16.) Determine if outcomes of simple
events are likely, unlikely, certain, equally
likely, or impossible.
Lesson Objectives:


Students will be able to
demonstrate their knowledge of
the outcomes of simple events.
Students will be able to
demonstrate the appropriate
vocabulary used when
determining outcomes.

6.) Solve problems, including word problems, that
involve addition and subtraction of four-digit
numbers with and without regrouping.
• Estimating sums and differences of whole
numbers by using appropriate strategies such as
rounding, front-end estimation, and compatible
numbers
• Adding and subtracting decimals and money
amounts

Today’s lesson will be focusing on
probability. To begin ask students what is
probability? Have student’s think-pairshare with a neighbor. As a class discuss
the meaning of probability. As students
express their ideas create a web about
probability on chart paper to give students
a visual. After completing the probability
Students will demonstrate their
knowledge of subtracting of three to four
digit numbers with regrouping.

Whole Group
Today we will be working on subtracting four digit
numbers with regrouping. Before we begin
students will be broken up into pairs. These pairs
will be preselected. Students will scattered around
the room. Each pair will be given a bag of with
triple and quadruple subtraction problems inside of
it. Not only will students are solving these problems
they will be solving them through hangman. The
rules are a student has to get six problems in a row
correct. As students get a correct answer they are
able to add a body part to their hangman. Students
web begin the Probability PowerPoint.
This PowerPoint will define probability,
discuss vocabulary, give examples, and
group practice. When defining probability
refer to the web to determine if students’
ideas were accurate. When discussing the
vocabulary ask students first what they
think about the meaning of the word
before revealing the true definition. After
the vocabulary begin showing examples.
When working the example problem
complete them as a class. Question the
student’s before giving the correct
answer. Answer any questions before
moving on to group practice.
Small Group
The group practice portion of the
PowerPoint explains the group activity we
will be completing today. The slides will
give directions for the activity and an
example. The first activity has students
broken up into small groups, not based on
ability. Each group will be given a
probability worksheet, brown bag, and a
bag of candy. Students will have to read
the different situations/problems on their
worksheet in order to determine the
probability of each of the situations. Make
sure students include their name and
group members on their worksheet they
will be turning in for a grade.
Math Centers:
Students are given a math work plan at
the beginning of each week. This plan
gives detailed directions, explanation, and
point descriptions for each of the four
centers they have to complete each week.
This week’s copy is attached to the lesson
plan. Students must sign the bottom of the
work plan saying that they agree with the
directions and that they will complete the
assignments. This week there are four
centers:




M&M Probability Center
Free the Animals Center
Blow Pop Probability
Technology Center
will continue to play until a player completes a full
body. A body includes a head, body, two arms, and
two legs. Students will alternate turns so that no
time is wasted. Monitor students as they work in
pairs.
 During this small group time all three
fifth grade teachers divide their students
up into their target need areas. Each
teacher is assigned a target skill. Mrs.
Barksdale, Mrs. Fisk, and I will be
trading students. Mrs. Collins will be
assisting.
Power Math (Whole Group)
Before beginning power math pass out
the class set of power math journals.
These journals are found in a basket on
the book shelf. Make sure students write
the date at the top of their paper. Students
will be given ten problems based on the
Alabama Course of Study standards to
complete. Students must write the
problem and show their work to receive
full credit on this assignment. This work
should be done independently NOT in a
group. When everyone is finished take up
the power math journals and return them
all to the basket on the book shelf. These
may or may not be graded at a later date.
Encourage students to put forth their best
effort. *Problems are attached.

Probability Work Plan
M&M Math Problem Center- Who does not like playing with M&M’s? Students will place M&M
markers on the numbers 2-12 on the number line. Students may place one M&M marker on each
number or place several on some numbers and leave other numbers blank. After your board is set
up toss two 6-sided dice, find the sum, and remove an M&M marker from that number, if there is
still one. Repeat these steps until the first player to remove all markers wins the game. Make a
chart and record all of your rolls. At the end of this center make sure to take a pack of M&M’s
from the basket.
Free the Animals Center- Who can free the animals first? Students will set up their board,
select their playing pieces, and begin playing. Place the animals on all of the cages. Students must
use the recording sheet to record how many animals they placed in each cage. The first player
must roll the dice twice and calculate the difference and free one animal from that number cage,
if there is an animal in the cage. Repeat these steps. Play until a player releases all of their
animals. Create a chart and record results of each roll. The first person to free all of their animals
wins the game!
Blow Pop Probability- What are the chances of getting a piece of candy after this center? Well,
play the game and we will find out. There should be two brown bags in the basket. One bag is
filled with blow pops the other empty. Students will make a chart and count how many of each
flavor is in the bag while emptying them into the other brown bag. Each student will then pick
their favorite flavor. Make a graph, include all flavors, and decide the probability of pulling your
favorite flavor and each different flavor of sucker out of the bag. If everyone completes the entire
center then everyone can have a sucker. Enjoy!!
Technology Center- Log on to the computer and go to http://ia.usu.edu/index.php. This web
address will take you to Miss Goodwin’s site. The student password is Goodwin. Play all of the
games available on the site. Afterwards write a paragraph about what you learned from at least
one of the games played.
