Understanding the Order of Operations and the Distributive Property in Problem Solving

This lesson focuses on using the order of operations to solve mathematical problems effectively. Students will practice applying the distributive property to multiply simple polynomial expressions. Engaging activities include writing a paragraph about the order of operations and engaging in critical thinking exercises. By examining a practical example involving a former president's purchase, students will learn to analyze and solve real-world math problems without calculators. Additional number tricks offer a fun way to interact with math concepts.

  1. Unit 1 Lesson 3

  2. Let’s Review • BAG

  3. Recall;

  4. Pull out a clean sheet of paper • Write a paragraph, 5 to 6 sentences, about how to use the order of operations when solving this problem;

  5. “I Can…” • “…apply the distributive property and multiply simple polynomial expressions.” • M(F&A)10-3

  6. Iced Coffee, a bagel, and a donut • If 5 of each every week… • If every week of the year…

  7. In all its glory…the DISTRIBUTIVE PROPERTY

  8. EXAMPLES

  9. What about this??? • NO CALCULATORS!

  10. Critical Thinking… • Former President Bush bought Dunkin Donuts for his security team. He paid $213 for everything. If coffee was twice as much as donuts, how much money was spent on coffee? Donuts?

  11. Number Tricks • Think of a number between 1 and 25 • Add 9 to your number • Multiply the result by 3 • Subtract 6 from the current answer • Divide the answer by 3 • Now subtract your original number Textbook page 135-141 #’s 4-6
