Landmarks: Mean, Median, Mode - Grade 4

Interpreting data on graphs is usually referred to as looking for landmarks. We usually look for the following information: Maximum—what was the highest number in the data? Minimum—what was the lowest number in the data? Range—What is the difference between the maximum and the minimum? Mean—This is another word for AVERAGE, which is found by adding all of the data and dividing by the number of entries. Median is the number half-way between the highest and lowest number in the data. Mode is the number that appears most often in the data.Please see below for a selection of Leveled Lessons for Below Level (basic), and/or On Level (median), and/or Above Level (competent) students.

Teaching Tips

Help students learn to interpret information on a graph by conducting many whole group activities before you expect them to determine these things independently. As students enter the classroom, have them sign their names on the chalkboard beside the letter that tells how many letters are in their name. Thus, Mary will write her name beside the 4.

Have the class help you create a whole-class graph to show this information. Find the maximum, minimum, range, mean and mode according to the descriptions above. To find the minimum, have the students write down every piece of data, and to write those in order.


A small classroom might have had this data about the numbers of letters in student names: 3, 4, 4, 4, 5, 5, 6, 6, 7, 7, 8.

It is better to write these in vertical, rather than horizontal form.

Then have students start crossing off numbers--first the top, then the bottom, the next top, and the next bottom. The number they are left with is the median number.
