Drawing a bar graph from the given data - 4th grade math

I show how to make a simple bar graph from numerical data of quiz scores. First, we make a frequency table, checking how many students got a quiz score of 5, 6, 7, 8, 9, and 10. Then I draw the bar graph. Lastly, we go through some questions concerning the graph.

(Note: the data in this situation is discrete, not continuous; in other words, the quiz scores cannot be 5.5 or 7.8; therefore, a bar graph is appropriate instead of a histogram.).
