Objective

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

Materials and Prep

• Legos (various sizes and colors)
• Number flashcards (0-10)
• Counting chart (0-20)
• Pencil and paper

Before starting the lesson, make sure you are familiar with basic addition and subtraction concepts.

Activities

1. Counting with Legos:

   Use the counting chart and Legos to practice counting from 0 to 20. Place the corresponding number of Legos on each number on the chart.

2. Building Addition Towers:

   Choose two number flashcards and build two towers with the corresponding number of Legos. Then, combine the towers and count the total number of Legos.

3. Subtraction Challenge:

   Build a tower with a certain number of Legos. Remove some Legos and ask your student to count how many are left. Repeat with different numbers.

First Grade Talking Points

• "Math is all around us, even in our favorite toys like Legos!"
• "Counting is important because it helps us keep track of how many things we have."
• "When we add Legos together, we are finding the total number of Legos."
• "Subtraction is when we take away some Legos from a group and see how many are left."
• "Let's use Legos to practice our addition and subtraction skills!"
