Designed
by: Margaret Knight School:
Gibbes Middle School
Grade
Level: 6th
Subject(s): Math
Core
Curriculum Objective(s): Student will describe and
calculate the mean, median, and mode as measures of
central tendency and determine their meaning for a set
of data. (6SP1-7)
Overview:
Students will measure the heights of a group of four
and then work out mean, median, and mode and explain
how these statistics might be used to demonstrate the
average height for 10-12 year old.
Focus/Essential
Question(s): How can you find the mean, median,
and mode of the heights of 6th grade students?

Culminating
Assessment: Student will record the heights of
students in their group, find the mean, median, and
mode of the heights, and combine this with data
collected from whole class to make a display.
Instructional
Activities: Teacher will review mean, median, and
mode.
