Motivation What do you think a graph is? A graph is visual representation of the data. Can you tell me the names of the different types of graphs? bar, double bar, pie chart/circle graph, line, etc. Why do you think information is often presented in graphs instead of just in a list or table? Graphs make it easier to compare different data.

What color did you predict would have the most? Answers will vary.

What color did you predict would have the least? Answers will vary.

Do you believe the bar graphs were the best graphs to use to represent your data? Why or why not? Answers will vary.

What other type(s) of graph(s) might have been useful to make? Pie chart/circle graph

After comparing your predictions and graphs with the actual numbers, were your predictions supported? Explain. Answers will vary.

In looking at the bar graph, what color actually has the highest number? Answers will vary.

In looking at the bar graph, what color actually has the lowest number? Answers will vary.

No, to tell percentage of each color use a pie chart/circle graph. Can you easily tell from either bar graph the percentage of each color in the bag? Explain. No, to tell percentage of each color use a pie chart/circle graph.

What would you use a pie chart for? Pie charts/circle graphs are used to show percentage or proportional data.

What would you use a line graph for? Line graphs are used to show changes over time.
