Objective

By the end of this lesson, you will be able to apply arithmetic concepts such as addition, subtraction, multiplication, and division in a fun and engaging activity of building a car using LEGO.

Materials and Prep

• LEGO bricks
• LEGO car building instructions (optional)
• Paper and pencil for calculations

Prior knowledge of basic arithmetic operations (addition, subtraction, multiplication, and division) is recommended.

Activities

1. Choose a LEGO car design or create your own.

Start by selecting a LEGO car design from available instructions or create your own design using your imagination.

2. Count the number of bricks needed.

Count the number of LEGO bricks required to build your chosen car design. Write down the total number of bricks.

3. Add or subtract bricks to modify the design.

If you want to modify the design, add or subtract bricks from the total count determined in the previous step. Write down the new total number of bricks.

4. Multiply the number of bricks by the number of wheels.

Determine the number of wheels needed for your car design. Multiply the total number of bricks by the number of wheels to calculate the total number of wheels required.

5. Divide the total number of bricks by the number of doors.

If your car design includes doors, divide the total number of bricks by the number of doors to find out how many bricks are needed per door.

Talking Points

• "Arithmetic is a branch of mathematics that deals with numbers and their operations."
• "Addition is the process of combining two or more numbers to find their total."
• "Subtraction is the process of taking one number away from another to find the difference."
• "Multiplication is a shortcut for repeated addition. It is used to find the total when you have multiple groups of the same number."
• "Division is the process of splitting a number into equal parts or finding out how many times one number is contained within another."
• "In this activity, we will apply arithmetic concepts to determine the number of LEGO bricks, wheels, and doors needed for our car design."
