2. ESSENTIAL QUESTIONS How can we determine how much someone gets in a fair-share situation if the fair share is less than 1? How can we determine how much someone gets in a fair-share situation if the fair share is less than 1? How can we determine how much someone gets in a fair-share situation if the fair share is between two whole numbers? How can we determine how much someone gets in a fair-share situation if the fair share is between two whole numbers? Explain how fractions can be used to illustrate fair shares. Explain how fractions can be used to illustrate fair shares.

3. Sharing Candy Bars Work with a partner to solve this problem. Make sure to write your answer and how you determined it in your notebook. A fifth grade class is split into four groups. Students in the class brought in candy bars for a fraction celebration. When it was time for the celebration, the candy bars were shared as follows: The first group had 4 people and shared 3 candy bars equally. The first group had 4 people and shared 3 candy bars equally. The second group had 5 people and shared 4 candy bars equally. The second group had 5 people and shared 4 candy bars equally. The third group had 8 people and shared 7 candy bars equally. The third group had 8 people and shared 7 candy bars equally. The fourth group had 5 people and shared 3 candy bars equally. The fourth group had 5 people and shared 3 candy bars equally. When the celebration was over the children began to argue that the distribution of candy bars was unfair, that some children got more to eat than others. Were they right? Or, did everyone get the same amount?

4. Some strategies Cutting each candy bar into a familiar fraction first, such as halves or thirds, then cut the leftovers into slivers. What do you name the pieces (what is 1/5 of 1/3? for example) Cutting each candy bar into a familiar fraction first, such as halves or thirds, then cut the leftovers into slivers. What do you name the pieces (what is 1/5 of 1/3? for example) Cutting each candy bar into a number of pieces that is the same as the number of people in the group. For example, if 4 candy bars are shared among 5 people, each of the 4 candy bars is cut into 5 pieces. So, 1/5 of each candy bar goes to each of the 5 people. Does the size of the whole matter? Everyone gets 4/20 of the pieces, but this is also 4/5 of one candy bar. Cutting each candy bar into a number of pieces that is the same as the number of people in the group.

5. ESSENTIAL QUESTIONS Revisited Answer the essential questions in your notebook. 1. How can we determine how much someone gets in a fair-share situation if the fair share is less than 1? 2. How can we determine how much someone gets in a fair-share situation if the fair share is between two whole numbers? 3. Explain how fractions can be used to illustrate fair shares. Also answer the questions below: 4. Justify and explain why your collection is less than one whole, equal to one whole or 5. more than one whole. 6. How far away from a whole is your fraction? How do you know? 7. What if the pieces were halves instead of eighths? How would your answer change? 8. Did you develop a shortcut to find your answers? 9. Did you identify any patterns or rules? Explain!
