Grade 3,Operations and Algebraic ThinkingCluster: Multiply and divide within 100

Standard: 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 one-digit numbers.

Grade 3,Operations and Algebraic ThinkingCluster: Understand properties of multiplication and the relationship between multiplication and division

Standard: Apply properties of operations as strategies to multiply and divide. 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.) (Students need not use formal terms for these properties.)

Cluster: Mathematical practices

Standard: Look for and make use of structure. Mathematically proficient students look closely to discern a pattern or structure. Young students, for example, might notice that three and seven more is the same amount as seven and three more, or they may sort a collection of shapes according to how many sides the shapes have. Later, students will see 7 × 8 equals the well remembered 7 × 5 + 7 × 3, in preparation for learning about the distributive property. In the expression x^2 + 9x + 14, older students can see the 14 as 2 × 7 and the 9 as 2 + 7. They recognize the significance of an existing line in a geometric figure and can use the strategy of drawing an auxiliary line for solving problems. They also can step back for an overview and shift perspective. They can see complicated things, such as some algebraic expressions, as single objects or as being composed of several objects. For example, they can see 5 – 3(x – y)^2 as 5 minus a positive number times a square and use that to realize that its value cannot be more than 5 for any real numbers x and y.

Grade 3,Operations and Algebraic ThinkingCluster: Solve problems involving the four operations, and identify and explain patterns in arithmetic

Standard: Identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations. For example, observe that 4 times a number is always even, and explain why 4 times a number can be decomposed into two equal addends.

Grade 4,Operations and Algebraic ThinkingCluster: Gain familiarity with factors and multiples

Standard: Find all factor pairs for a whole number in the range 1-100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1-100 is a multiple of a given one-digit number. Determine whether a given whole number in the range 1-100 is prime or composite.

I like that our students can use this interactive practice to build their multiplication, division, and factoring fluency. It is easy to use. And even better it works within our myopenmath.com courses. We can track the time they spend practicing their arithmetic.

## Quality of Technological Interactivity: Superior (3)

Students can choose from 3 different mathematic operations/skills, 3 different levels, and whether to be timed or not. Students stay engaged to beat the clock and hear the sound effects of the game.

How nice to have an interactive multiplication table like this where one could drill multiplication/division fact families. I like level 2 where the table only goes up through 9. That's all you really need to know. This tool will be helpful to many where I teach.

## Quality of Assessments: Not Applicable (N/A)

The arithmetic workout can be timed and therefore used as an assessment tool itself.

## Quality of Technological Interactivity: Strong (2)

uses Flash

90% of students needed no instruction at all to use this activity.

## Quality of Instructional and Practice Exercises: Not Applicable (N/A)

This resource does not provide an introduction to concepts and skills, but is, in itself, an excellent way to practice skills. There are three different practice options from which users (students) can choose.

## Opportunities for Deeper Learning: Limited (1)

My GED Preparation students loved this! Most used level 3 division and factoring, but everyone could participate by adjusting the level or using the multiplication section, which they find easier. Students were motivated to make the "cash register sound" as fast as possible and I had to ask them to turn their speakers down!

I linked the activity to our class' website so students can practice at home.
