Use the game as an instructional support and practice tool for kids who are just learning about (or are struggling with) multiplication and division. If possible, kids should work individually to complete a level within one of the two game modes. Then, come together as a class and discuss the models that kids used and how they helped show the meaning of multiplication or division. As an extension activity, have kids create their own models and equations and switch with a partner to solve them.Continue reading Show less
The app is organized into two game modes: Mystery Multiplication and Veggie Divide. Each mode includes 30 levels that begin by helping kids build comprehension and end by reinforcing concepts and helping build fact fluency. In Mystery Multiplication, kids drag veggies into baskets to make equal groups and complete repeated addition sentences. As they progress, kids complete problems that include the multiplication symbol and find missing factors in equations. In Veggie Divide, kids drag veggies to pack them into crates, dividing the veggies into equal groups. Kids eventually complete problems that include the division symbol and find missing numbers to build an understanding of division as the inverse of multiplication. Kids can earn up to three lightning bolt rewards for each correct answer.
Lumio Farm Factor: Multiply and Divide Basics (Full Version) is a game that uses models to teach kids the concepts behind multiplication and division. It supports a handful of Grade 3 Common Core State Standards for math related to Operations and Algebraic Thinking. Kids begin by using concrete models to build an understanding of multiplication as repeated addition and division as repeated subtraction. As they progress through the game, kids learn to use symbols and find missing numbers in multiplication and division sentences. They also build an understanding of division as the inverse of multiplication. If kids struggle to complete a problem, they can access visual cues and hints. Constructive feedback is given for incorrect solutions.
The activities teach good concepts, and the learning potential is strong; the only challenge is that the activities aren't especially compelling. Overall, this is a solid choice for math practice, but kids may need some encouragement to persist through the (sometimes tedious) in-game tasks.
Key Standards Supported
Operations And Algebraic Thinking
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.
Interpret whole-number quotients of whole numbers, e.g., interpret 56 ÷ 8 as the number of objects in each share when 56 objects are partitioned equally into 8 shares, or as a number of shares when 56 objects are partitioned into equal shares of 8 objects each. For example, describe a context in which a number of shares or a number of groups can be expressed as 56 ÷ 8.
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
Determine the unknown whole number in a multiplication or division equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 × ? = 48, 5 = _ ÷ 3, 6 × 6 = ?.
