Objective

By the end of this lesson, you will be able to understand basic algebraic concepts through a fun activity involving five black cats.

Materials and Prep

• 5 black cat cutouts
• Pen or marker
• Blank paper

No prior knowledge or preparation is required for this lesson.

Activities

1. Start by drawing five black cat cutouts on separate pieces of paper.
2. Label each cat with a different number from 1 to 5.
3. Ask the student to arrange the cats in different orders and count the total number of cats each time.
4. Encourage the student to write down the number sentences for each arrangement, such as 1 + 2 + 3 + 4 + 5 = 15.
5. Discuss with the student how the order of the cats doesn't change their total count, and introduce the concept of commutative property in addition.
6. Challenge the student to come up with different ways to arrange the cats while still maintaining the same total count.
7. Have the student create their own number sentences using the cats, and solve them together.

First Grade Talking Points

• "Today, we are going to learn about algebra, which is a special kind of math."
• "Algebra helps us solve problems using letters or symbols instead of just numbers."
• "We are going to use five black cats to help us understand algebra better."
• "We will arrange the cats in different orders and count how many cats we have each time."
• "We will write down number sentences to show the total count of the cats."
• "Even if we change the order of the cats, the total count stays the same."
• "This is called the commutative property of addition."
• "Let's challenge ourselves to find different ways to arrange the cats while keeping the same total count."
• "You can create your own number sentences using the cats, and we will solve them together."
