Multiplication - Grade 4 (Mod. 4)

Front

What is multiplication?

Back

Multiplication is a mathematical operation that represents the repeated addition of a number. For example, 3 multiplied by 4 (3 x 4) means adding 3 four times (3 + 3 + 3 + 3 = 12).

Front

What is the product of two numbers?

Back

The product is the result of multiplying two or more numbers together. For example, the product of 5 and 6 is 30 (5 x 6 = 30).

How do you find the total number of items when each group has the same number of items?

Back

You multiply the number of groups by the number of items in each group. For example, if there are 4 groups of 6 apples, the total is 4 x 6 = 24 apples.

Front

What is an array in multiplication?

Back

An array is a visual representation of multiplication using rows and columns. For example, a 3 by 4 array shows 3 rows of 4 items each, representing 3 x 4 = 12.

Front

What is the commutative property of multiplication?

Back

The commutative property states that changing the order of the numbers in multiplication does not change the product. For example, 2 x 3 = 3 x 2.

Front

What is the associative property of multiplication?

Back

The associative property states that when multiplying three or more numbers, the way in which the numbers are grouped does not change the product. For example, (2 x 3) x 4 = 2 x (3 x 4).

Front

What is a factor in multiplication?

Back

A factor is a number that is multiplied by another number to get a product. For example, in 6 x 4 = 24, both 6 and 4 are factors.

How do you solve a multiplication word problem?

Back

Read the problem carefully, identify the numbers involved, determine if you need to multiply, and then perform the multiplication to find the answer.

Front

What is the area of a rectangle?

Back

The area of a rectangle is found by multiplying its length by its width. For example, if a rectangle has a length of 5 meters and a width of 3 meters, its area is 5 x 3 = 15 square meters.

Front

What is a multiplication table?

Back

A multiplication table is a chart that shows the products of pairs of numbers, typically from 1 to 12. It helps in learning and memorizing multiplication facts.
