Area Model Review

Front

What is the area model in mathematics?

Back

The area model is a visual representation used to illustrate multiplication and division. It breaks down numbers into smaller, more manageable parts to help understand how to calculate the area of rectangles.

Front

How do you calculate the area of a rectangle?

Back

Area = Length × Width. For example, if a rectangle has a length of 5 units and a width of 4 units, the area is 5 × 4 = 20 square units.

Front

What does the term 'square units' mean?

Back

Square units are a measure of area. They represent the number of unit squares that can fit into a given area.

Front

If a rectangle has an area of 24 square units and a width of 4 units, what is the length?

Back

Length = Area ÷ Width. So, Length = 24 ÷ 4 = 6 units.

Front

What is the relationship between multiplication and area?

Back

Multiplication can be used to find the area of a rectangle by multiplying its length and width.

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 3 × 4 = 12, both 3 and 4 are factors.

Front

What is the product of 12 and 5?

Back

The product is 60, as 12 × 5 = 60.

Front

How can you use an area model to multiply 12 by 5?

Back

You can break down 12 into 10 and 2, then multiply: (10 × 5) + (2 × 5) = 50 + 10 = 60.

What is the area of a square with a side length of 3 units?

Back

Area = Side × Side = 3 × 3 = 9 square units.

Front

If you know the area of a rectangle is 30 square units and the length is 6 units, what is the width?

Back

Width = Area ÷ Length. So, Width = 30 ÷ 6 = 5 units.
