Vitamin C Servings
The serving size for a toddler’s daily vitamin C is ¾
cup of orange juice. If there are 2 ¼ cups of
orange juice, how many servings of vitamin C are
there for a toddler?
1. Write the problem as a division problem.
2. Use a picture, fraction circles or a number line to
solve.
3. Use the algorithm to solve. Compare your
answers.

Tic-Tac-Toe
Directions:
1. Pair up with a classmate.
2. Determine who will be “x” and who will be “o.”
3. The “x” person will solve the first problem, and then have the
“o” person check it. If it was solved accurately, then the player
gets to take a turn on the board. If not, the player loses a turn.
4. Then the “o” person will solve the next problem, have the “x”
person check it, and take a turn. If the player does not solve it
correctly, that player loses a turn.
In your own words…
In your own words, write the steps for dividing a
fraction by a fraction.
What do you do when you have a mixed number
divided by a fraction? Or a mixed number divided
by a mixed number?
