Procedures
PreTest
Students will be administered a pretest pertaining to matrices. (See attached)
Anticipatory set
Students will name real world situations where items are arranged in rows and columns.
Some examples include grocery items, cars in a parking lot, flight arrivals/departures, spreadsheets, desks in a classroom,
and city streets.
Teacher Input
The teacher will introduce new terminology including the following:
matrix, element, row, column, determinant, scalar, dimension, inverse matrix, and zero matrix.
While introducing the terms the teacher will design a KWLchart on the board. The students will create their own charts
and complete them.
The teacher will then discuss the terms, allow students to put the definitions into their own words, and record that definition
into their notes. They may also draw and label the parts of a matrix.
After the students have a thorough understanding of a matrix, they will be asked to stand and arrange their desks in a
three by four rectangular array. They can decide what direction they want their desks to face.
The teacher will give pointers such as "Row across the lake" to aid the students in remembering the difference
between rows and columns. The teacher may also tell them to envision a plantation home with big columns standing tall. Students
may have input on ways to distinguish between rows and columns.
After the seats are arranged, the teacher will ask for a volunteer to choose any seat and have them to sit in it then
ask the class to identify his/her position.
The teacher will choose different students and repeat this action a couple of times until each student can identify their
location within a matrix. The teacher can also tell the student where to sit. For example sit in (2, 3) means second row,
third column. When done, the students will return to their assigned seats.
Modeling
The teacher will demonstrate how to add and subtract matrices using a visual representation (chart) and the board. Then
the teacher will illustrate and compute examples of matrices on the board.
Guided Practice
The teacher will discuss how the dimension of the matrices must match in order to add or subtract elements.
[ A ] = 2 3
4 5
[ B ] = 3 6
4 1
0 7
[ C ] = 1 4
6 7
[ D ] = 1 5
6 10
3 4
The teacher will work problems on the overhead projector, while the students work along.
Compute the following:
[ A ] + [ C ] [ B ] + [ D ] [ A ] + [ B ]
The teacher will explain that this can't be done because the dimension of the matrices must match in order to add elements.
The teacher will also explain that the commutative property of addition holds true for matrices.
Then, they will work:
[ A ]  [ C ] [ B ]  [ D ] and show that matrix subtraction is not commutative.
The teacher will have selected matrices already prepared. Using their own personal dry erase boards, students will practice
computing matrices of their own. Students will be allowed to use their graphing calculators to check their work.
Independent Practice
The students will use matrices to organize and keep track of numerical information, and will apply addition and subtraction
of matrices in a meaningful way.
Students will formulate addition and subtractions matrices of their own and make the necessary computations.
Students will then write a short written report of their matrices and their calculations, using clear notations and labeling
what they represent.
Check for Understanding
The teacher will constantly check for understanding from student feedback, facial expressions, observations, and students'work
samples.
Closure
Using their math journals, students will list 3 things that they are square about the lesson, 2 things that are circling
around their minds about the lesson, and 1 thing that is not clear about the lesson (These questions were taken from the What's
Circling Around Worksheet.)
Technology
The students will create a spreadsheet using Excel, which is an applied matrix.
Diversity
The teacher will use differentiated instruction, clinical teaching, pair and share and Communicator boards.
Diversity will be addressed according to the needs of the class.
Reteaching
The teacher will illustrate two matrices on the board, using a different color for each set of matrices. Then, she/he
will demonstrate how to add the matrices. The teacher will then illustrate how to subtract the matrices.
Using dry erase boards, the students will add and subtract matrices.
Enrichment
Students will compute the following types of matrices: addition, scalar multiplication, multiplication, determinants,
and inverses of matrices.
Homework
Students will add the following matrices:
[A] 5 4 [B] 2 3
9 7 + 0 1
[C] 17 19 + [D] 36 30
32 25 21 14
Students will subtract the following matrices:
[A] 2 8 [B] 7 4
0 6  0 3
[C] 12 23 [D] 28 36

Procedures
Anticipatory set
The teacher will create a real life story problem:
Suppose Joe earned three times as much money as Marty during the summer. Together they earned $210. How much did each
person earn?
Volunteers will go to the board and write the steps they took to arrive at the answer. The students who arrived at the
answer in another way may show their procedures as well.
Teacher Input
The teacher will give an explanation of what a scalar is and its purpose. In doing so, the teacher will explain what
matrix multiplication is by writing a variable (x) outside of a matrix and demonstrating how the scalar multiplies each element
within the matrix:
a [c d e f] = [ac ad ae af ]
The teacher will then explain and demonstrate how the scalar (a) is multiplied throughout and is similar to the distributive
property. A distributive property chart will be displayed.
The teacher will repeat the process using a scalar variable and numerical elements:
a [2 4 3 8] = [2a 4a 3a 8a]
Students will take notes.
Using magnetic numbers, the students will create their own scalar numerical matrices. When done, they will swap their
matrices with their classmates and then compute the matrices.
Modeling
The teacher will illustrate problems on the board taken from the Matrix Activity Sheet. The students can volunteer to
go to the board and compute the problems. They will be allowed to use their graphing calculators to check their answers.
Guided Practice
The teacher will create a problem to which the students can relate for better understanding:
My aunts, Betty, Martha and Alice are arguing about their favorite fast food restaurant. They decided that they would
each purchase the same number of items from the top three picks and see which one was cheaper.
The teacher will ask the following question: how much is Clarisse going to spend at BunKing?
The teachers will aid the students in computing the matrix multiplication. The multiplication would represent the amount
each aunt would spend at each of the three eating places.
Independent Practice
The students will look at the process of multiplying a scalar by a matrix and then a matrix times a matrix.
Using the magnetic numbers and letters, the students will create their own scalar numerical and variable matrices. Upon
returning to class, the students will swap their matrices with their classmates and then compute the matrices.
Check for Understanding
The teacher will constantly check for understanding from student feedback, facial expressions, observations, and students'work
samples.
Closure
Using their math journals, the students will write and explain the process of multiplying matrices. They will also indicate
one real life example where matrices can be applied.

they will use their graphing calculator to compute the necessary operations.
Diversity
The teacher will use differentiated instruction, clinical teaching, pair and share and Communicator boards.
Diversity will be addressed according to the needs of the class.
Reteaching
The teacher will illustrate two matrices on the board, using a different color for each set of matrices. Then, she/he
will demonstrate how to add the matrices. The teacher will then illustrate how to subtract and multiply the matrices.
Using dry erase boards, the students will add, subtract, and multiply matrices.
Students will use numbers cubes to produce the following matrices: 4 X 2 6 X 3 2 X 4
They will roll the cube twice with their left hand. If the rolls produce a 3 and a 6, the students will write 36. They
will continue the process. Then, they will do the same with their right hand. The students will then label the columns left
hand, right hand, and both.

Procedures
Anticipatory set
The teacher will create a real life story problem:
Mr. Ojero is ordering a new car. He can choose from 5 models, 12 exterior colors, and 9 interior colors. How many combinations
of models, interiors, and exteriors are possible?
Volunteers will go to the board and write the steps they took to arrive at the answer. The students who arrived at the
answer in another way may show their procedures as well.
Teacher Input
The teacher will review scalar multiplication by providing examples on the board. The teacher will demonstrate how to
multiply a matrix [A] times a matrix [B].
The teacher will emphasize the importance of the dimensions. The column of the first factor must match the number of rows
in the second factor.
The students will use color pencils to differentiate between columns and rows.
The teacher will work examples using varying dimensions of matrices.
The students will compare and contrast adding and multiplying matrices using a 2 X 3 matrix. They will do so by constructing
a poster in which they display the similarities and differences between the two. They will illustrate the steps required to
solve addition and multiplication matrices. They will also provide examples.
Modeling
Using the overhead projector, the teacher will provide examples of how to multiply matrices. In doing so, she/he will
apply what is being taught to the real world.
Guided Practice
The teacher will facilitate as the students work in groups to compete in multiplying matrices. The students will be provided
note cards with different problems written on them. The same number of note cards will be placed in each box. There will be
a box for each group. The first member of each group must select a card randomly from the box and turn the card over at the
same time. Next, the two students will race to compute the problem. Whenever they finish, the next person in their group will
draw a card from the box and the cycle will continue until all the students in a group has had a turn and completed their
problem. Whichever team finishes all their problems will receive a prize (notebook, pencil, eraser, and pen for each member
of the team).
