Objective

By the end of this lesson, the student will be able to apply arithmetic concepts to build a Lego robot.

Materials and Prep

• Lego building blocks
• Pen and paper
• Calculator (optional)
• No prior knowledge required

Activities

• Activity 1: Counting Blocks

  Have the student count the number of Lego blocks they have available for building their robot. Encourage them to write down the count on a piece of paper.

• Activity 2: Addition Challenge

  Ask the student to add different numbers of Lego blocks together to find the total. For example, "If you have 3 red blocks and 5 blue blocks, how many blocks do you have in total?"

• Activity 3: Subtraction Challenge

  Challenge the student to subtract blocks from their total. For example, "If you have 10 blocks and you remove 4 blocks, how many blocks are left?"

• Activity 4: Multiplication Challenge

  Encourage the student to use multiplication to determine the number of blocks needed for specific robot parts. For example, "If each leg of the robot requires 2 blocks, how many blocks do you need for all 4 legs?"

Talking Points

• "Mathematics is important in many real-life situations, including building a Lego robot."

• "Counting is the foundation of arithmetic. It helps us keep track of how many objects we have."

• "Addition is combining two or more numbers to find the total."

• "Subtraction is taking away a number from another number to find what is left."

• "Multiplication is a way to quickly add groups of the same number."

• "By using arithmetic, we can plan and calculate the number of blocks needed for different parts of the Lego robot."
