This game is intended to help you visualize what is going
on with fraction division . If you get lost at
any point in the program, you can scroll down the window for instructions.
You will be shown a point of the number line for which you
must enter the corresponding fraction. You must enter
the fraction in the form shown in the pictures below. The picture on the left
shows how you would enter and
the other picture shows 5. (Why is this 5?)
Pretend that you were given these problems on the
Create drawings for each problem to imitate what the
would show. Explain in a sentence why the answer makes sense.
For example, the picture at right illustrates
makes sense because six one-fourths fit into .
Most of you remember the “flip and multiply” algorithm for
Why does this method work ? The purpose of this part of the
lab is to develop an understanding of why “flip and
Wanda the Witch had 3 pounds of candy corn to give away at her Haunted House.
She decided to make 1/4 pound
bags to give away. How many bags of candy corn could she make?
(a) Let’s represent this story with a picture and use the
picture to de termine the
Each rectangle represents 1 pound of candy corn. I divided
each pound into 4 equal regions to represent
1/4 pound bags. Now I can solve the problem by counting the number of 1/4ths in
the 3 pounds. There are 12 1/4-pound bags in the 3 pounds of candy corn.
(b) Let’s write a division statement for this problem and
connect each number to the
Division statement: 3 ÷ 1/4. The 3 represents the whole: 3 pounds. The 1/4
represents the size of the
part that I am repeatedly taking away: 1/4 pound bags. So 3 pounds ÷ 1/4
pounds per bag = 12 bags.
(c) Let’s write a multiplication statement for this
problem and connect each number to
Multiplication statement: 3 x 4. The 3 represents how many pounds of candy corn
Wanda has. The 4
represents the number of 1/4 pound bags that are in each pound of candy corn.
So 3 pounds x 4 bags per pound = 12 bags.
(1) A turtle undertakes a journey of 2 miles. Each day,
the turtle travels 1/5 of a mile. How many
days will it take the turtle to finish the journey?
(2) The Habitat for Humanity team can build 2/3 of a house
in one day . They plan to build 4
houses. How long will it take to finish all 4 houses?
(3) The vet has a new bottle containing 4 ounces of
special medicine. She will be administering
several doses of this medicine to her cats and dogs. Each dose is
ounces. How many doses
are in the bottle?
Look back at your solutions to the problems above. Write
an explanation for why it makes
sense to “flip and multiply” when you do fraction division.
