7 Essential Order Of Operations Tips For Grade 6

Understanding the order of operations is crucial for sixth graders as they delve deeper into math. It’s the set of rules that dictates the sequence in which calculations are performed to ensure everyone arrives at the same answer. This guide will help students grasp these concepts, offering helpful tips, shortcuts, and techniques to tackle problems effectively. Let’s dive into the world of order of operations! 🌟

What Is the Order of Operations?

The order of operations is a standard way to evaluate mathematical expressions. It can be remembered by the acronym PEMDAS:

• P - Parentheses: Solve expressions inside parentheses first.
• E - Exponents: Next, compute any exponents (or powers).
• MD - Multiplication and Division: Move from left to right, performing multiplication and division as they appear.
• AS - Addition and Subtraction: Finally, perform addition and subtraction from left to right.

By following this order, students can ensure they solve problems correctly every time!

Helpful Tips for Mastering Order of Operations

1. Use Mnemonics 🧠

Encourage students to remember PEMDAS by using a catchy phrase. For example, "Please Excuse My Dear Aunt Sally." This visual and auditory cue helps students recall the order easily.

2. Practice with Parentheses

Start with problems that only include parentheses and gradually introduce other operations. For example:

• (3 + 5) × 2
• 6 × (4 - 1) + 8

These problems help students understand how parentheses change the order of operations.

3. Work with Exponents Early

Ensure students practice simplifying exponents. For example:

• 2³ = 8
• 3² + 5 = 9 + 5 = 14

Integrating exponents into early practice is essential for developing fluency.

4. Emphasize Left to Right for Multiplication/Division and Addition/Subtraction

Clarify that both multiplication and division are of equal priority, as are addition and subtraction. For instance:

• In the expression 10 ÷ 2 × 3, do it left to right: (10 ÷ 2) × 3 = 5 × 3 = 15.
• Similarly, for 8 - 3 + 2, calculate as: (8 - 3) + 2 = 5 + 2 = 7.

5. Introduce Complex Problems Gradually

Once students master simple PEMDAS operations, introduce more complex problems. Here’s an example:

• (2 + 3) × (4 - 2)² + 7 = 5 × (2)² + 7 = 5 × 4 + 7 = 20 + 7 = 27

Start with simpler expressions and increase the difficulty over time.

6. Create Worksheets and Games

Interactive learning can solidify understanding. Design worksheets that combine math with fun games. Use problems that require students to solve for the answer using order of operations, allowing them to compete against each other or work in teams.

7. Troubleshoot Common Mistakes 🔍

Identifying common errors can improve understanding. Here are mistakes to watch for:

• Ignoring parentheses or incorrectly applying them.
• Not performing operations from left to right.
• Failing to calculate exponents before moving to multiplication/division or addition/subtraction.

Discuss these issues in class and help students troubleshoot them together.

Example Problem Breakdown

Let’s look at a sample problem step-by-step: Evaluate: 5 + 2 × (8 - 3)² ÷ 5

1. Parentheses: 8 - 3 = 5
   • Now we have 5 + 2 × 5² ÷ 5
2. Exponents: 5² = 25
   • Now it reads as 5 + 2 × 25 ÷ 5
3. Multiplication/Division (from left to right):
   • 2 × 25 = 50
   • Next, 50 ÷ 5 = 10
4. Addition: 5 + 10 = 15

The final answer is 15.
