Surface Area of Cuboid
Welcome
Welcome Math Class Students
We will learn how to find the surface area of a geometric shape
Build the space we will learn is Blocks
We will learn to use the 5E Learning Cycle model
Recall: Area of Rectangle (Engagement)
Area of Rectangle
Do you remember how to find the area of a rectangle? Write the formula for the area of a rectangle in the box below
Exploring Cuboid (Explore)
Lets Explore the Cuboid (Explanation)
1. Please rotate, zoom in, and zoom out the beam to get the overall beam visual
2. Move slider b from 0 to 1 to see how the process of laying the surface of the block into a net
3. Then close the block again
4. After that, display the d element so that you will see the color on each surface
5. Notice which sides are opposite each other.
6. Lay the surface of the block back by moving the slider b from 0 to 1
7. Rotate the block so that the nets appear from above
8. What do you see? Picture in the box below
What do you see? picture of the nets you see along with adjust the color and observe the size (Elaborate)
What you can conclude
After the activities above, what are your conclusions? Write below
