    Overview:  Multiplying and Dividing Fractions 

    Estimated Time: Approximately 30 minutes

    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.

     

    Tasks:

    1. Continue recording the daily temperature on your chart.
    2. Self-made Questions:
      • 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.
    3. Catering Company Activity:
      • Activity: Imagine you are the owner of a catering company. Choose a recipe that you will make for a party.  Consider a recipe that you would enjoy eating. 
        • Your customer just called and said they need to triple the amount of people at the party.
          • Multiply each of the ingredients by 3 and rewrite the ingredients list.
        • Your customer just called and said that five times as many people are coming to the party.
