Objective

By the end of this lesson, you will be able to apply arithmetic skills to solve problems using Legos.

Materials and Prep

• Lego bricks (various sizes and colors)
• Pen and paper
• Counting objects (optional)

No prior knowledge is required for this lesson.

Activities

1. Counting and Sorting:

   Start by counting the number of Lego bricks you have. Sort them by color or size into different groups.

2. Addition and Subtraction:

   Create simple addition and subtraction problems using Lego bricks. For example, if you have 5 red bricks and 3 blue bricks, how many bricks do you have in total? If you take away 2 red bricks, how many will be left?

3. Pattern Building:

   Use Lego bricks to create different patterns. For example, you can make a pattern of red, blue, red, blue, or a pattern of small, medium, large, small, medium, large.

4. Measurement:

   Use Lego bricks to measure objects around the house. How many Lego bricks long is the table? How many bricks tall is a book?
