Angela needs to solve a math problem given to her by her teacher involving finding the shortest length each piece of wood can be cut from three pieces of wood of lengths 2dm, 4dm, and 6dm. The problem can be solved by finding the least common multiple (LCM) of the numbers using continuous division. Students will be divided into groups to work on finding the LCM of different number sets using the division method.

2. “Jollibee or McDo”
Mechanics:
a. The whole class will participate in the activity
b. Flashcards with written numbers will be placed
in the pocket chart.
c. The pupils will flap their hands like a bee, if the
number is PRIME and do the McDo sign if the
number is COMPOSITE.

3. What is the value of good education and
study habits?

4. Angela needs to attend
Enrichment activity in
Mathematics. She goes to the
library to attend solve the
activity given to her by her
teacher.

5. Angela needs to solve the problem.
Elmer wants to cut as many pieces of
wood of equal lengths from three pieces
with lengths 2dm, 4dm, and 6 dm. What is
the shortest that he could cut each piece?
How will you solve for the answer to the
problem?

6. Understand:
What does the
problem?
The longest that he could
cut each piece.
What facts are
given?
2 dm, 4 dm, 6 dm of wood.
Plan
How will you
solve the
problem?
By finding Least Common
Multiple (LCM)
You can use the 4 - step plan in solving
for the answer.

7. Solve:
How is the solution
done?
By listing the factors
2: 2,4,6,8,10,12,14,16,18,20
4: 4,8,12,16,20
6: 6,12,18,24,30
LCM:
By division

2x 2x3=12
12 dm is the shortest cut can be
done in the wood.

8. Divide the pupils into teams. Let them
work on the problem by learning team.
Note: Solving this problem requires
finding the least
common multiple of numbers.
Let the pupils find the LCM of the
numbers using the method that they
know.
Group 1- 6,14
Group-2 -32,28
Group 3- 10, 15
Group 4- 81,9
Group 5- 12,14
