Objective
By the end of this lesson, you will be able to apply arithmetic concepts to build a wood fort.
Materials and Prep
- Wooden planks
- Measuring tape
- Pencil and paper
- Calculator (optional)
- Prior knowledge of basic arithmetic operations (addition, subtraction, multiplication, division)
Activities
-
Measure the available space for building the fort using the measuring tape.
-
Calculate the total area of the fort's base by multiplying the length and width of the space.
-
Determine the number of wooden planks needed for the fort's walls by dividing the total perimeter of the base by the length of each plank.
-
Add the number of planks required for the walls to the number of planks needed for the roof. Calculate the total number of planks needed.
-
Estimate the total cost of the wood by multiplying the cost per plank by the total number of planks needed.
-
Draw a scaled diagram of the fort, representing the measurements and layout.
Talking Points
- "To build a wood fort, we need to carefully plan and measure the available space."
- "By multiplying the length and width of the space, we can find the total area of the fort's base."
- "To determine the number of planks needed for the walls, we divide the total perimeter of the base by the length of each plank."
- "Adding the number of planks required for the walls to the number of planks needed for the roof gives us the total number of planks needed."
- "By multiplying the cost per plank by the total number of planks needed, we can estimate the total cost of the wood."
- "Drawing a scaled diagram helps us visualize the measurements and layout of the fort before building it."
