How do you find the product of 23 x 15 using the area model?

In this lesson you will learn how to multiply multi-digit numbers by using the area model.

Let’s Review Product – The result when two numbers are multiplied. For Example: 4 x 5 = 20 product

Multiplication is repeated addition x 5 Multiplication is faster!

Multiplication sentences can be represented by using an array x 6 = 24

Multiplying by powers of x 10 = x 100 = 3, x 1,000 = 36,000

A Common Mistake Multiplying each digit as if it represents a number of “ones.” It is important to remember the place value of each digit. 36 x 5 = 30 x x 5

Let’s Review Core Lesson Multiply 23 x 15 using the area model x

Let’s Review Core Lesson Multiply 225 x 12 using the area model x

In this lesson you have learned how to multiply multi-digit numbers by using the area model.

Let’s Review Guided Practice Multiply 352 x 32 using the area model.

Let’s Review Extension Activities In your math journal, draw an area model to find the product of 542 x 78.

Let’s Review Extension Activities x Roll a dice 4 times to fill in the blanks and create a multiplication problem like the one below. Use the area model to find the product.

Let’s Review Quick Quiz 1). Find the multiplication sentence that matches the model below  24 x 37  47 x 23   60 x 10

Let’s Review Quick Quiz 2) Multiply 351 x 62 using an area model.
