Teachley: Mt. Multiplis

By Teachley

Open iTunes to buy and download apps.


“Mt. Multiplis is not just focused on getting the answer, but also understanding the process of multiplication and the strategies that kids need to develop. I love how this app supports my students’ thinking in a way no other app does.” - Alana S., K-5 Special Education Teacher

“I really like how Mt. Multiplis combines the area model and the number line. It’s helped my students demonstrate their understanding across representations.” - Yvette B., third grade teacher

About the game:
Linka gets caught in a terrible storm while flying home after a successful treasure hunt. She escapes but her plane isn’t as lucky. Help Linka make her way through Mt. Multiplis by building bridges, unlocking treasure, and earning gems. Rebuild Linka’s plane by collecting the pieces from the greedy Crags who live on the island.

Developed by teachers and experts in children’s cognition and learning, Mt. Multiplis is an engaging game that teaches multiplication through the commutative and distributive properties. While most multiplication apps focus on drill with digital worksheets and flashcards, Mt. Multiplis scaffolds learning to promote conceptual understanding, efficiency with multiplication strategies, and fact fluency.

The Common Core State Standards expect third graders to use the distributive property when multiplying (CCSM.3.OA.B.5): “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.” Mt. Multiplis is designed to make this complex content more approachable and fun for kids. Students can think strategically, seeing how 7 x 8 is the same as 5 groups of 8 plus 2 more groups of 8.

Supports Response to Intervention programs:
Mt. Multiplis is a great tool for classroom teachers looking to differentiate instruction for students. The app is also great for parents who want to support their children’s learning.

Recommended Grades: 3rd-5th (6th-8th intervention)

Meets Several Common Core Math Standards:
-3.OA.A.1 -3.OA.A.3 -3.OA.A.7 -3.OA.B.5

Gets at the heart of multiplication

Finally, an app that focuses on what makes multiplication hard! I've seen too many kids struggle to memorize their multiplication facts, but not have the number sense to figure out the answer when they forget. I am so excited that this app helps kids develop that number sense and shows them how to use it to multiply. The feedback is great, "6 x 8 is just 5 groups of 8 plus one more 8."


Finally a multiplication app that isn't just flash cards! You can see a real visual representation of the problem you're trying to solve. Collecting gems encourages my kids to solve the problem in the fewest amount of moves! A great motivator to help get gems and pay off these funny characters blocking your path!


Another great app from Teachley!! My kids love addimals and now my oldest is addicted to mt multiplis...I am so happy he loves this game instead of just playing wii. His multiplication abilities have already shown great improvement in just a few days since I downloaded the app. Great app and keep making more!
