ACTIVITY
Get a piece of paper and a pen.
Do all of the directions given by writing them down
in your paper. There are 16 directions you need to
follow in 2 minutes ONLY so you must hurry!

1. Read all the 16 steps first before doing or
writing anything.
2. Write your surname in the center of your
paper.
3. At the top of your surname, write numbers
1 to 10.
4. Draw three hearts at the top of number 3.
5. Shade the second heart.

6. Encircle all even numbers (2, 4, 6, 8, 10).
7. At the bottom of your paper, write your first
name.
8. Fold your paper in half. (making 2 columns)
9. Open your paper and wave to the teacher.
10.Draw a triangle at the back of your paper.

11.Put an “X” in the center of the triangle.
12.Use the tip of your pen to poke a hole in
your paper straight through the “X” mark.
13.Tap your desk 10 times.
14.Write your teacher’s name anywhere in
the paper.

15.If you have carefully done all steps, say
“I’M DONE!”
16.Now that you have finished reading
everything, do only steps 1 and 2.

• Factoring is the process of
finding the factors of an
expression.
• It is the reverse process of
multiplication

CMF is like splitting an expression into
two factors, obtaining a common factor
from all terms.
ab + ac + ad
Common Monomial Factoring

1. Find the GCF of the numerical
coefficients; Find the variable with the
least exponent in each term of the
polynomial.
2. Divide each term in the polynomial by
the obtained GCF. The resulting
quotient is the other factor.
Steps in CMF:

Factor 12x3y5 – 20x5y2z .
4x3y2
GCF:
1. Find the GCF of the numerical coefficients; Find the variable with the least
exponent in each term of the polynomial.
2. Divide each term in the polynomial by the obtained GCF. The resulting
