 # Lesson Plan: Stars - Math Subject:  Math

Lesson Objective: To use multiplication and division to solve word problems

Common Core Standard:  CCSS.MATH.CONTENT.3.OA.A.3- Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.

Materials:

Starter:

Say:

• How do you know when to use multiplication and when to use division? (Allow the students to answer.)

Main:

Say:

• Knowing when to use multiplication and when to use division is very important when you are solving word problems.

• Who remembers some of the key words to look for in word problems that will help you decide whether to use multiplication or division?  (Allow the students to answer)

• Some of the key words that might be used in words problems that use multiplication are by, double, every, product and times.

• Some of the key words that might be used in word problems that use division are as much as, how many in each, quotient and share something equally.

• To solve a word problem, you first need to understand the situation that is being described.  You then need to figure out what you are supposed to be solving.

• If there are diagrams or pictures, use those to help you understand what you need to solve or to help you find the numbers that you need to write an equation.  You can do this by drawing a picture or writing an equation or word sentence with a circle where the missing information would go.

• Now, you are going to be doing some word problems.  All of the word problems will use either multiplication or division.  When you are done, we will go over all of the answers.

• Does anyone have any questions?

Feedback:

Say:

• Who would like to share your answers?  (Allow the students to share.)
