This game is a great way to introduce multiplication in the classroom. Have kids work in pairs to complete a level, and then reinforce what they learn through class discussion. Multiple-user accounts aren't an option, so create a class leaderboard to track progress. Kids can write their own multiplication problems and have their partners draw area models to model and solve the problems.Continue reading Show less
A character named Linka crashed her plane in a storm and needs to build bridges to reach the plane and rebuild it. Kids help Linka by solving multiplication problems, collecting gems, and building bridges. As kids tap each area, they're given a multiplication problem and must drag planks into an area model to fill the model and solve the problem. Kids earn gems for solving problems correctly, and they can use the gems to build bridges. As Linka gets closer to her plane, the plane is rebuilt, piece by piece, as kids complete levels. A Parents and Teachers section provides information about the Common Core standards coverage, and gives users access to general game settings and development credits.
Teachley: Mt. Multiplis is a math game that teaches kids how to multiply single-digit numbers using a conceptual approach that incorporates the distributive and commutative properties of multiplication. For each problem they have to solve, kids view an area model and they have to drag wooden bridge planks into the model to fill it. For example, to solve 3 x 5, kids might 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. This conceptual approach is an excellent way to help kids understand multiplication and build fact fluency. 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 brides, 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 the interactive number line. A useful addition to the game would be detailed feedback that pops up after kids make one or two unsuccessful attempts to solve a problem.

Operations And Algebraic Thinking
Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of Grade 3, know from memory all products of two one-digit numbers.
Interpret products of whole numbers, e.g., interpret 5 × 7 as the total number of objects in 5 groups of 7 objects each. For example, describe a context in which a total number of objects can be expressed as 5 × 7.
Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.1
Apply properties of operations as strategies to multiply and divide.2 Examples: If 6 × 4 = 24 is known, then 4 × 6 = 24 is also known. (Commutative 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. (Associative property of multiplication.) 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. (Distributive property.)
