Teachley Mt. Multiplis

About this app

Winner of Editor's Choice Award - Children's Technology Review and Parent's Choice Award! What are people saying? “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., 3rd 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 Common Core Math Standards: -3.OA.A.1 -3.OA.A.3 -3.OA.A.7 -3.OA.B.5 About Teachley: Founded by former teachers, Teachley uses cognitive science research to create apps that teach effective learning strategies and assess what kids know within engaging games.
