Objective

By the end of this lesson, you will be able to practice basic arithmetic skills using Lego bricks.

Materials and Prep

• Lego bricks (various colors and sizes)
• Number cards (0-9)
• Counting cards (1-10)
• Small container or bag to hold the cards
• Clear workspace

No prior knowledge or preparation is required for this lesson.

Activities

1. Counting with Lego:

   • Place the counting cards in a pile facedown.
   • Take a card from the top of the pile and read the number out loud.
   • Count out the corresponding number of Lego bricks and stack them neatly.
   • Repeat this process for all the counting cards.

2. Addition with Lego:

   • Choose two number cards randomly.
   • Place the corresponding number of Lego bricks for each card in separate piles.
   • Combine the two piles and count the total number of bricks.
   • Use the bricks to build a tower with the height equal to the total.
   • Repeat this process with different number cards.

3. Subtraction with Lego:

   • Choose two number cards randomly.
   • Place the corresponding number of Lego bricks for each card in separate piles.
   • Take away the bricks from one pile according to the number on the other card.
   • Count the remaining bricks and use them to build a structure.
   • Repeat this process with different number cards.

Kindergarten Grade Talking Points

• "Today, we are going to have fun with Lego bricks while practicing our math skills."
• "We will start by counting the number of Lego bricks and stacking them neatly."
• "Next, we will learn about addition. This means combining two sets of Lego bricks to find the total."
• "We will also learn about subtraction. This means taking away some Lego bricks from a pile."
• "Remember, math is like building with Lego. We can use numbers to create and solve problems!"
