1. Topic-
|
| Prime Factorization and Greatest Common Factor |
| |
|
2. Content-
|
| Prime Number, Common Factors, Greatest Common Factor, Multiples,
Factor Tree |
| |
|
3. Goals: Aims/Outcomes-
|
| The student will have the ability to factor a group of numbers into
it's prime components and from that find the greatest common factor. |
| |
|
|
4. Objectives-
|
1. The student will understand and recognize primes.
2. The student will be able to breakdown two or more numbers into
its prime factors. N.MR.05.01, N.FL.05.05, N.MR.05.07(Core)
3. From a group of Prime Factors the student will be able to find
the Greatest Common Factor. N.FL.05.05, N.MR.05.07 |
| |
|
5. Materials and Aids-
|
| Marker and Whiteboard (Pencil and Paper if not), |
| |
|
6. Procedures/Methods-
|
|
A. Introduction-
1. The students will play Multiplication/Division around the world
in order to peak interest and review math facts
2. The teacher will discuss prime numbers with students |
| |
|
|
B. Development-
1. The teacher will model how to create a factor tree and list Prime
Factors
2. The teacher will show how the students can use the Prime Factors
to find the Greatest Common Factor
|
| |
|
|
C. Practice-
1. The students will practice creating factor trees and listing
primes
2.The students will practice finding the greatest common factor on
a whiteboard
|
| |
|
|
D. Independent Practice-
The students will complete a Greatest Common Factor worksheet
|
| |
|
|
E. Accommodations (Differentiated Instruction)-
| The teacher can also show how to find the greatest common factor
through listing(although not recommended because of the chance students
miss factors) |
| |
|
|
F. Checking for understanding-
| The worksheet along with teacher input will act as the assessment
for understanding |
| |
|
|
G. Closure-
Discuss with students how knowing the greatest common factor will
help in other aspects in math(prompt fractions).
