TOPIC:

All students will know:

MATH
mode are described as measures of
center.
Understand that mean, median, and
mode are three of the various ways that
data can be described or summarized.
Understand that mean as fair share is
described as equally dividing the data set
or the data set has already been divided
equally.
Understand how to find the mean,
median, and mode of a set of data as
measures of center.
Understand values in the context of other
characteristics of the data in order to
best describe the results.
DEMONSTRATORS
What do your students need to be able to DO?
ASSESSMENT
How will you assess what
your students ALREADY
KNOW, and assess WHAT
THEY’VE LEARNED?
ACTIVITIES
HOW will you teach it?
Students will:
 Describe and find the mean, median, and mode
of a group of numbers representing data from a
given context as a measure of center.
 Describe mean as fair share.
 Describe and find the range of a group of
numbers representing data from a given context
as a measure of variation.
 Describe the impact on measures of center when
a single value of a data set is added, removed, or
changed.
Pre- test using a data set
problem.
Have students’ document
understanding.
Post- test using the same
data set to check for
understanding after your
lessons.
Create a school grade sheet for each
student in your class and have them
find the mean, median, mode and
range of the data set. After practicing
with these fictitious numbers give each
student their own scores for the six
weeks. Then allow students to
calculate their grade average using the
mean. Have a conversation about the
use of median, mode and range to
calculate student scores, what if we
used one of these methods instead to
calculate students grade average each
six-weeks.
DIFFERENTIATION
How will you meet the needs of all students?

TEACHER NOTES:
Provide students data sets in the form
of bar graphs, stem and leaf plots and
pie charts. Then allow students to
work in partner groups to interpret the
data, and then they will order the
data. Using the information they will
calculate Mean, Median, Mode and
Range for this data without the use of
a calculator. Then check the work
with a calculator.

The most important things to understand are the definitions of each
mean, median, mode and range. A good note is to make vocabulary
cards students can carry with them to practice these math
definitions.
