Solving Multiplication Word Problems

Are you ready to become a word problem detective?

Welcome students and introduce the exciting topic of solving multiplication word problems. Ask if they've ever had to figure out how many items they needed for a party or how much something would cost if they bought multiple.

What's the Problem?

Word problems help us use math in the real world!

They tell us a story and ask us to find a number.

Today, we'll learn to solve them like pros!

Explain that word problems help us use math in real life. Give a quick example of when they might use multiplication without realizing it (e.g., buying 3 packs of stickers with 5 stickers each).

Our Strategy: C.U.B.E.S.

C - Circle the important numbers

U - Underline the question

B - Box any math action words

E - Evaluate and set up the equation

S - Solve and check!

Introduce the C.U.B.E.S. strategy. Explain each step clearly and briefly. Emphasize that this is a tool to help them break down problems.

Let's Practice Together! (Problem 1)

Mrs. Smith bought 4 boxes of crayons. Each box has 8 crayons. How many crayons did Mrs. Smith buy in all?

Present a simple word problem for guided practice. Go through each C.U.B.E.S. step with the students, asking for their input.

Let's Practice Together! (Problem 2)

There are 5 rows of chairs in the classroom. Each row has 6 chairs. How many chairs are there altogether?

Continue with another guided practice problem. Encourage students to lead the C.U.B.E.S. steps.

Your Turn! Independent Practice

Time to put your C.U.B.E.S. strategy to the test!

Work on your Multiplication Word Problem Worksheet.

Remember to show your work!

Explain that it's now their turn to try. Briefly reiterate the C.U.B.E.S. strategy and encourage them to use their worksheets. Remind them to show their work!

You've Conquered!

Great job today, Multiplication Detectives!

  • What was one new thing you learned?
  • How will you use the C.U.B.E.S. strategy?

Keep practicing your multiplication skills!

Conclude the lesson by asking students to reflect on what they learned. You can pick one problem from the worksheet to quickly review as a class. Remind them how useful these skills are!
