This lesson plan is for a 5th grade mathematics class. The students will learn to solve word problems involving the area of trapezoids and circles. They will practice mental math, drills, and reviewing formulas. Then the teacher will present sample problems for the students to work through using a four-step problem solving process. This involves understanding the question, identifying relevant facts, planning a strategy, solving using the strategy, and checking the answer. The students will then solve similar practice problems and problems applying the concepts. Their understanding will be evaluated through additional word problems to solve. For homework, students are assigned one final word problem to solve.

III. Learning Experiences
A. Preparatory Activities
1. Mental computation
A circular ground has a circumference of 45 m. What is its
diameter/radius?
2. Drill
 Have the students find the quotient of the following:
18 35 63 36
÷ 4 ÷ 5 ÷ 7 ÷ 9
3. .Review
 Ask the pupils: What are the formulas for finding the area of
a trapezoid and a circle?
B. Developmental Activities
1. Presentation

2.  Group the pupils into 4. Let the pupils solve the problem
below using the four step plan.
1. The circumference of a circular flower bed is 47.1 m. What is
its area? (Use 𝜋 = 3.14)
2. The area of a trapezoidal garden with the bases of 45 and 30
is 150 m2
. What is the value of height?
Understand:
-Identify the question.
-Identify the relevant facts
Plan:
- Choose a strategy
Solve:
-Perform the strategy.
Check:
-verify if the answer is correct.
2. Fixing Skills
 Solve these problems.
1. The circumference of a circular clock is 25 cm. What is its
area?
2. The area of a trapezoidal garden with the bases of 10 m and
20 m is 150 𝑚2
. What is the value of its height?
3. Generalization
 Ask the pupils: How do we solve problems involving areas of
trapezoids and circle?
 In solving problems involving areas of Trapezoids and
Circle. First, identify the question and relevant facts.
Second, use appropriate formula. Third, perform the
strategy and lastly, verify if the answer is correct.
4. Application
 The trapezoidal field has a circular fishpond surrounded by a
carabao grass. How many square meters of grass were used to
surround it?

3. 32 m
32 m
What is asked?
What are given?
What is the solution?
IV. Evaluation
 Read the problem carefully. (5 points each)
1. The circumference of a circular mirror is 75 𝑐𝑚2
. What is its
area?
2. The area of a trapezoidal ground with the bases of 9 m and 15 m
is 96 𝑚2
. Find the value of its height.
V. Assignment
 Solve this problem.
1. The living room of Mrs. Sola’s house is in the shape of a
trapezoid with one of the parallel sides 4 m long and the other 6 m
long. The distance across these sides is 7 m. What is the area of a
carpet that would fit the room?
