7. Warm Up Objective: SWBAT solve real-world and mathematical problems using ratio and rate reasoning to review for unit assessment. Language Objective: SWBAT apply ratio language in real-world problems. Try these thinking questions for our warm-up. • Pick two odd numbers between 0 and 100. • Write these numbers as a simplified ratio. • Pick two even numbers between 0 and 100. Write these numbers as a simplified ratio. • What do you notice that is different between the ratio of #1 and #2? Agenda

11. Explore – Jeopardy (Whole Class) Let’s play Jeopardy! Before we begin, let’s get into small groups and review the rules! • Suggested Jeopardy Rules: • 2-3 students per group • All students must show their work on Jeopardy sheet • We only count points for correct answers • We do NOT take away points for wrong answers (except in Final Jeopardy) • 1 answer per group for each question • 90 seconds time limit for each question Agenda

13. Launch - Final Jeopardy (Whole Class) If Oscar runs 9 miles in 72 minutes. How many miles will he run in 2 hours? Make sure to label your answer! ANSWER: 15 miles 72 minutes/9 miles = 8 minutes per mile 2 hours = 120 minutes 120 minutes/8 minutes per mile = 15 miles Agenda

14. Summary (Independent) • Michelle is not in class today! • Write her a letter that : • Tells her how to write a ratio in 3 ways • Reminds her the definition of rate • Reviews 2 key concepts that we covered in Jeopardy • A suggestion on how to study for our test Dear Michelle, Today in class, _________________________________ _______________________________________________.

17. Assessment (Independent) Ms. Dean is the adviser of Eastern High School’s student council. At their last meeting, 20 students ate 5 pizzas. 1) Write a ratio in simplest terms of students to pizzas in 3 ways. 4 students to 1 pizza 4 students : 1 pizza 4 students 1 pizza 2) Write a sentence explaining your ratio in #1. For every 4 students at the meeting, 1 pizza will be eaten. 3) Based on last meeting’s student to pizza ratio, how many pizzas should Ms. Dean order for the next meeting, if there will be 30 students in attendance? Ms. Dean will need to order 8 pizzas to feed 30 students. There will be ½ a pizza leftover. Agenda

18. 21st Century Lessons The goal… • The goal of 21st Century Lessons is simple: We want to assist teachers, particularly in urban and turnaround schools, by bringing together teams of exemplary educators to develop units of high-quality, model lessons.
