(ENGAGE) 1. Warm-Up: Revisiting Fractions (5-7 minutes)
A. Presenting
examples/instance Show the students a pizza visual (or real pizza
s of the new slices!) with some slices missing.
lesson
Ask:
“What part of the pizza is left?”
“What do we call these parts?”
Let students share their thoughts (no wrong
answers here—just get them talking).
Ask:
"What is a fraction? Can someone explain it in their
own words?"
"Can you give me examples of where we see
fractions in real life?"
Key Points to Cover:
A fraction represents a part of a whole.
Parts of a fraction: numerator (number of parts) and
denominator (total parts).

B. Discussing new 2.Visual Demo: Equivalent Fractions (5
concept and minutes)
practicing new
skills #1 Use visuals like fraction bars or a pizza chart to
demonstrate how fractions can look different but
represent the same value (e.g., 1/2 = 2/4).
Ask:
"Why do you think fractions like 1/2 and 2/4 are the
same even though the numbers are different?"
Key Points to cover:
1/2 is the same with 2/4 because we can simplify
2/4 by dividing it with 2.
C. Discussing new 3.Introducing Operations: Addition and
concept and Subtraction of Fractions (15 minutes)
practicing new
skills #2 Part A: Adding/Subtracting Fractions with the Same
Denominator
Example: 3/8 + 2/8 = (3+2)/8 = 5/8.
Explain:
When the denominators are the same, just add or
subtract the numerators.
Part B: Adding/Subtracting Fractions with Different
Denominators
Step-by-Step Discussion:
*Find the least common denominator (LCD).
*Convert fractions to have the same denominator.
*Add or subtract the numerators.
*Simplify the result, if necessary.
Example for Discussion:
"How do we solve 1/4 + 1/3?"
Solve it together:
LCD = 12 → 1/4 = 3/12, 1/3 = 4/12.
Add: 3/12 + 4/12 = 7/12.
Key Question:
"Why do you think finding a common denominator
is important?"

Work through the first two problems as a class.
Let students work on the next two in pairs, then
share their answers.
E. Finding Activity: Paper Pizza Race Activity
practical/application of
concepts and skills in Use paper cutouts of pizzas divided into slices.
daily living. Give students problems like "Combine 1/4 of a
pizza and 3/8 of another pizza" or "Divide 3 pizzas
equally among 4 friends."
Game Instructions:
Form Teams:
Divide the class into small groups (3-4 students per
team pero depende sa kadaghanon sa students).
Solve Fraction Challenges (15-20 minutes):
Teams draw a task card and solve the problem
using their paper pizzas.
Example Task:
“Add 2/8 and 3/8 of your pizza. What fraction of the
pizza is this?”
Teams physically combine slices or remove slices
to show their answer.
Earn Points:
First team to have correct answer will earn 1 point.
The first team to have 5 points will be determined
as winner followed by the second most highest and
third and so on.
