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

Educational Value

Kids can learn about concepts related to multiplication and division. They learn about the commutative property of multiplication and that multiplication is repeated addition. They can also learn about the relationship between multiplication and division by exploring the Toolbox Hundred Board. A setting allows kids to set parameters for one of the factors in multiplication, or the divisor in division, so they're within a range of 1 to 10. They may drag dots on a hundred board to show the commutative property of multiplication, tap the screen to show multiplication as repeated addition, or drag objects to partition them into equal groups. Kids also use mental math strategies by simply writing the solution to a problem using their fingers. Understanding Math - Times Tables: Learn to fluently multiply and divide within 100 offers an interesting approach to math practice, but its glitches and limited support hinder its learning potential.

Ease of Play

Information is nicely organized, and navigation is intuitive. Touchscreen controls have some glitches.

What parents need to know

Parents need to know that Understanding Math – Times Tables: Learn to fluently multiply and divide within 100 is an elementary math practice tool that emphasizes the use of objects and senses to build comprehension. Kids can select from several modes of play, which present multiplication and division problems using objects and equations. Kids have to constantly drag, tap, and/or draw with their fingers. Though this approach is good in theory, it can become a bit redundant in practice. The app is available for purchase in 16 languages, including English, French, Spanish, and more.

What's it about?

In UNDERSTANDING MATH – TIMES TABLES: LEARN TO FLUENTLY MULTIPLY AND DIVIDE WITHIN 100, there are six options for play. In the Hundred Board, kids find the product by dragging an interactive hundred table to represent two factors in a multiplication problem. In Multiplication, kids tap their fingers on the screen to represent a multiplication problem as repeated addition. For example, for 5 x 3, they tap five fingers three times or three fingers five times; the factors appear as objects, and the product appears in the equation. Kids can pop the objects before moving on to the next problem. In Division, kids drag objects into boxes to form equal groups. If done correctly, the quotient automatically appears. Kids can also write the quotient on the screen. In Training, kids write solutions to problems, and a model is provided at the bottom of the screen. In Duel, kids can compete with another player, and each player can select a difficulty level between 1 and 4. The first to enter the correct solution wins a star, and five stars wins the game. Finally, in Toolbox, kids manipulate an interactive hundred board to explore multiplication and division. The game accommodates multiple users and tracks each user's performance.

Is it any good?

This game provides an engaging and innovative way for kids to work with fundamental math concepts and is best suited for practice rather than instruction. The models used to represent and solve problems should help kids build and retain comprehension, but without feedback and access to instructional hints the learning experience is limited to practice or remediation. The opportunities to earn rewards and challenge another player motivate kids to improve fluency. However, there are some minor issues with the touchscreen controls. For example, tapping the screen for larger factors, such as 9 or 10, can be very difficult. If all fingers do not tap at the same time, kids get the answer wrong. Writing answers with a finger is also a challenge; the program often does not recognize a handwritten number, even if it is written properly.

Talk to your kids about ...

  • Families can talk about the relationship between multiplication and division, using the Toolbox mode as a model. Give kids multiplication equations, such as 4 x 3 = 12, and have them write two related division problems.

  • Compete with kids in the Duel mode. Be sure to select 4 as your level, and challenge kids to choose the highest level possible for themselves.
