solve problems, they come away with new tools for learning math.

Supported by Research

Our apps are driven by cognitive science research. That means Mt. Multiplis is designed to best support children’s learning.
