Materials:

• Multiply Fractions Lesson

• A few king size chocolate candy bars that you can break into equal size pieces

• Multiply Fractions Worksheet

Procedure:

1.  Warm-up: Bring in a few king size chocolate candy bars that can be broken into smaller equal size pieces. Ask students how they would split this chocolate into equal size portions. Ask students if they will have more and or less pieces when they break a large candy bar in half.

 

2.  Motivate the Lesson: Ask students if they have multiplied fractions before. Break the candy bar into unequal pieces and give the two pieces to volunteers. Ask the students if the unequal size pieces are fair. Explain that to be fair they need to use fractions to break the candy bar into equal size pieces.

 

3.  Proceed through the lesson with the “Question of the Day”. Use another candy bar and visually break the candy bar up based on solving fractions. Option - Reward participating students with pieces of chocolate.

 

4.  Verify that students can properly identify the numerator and denominator. Verify that they understand the three steps of fraction multiplication.

*Stress that you do NOT need a common denominator in order to multiply. Students tend to mix this up with addition & subtraction of fractions.

 

5.  Have students complete the How to Multiply Fractions worksheet for homework.
