The parents' guide to what's in this app.

Educational Value

Kids can learn how to multiply single-digit numbers using a conceptual approach that incorporates the distributive and commutative properties of multiplication. For each problem that they have to solve, kids get an area model and have to drag wooden bridge planks into the model in order to fill it. For example, to solve 3 x 5, kids can drag a 2 x 1 plank into the model to represent 2 x 5. They tap a number line to show that 2 x 5 = 10. Then they drag a 1 x 1 plank to fill in the model, tapping the number line again to show that 3 x 5 = 15. The conceptual approach in Teachley: Mt. Multiplis is an excellent way to help kids understand multiplication and build fact fluency.

Ease of Play

Gameplay is intuitive, and the cleanly designed graphics make navigation easy. 

Violence & Scariness

A plane crash is part of the story line, but no images of the wreck are used. 

Sexy Stuff

What parents need to know

Parents need to know that Teachley: Mt. Multiplis is a math game that teaches kids how to multiply. Kids solve problems using area models and number lines to help a cute character, Linka, build bridges and make her way through the city of Mt. Multiplis. As kids build bridges, they can unlock treasures, collect gems, and eventually rebuild Linka's plane to help her get home. Through the use of interactive models, the game teaches kids a conceptual understanding of multiplication.

What's it about?

A character named Linka has crashed her plane in a storm and needs to build bridges to reach her plane and rebuild it. Kids help Linka by solving multiplication problems, collecting gems, and building bridges. As kids tap on an area to start building, they're given a multiplication problem to solve. Kids have to drag planks into an area model to fill the model and solve the problem. They earn gems for solving the problem correctly, and they can use the gems to build the bridge. As Linka gets closer to her plane, the plane gets built, piece by piece, as kids complete a level. A Parents and Teachers section provides information about the Common Core standards coverage and gives users access to general game settings and development credits.

Is it any good?

The nice thing about TEACHLEY: MT. MULTIPLIS is that kids have the opportunity to visualize and develop an understanding of multiplication, which is a much more meaningful approach than simply using tables to teach through memorization. The story line is fun, and kids will enjoy collecting gems and building bridges while striving to reach the end goal of rebuilding Linka's plane. Kids stay engaged by dragging planks into the area models and then tapping on the interactive number line. A useful addition to the game would be some detailed feedback that pops up after kids make at least one or two attempts to solve a problem but continue to struggle. 

Talk to your kids about ...

  • Families can talk about multiplication in everyday life. For example, if you're at the grocery store, ask kids how many apples there are in all if you have four bags with five apples in each bag. 

  • Practice using pencil and paper. Give kids problems to solve and let them use their own strategies to solve them.
