Objective

By the end of this lesson, you will be able to confidently evaluate mathematical expressions using different operations.

Materials and Prep

• Paper
• Pencil
• Calculator (optional)
• Basic understanding of addition, subtraction, multiplication, and division

Activities

• Expression Scavenger Hunt: Create a list of expressions for the student to solve around the house. For example, "2 + 3 x 4 - 5".
• Math Bingo: Create a bingo card with various expressions. Call out the results, and the student has to mark the correct answer on their card.
• Expression Art: Use different colored markers to represent different operations in an expression. For example, red for addition, blue for subtraction, etc.

Talking Points

• Addition and Subtraction: "When you see a plus or minus sign in an expression, you need to perform the operation in order from left to right."
• Multiplication and Division: "Multiplication and division have higher priority than addition and subtraction. Remember to solve them first."
• Using Parentheses: "Parentheses can be used to indicate which operations should be done first. Always solve what's inside the parentheses first."
• Practice Makes Perfect: "The more you practice evaluating expressions, the more confident you will become in handling complex math problems."
