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. This lesson is meant for 4th grade math. Check out also my other 4th grade math videos at www.mathmammoth.com/videos/grade_4/math_videos_4th_grade.php (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.)
