Objective

By the end of this lesson, you will be able to understand basic algebraic concepts related to autumn.

Materials and Prep

• Pencil
• Paper
• Autumn-themed objects (leaves, acorns, etc.)

No prior knowledge is required for this lesson.

Activities

1. Autumn Pattern: Create a pattern using autumn-themed objects. For example, start with a leaf, then an acorn, then a leaf, and so on. Ask the student to continue the pattern. Discuss the concept of repeating patterns.

2. Missing Number: Write a sequence of numbers on the board (e.g., 1, 3, __, 7, 9). Ask the student to identify the missing number. Explain that algebra helps us find missing numbers in a sequence.

3. Number Equations: Write simple addition and subtraction equations related to autumn on the board (e.g., 2 + __ = 5, 8 - __ = 3). Ask the student to solve the equations by finding the missing number. Emphasize the use of algebra to solve equations.

First Grade Talking Points

• "Algebra is a type of math that helps us solve problems and find missing numbers."
• "In algebra, we use letters or symbols to represent unknown numbers."
• "Patterns are sequences that repeat in a specific way, just like the changing colors of leaves in autumn."
• "When we have a sequence of numbers and one is missing, we can use algebra to figure out what the missing number is."
• "We can also use algebra to solve equations, which are number sentences with missing numbers."
