1. Topic


2. Content

Students will learn the definitions of mean, median, mode, and data.
Students will learn how to identify the mean, median, and mode is
in various exercises and examples 


3. Goals: Aims/Outcomes

1. 10.A.2b Using a data set, determine mean, median, mode and range,
with and without the use of technology
2. 10.B.2c Analyze the data using mean, median, mode and range, as
appropriate, with or without the use of technology
3. Also addresses 10.B.2a and 10.B.2b 


4. Objectives

The students will find the mean, median, and mode of a set of data



5. Materials and Aids


6. Procedures/Methods

A. Introduction
1. I will begin by reviewing what students learned from the lesson
before (67). I will display a word problem on the board and students
will be instructed to use any problemsolving strategy to solve.
2. I will begin each lesson with a problem of the day. I will write
it on the board and students are to complete it before each lesson.



B. Development
I will model throughout the lesson by use of examples and explanation
of the new information



C. Practice
1. I will guide the students through the lesson beginning on page
279. I will read the opening paragraph and present each new vocabulary
word as they appear
2. The mean, median, and mode will each be described
3. After reading the information in "Get Ready to Learn," students
will begin working on example 1 with my guidance



D. Independent Practice
1. After working example 1, students will move on to example 2 in
their textbook. This example will show them how to find the median
of the data
2. I will emphasize the importance of writing the numbers in order
before finding the median and point out that the middle number will
always have the same number of data values before and after it in
the list. I will also point out that the median does not need to be
part of the data set
3. I will then present them with two more examples in order to help
them further in finding the median
4. Students will then move on to example 3 and we will go over it
together. I will give them a hint at remembering what mode means.
Mode=the number you see the Most. HINT: MOde...MOst
5. Students will now take out their whiteboards and complete exercises
17
6. We will then move on to page 281 and do example problems from what
is given
7. After completing all practice questions, I will assess the students
by asking various questions relating to what we covered
8. Students will be given a worksheet to complete for homework 


E. Accommodations (Differentiated Instruction)
1. LD students will have their homework sheets read to them and
will be allowed extra time or help to complete them



F. Checking for understanding
1. I will check for understanding throughout the lesson through
the answers students give to my questions
2. I will also check for understanding through the answers they display
on their whiteboards
3. I will assess the students before passing out homework sheets by
asking them various questions relating to what we covered 


G. Closure
Students will be given a worksheet to complete as homework



7. Evaluation

1. Students will be informally evaluated throughout the lesson through
the answers they give to my questions and through their participation
2. Students will be formally evaluated on their homework assignment
