This lesson plan is for a 5th grade mathematics class. The objectives are for students to solve word problems involving the volume of prisms, write formulas for finding the volume of cubes and rectangular solids, and develop patience when solving word problems. Students will practice measuring and calculating the volume of objects. They will then solve word problems to find the volume of a swimming pool, aquarium, and rectangular box. Students will generalize how to find the volume of cubes and rectangular prisms. An evaluation involves reading problems and calculating volumes of a sewing box, gift box, and swimming pool. Students are assigned a homework problem calculating the number and total volume of boxes donated as relief supplies.

III. Learning Experiences
A. Preparatory Activities
1. Drill
 Have the students measure the length, width and height and
find the volume of the foll0wing:
1. Cabinet
2. Drawer
3. Shoebox
4. Rectangular boxes
B. Developmental Activities
1. Presentation
 Have the pupils solve the problem below.
1. A swimming pool is 12 m long, 9 m wide, and 3 m deep. How much
water can it hold?
 What is asked?
 What are given?
 How will you solve the problem?
 What formula will you use? Write the equation
 Solve the problem and state the complete answer
2. An aquarium is 35 cm long, 25 cm wide, and 24 cm high is to
be filled with water. How many cubic centimetre will be needed?
3. The volume of rectangular box with a length of 6 cm, width of 3
cm is 54 𝑐m3
. Find the value of its height.

2. 2. Fixing Skills
 Find the volume of the cubes below.
3. Generalization
 Ask the pupils:
 How will you find the volume of a cube or rectangular prism?
IV. Evaluation
 Read, think and solve
1. Trixie’s sewing box is 6 dm long, 3.5 dm wide, and 4.3 dm high.
What is its volume?
2. A small gift box has these dimensions: L = 6.2 cm; W = 8 cm and
h = 3.2 cm. What is its volume?
3. The swimming pool when filled to capacity contains 240 cubic meter
of water. If it measures 8 m across, and has a depth of 2 m, how wide
is the pool?
V. Assignment
A. Read and Solve (10 pts, ½ crosswise)
1. The UES foundation donated boxes of canned goods to the typhoon
victims to the super typhoon Yolanda’s victims. The boxes were placed in
a container van. There are 6 layers of 5 boxes in each row. How many
boxes are there in all? What is the volume of the container van using the
boxes?
