Overview:  Multiplying and Dividing Fractions

Estimated Time: Approximately 30 minutes

Explanation:   Today you will review how to multiply and divide fractions.  Then, you will apply your knowledge.

Things to know:

• Fractions have a numerator (top number) and a denominator (bottom number).
• How to multiply fractions:
• First, multiply the numerators.
• Then, multiply the denominators.
• Simplify the answer, if you are able.
• How to divide fractions:
• Write the division problem horizontally.
• Keep the first fraction
• Change the division sign to a multiplication sign
• Flip the second fraction.
• Then, multiply the fractions and simplify, if needed.
• There are no pre-made worksheets for today.

1. Continue recording the daily temperature on your chart.
• You will need your number cards for this activity.
• Take a pencil, pen, straw, etc. and place in in front of you to make a horizontal line. Place another pencil, pen, marker, straw, etc. and place in in front of you to make another horizontal line.
• Flip over one number card and place it above one of the horizontal lines. Flip over a second number card and place it below one of the horizontal lines.  Continue until you have two fractions.
• Multiply or divide the fractions.
• Repeat 8 times.
• You may record your fraction multiplication and division in your composition book or on a separate sheet of paper.  There are no worksheets for today.
