DIY Activity Ideas for Teaching Mensuration - Surface Area & Volume
Introduction:
Are you a high school teacher or homeschooling parent looking for engaging activities to teach mensuration concepts to your students? In this blog post, we will explore five hands-on DIY activities that will help your students understand surface area and volume. These activities are fun, interactive, and require minimal materials. Let's get started!
Surface area of solids:
Surface area of an object: It is the total area of the object’s faces and curved surfaces
Activity 1: Finding Surface Area with Foam Cubes
Materials Required:
Procedure:
- Provide each student with foam cubes.
- Instruct them to construct different shapes using the foam cubes.
- Ask students to find the total surface area of each shape they create.
- Encourage them to explain their calculations and discuss their findings as a group.
Activity 2: Finding Surface Area using NetsActivity 2: Finding Surface Area using Nets
Materials Required:
- Foam sheets
- Transparent sheets
- Transparent grid with 1 cm^2
Procedure
- Distribute foam sheets, transparent sheets, and transparent grids to students.
- Instruct them to fold the transparent sheets into square and rectangular shapes with lengths equal to the foam sheet shapes.
- Ask students to measure the surface area of the folded transparent sheets by placing them on the transparent grid.
- Guide them in calculating the surface area and comparing it to the actual foam sheet shapes.
NOTE: Height of the cuboid (4 x 4 x 3) is 4 cm (including 1 cm of base thickness)
Volume of Solids:
Amount of Space Occupied by an Object:
Activity 3: Finding Volume of Cuboids
Materials Required:
- Foam cubes or pieces
- Container from Activity 1
Procedure:
- Have students place the 1 cm^3 foam cubes or pieces into the container from Activity 1.
- Instruct them to determine the volume of the cuboids by counting the number of foam cubes or measuring the displacement of water.
- Encourage students to discuss the relationship between the number of cubes and the volume of the container.
Exercise: Find the Volumes of these Cuboids
Cuboid-1 :
- Length- 3cm
width – 4cm
Height – 5cm
Cuboid-2 :
- Length – 5cm
width – 10mm
height – 1m
Activity 4: Finding Volume of a Cylinder
Materials Required:
- Foam block pieces
- Cylinder container
- Water
- 5ml syringe
Procedure:
- Provide students with foam block pieces and a cylinder container.
- Instruct them to fill the cylinder container with water using the 5ml syringe.
- Guide students in placing the foam block pieces into the cylinder without overflowing the water.
- Ask them to measure the volume of the cylinder using the amount of water required to fill it completely.
Activity 5: Finding Volume of Irregular Shapes using Water and known volume objects
Materials Required:
- Irregular-shaped objects
- Water
- Known volume object
Procedure:
- Provide students with various irregular-shaped objects.
- Instruct them to fill a container with water.
- Now drop the known volume object and measure the volume
- Guide them in calculating the volume of the irregular shapes based on the water and known volume objects
