What is the area model in multiplication?

Back

The area model is a visual representation of multiplication that breaks down numbers into their place values to simplify the calculation.

Front

How do you calculate the perimeter of a rectangle?

Back

Perimeter = 2 × (Length + Width). For example, if Length = 363 and Width = 92, then Perimeter = 2 × (363 + 92) = 910.

Front

What does it mean to compare costs?

Back

Comparing costs involves determining how many times more one cost is than another. For example, if renting a theater costs $42 and popcorn costs $6, then it costs 7 times more to rent the theater.

What is the product of 81 and 27?

Back

81 X 27 = 2,187.

Front

How do you divide a number with a remainder?

Back

When dividing, if the number does not divide evenly, the remainder is the amount left over. For example, 3,787 ÷ 5 = 757 R2.

Front

What is multiplication?

Back

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

Front

What is division?

Back

Division is the process of splitting a number into equal parts. For example, 12 ÷ 4 means splitting 12 into 4 equal parts, which equals 3.

Front

What is a rectangle?

Back

A rectangle is a four-sided shape (quadrilateral) with opposite sides that are equal in length and four right angles.

Front

What is the formula for the area of a rectangle?

Back

Area = Length × Width. For example, if Length = 5 and Width = 3, then Area = 5 × 3 = 15.

Front

What is a remainder in division?

Back

A remainder is the amount left over after division when the number cannot be divided evenly. For example, in 10 ÷ 3, the quotient is 3 and the remainder is 1.
