  7. A Word About PowerPoint These Presentation Files were designed to be used on a PC version of MS PowerPoint. Many of the features will work on PowerPoint for Mac 2011 but some are not compatible with older versions . Please test your file before using in class!

  8. Warm Up OBJECTIVE: SWBAT solve ratio problems by using tape diagrams and ratio tables. Language Objective: SWBAT describe how to solve a ratio problem to other students in a small group. Describe something on the American flag that has each given ratio. White stripes to red stripes 1. 6 to 7 2. 7 to 13 3. 6 to 13 4. 3 to 25 White stripes to all stripes White stripes to stars Red stripes to all stripes Agenda

  9. Agenda: OBJECTIVE: SWBAT solve ratio problems by using tape diagrams and ratio tables. Language Objective: SWBAT describe how to solve a ratio problem to other students in a small group. 1) Warm Up - independent 2) Launch – Think, Pair, Share – partners 3) Explore: Problem Set Practice - independent Expert Groups – small group Jigsaw Share – small groups 4) Summary - independent 5) Exit Ticket - independent

  10. Launch – Think, Pair, Share You have learned about two great tools for solving ratio problems. Can you name the tools? T A P E D I A G R A M S R A T I O T A B L E S Lefty – Tell Righty what a tape diagram is. Righty – Tell Lefty what a ratio table is. Today you are going to practice using both tools. Agenda

  11. Explore – Independent Practice You will now practice solving some ratio problems. Your teacher will assign you 1 problem set to focus on. If you finish quickly do any of the other problem sets. You will need to do all the problem sets before the end of class. You have 15 minutes. Agenda

  12. Explore – Expert Groups • You will be split into 6 small groups. Everyone in your group just did the same problem set you did. • You will become an experton that problem! • Each member of the expert group will create an expertdescription of how to solve the problem. • Use either a tape diagram, a ratio table, or a shortcut for those tools to solve the problem. Show your work! • Make sure you can describe how to solve the problem to another person. You may want to practice! Agenda

  13. Explore – Expert Groups Work together with your expert group to solve the problem using a tool. Show your work. Write a description of what to do. You will have only 10 minutes. Agenda

  14. Explore – Problem Review: Jigsaw • We are going to do a “Jigsaw” sharing of the problems. • I will mix up the groups. Each new group will include at least one expert on each of the problem sets. • Sometimes there will be more than one expert for a problem in the same group. Agenda

  15. Explore – Problem Review: Jigsaw • In your new groups, read each problem together and brainstorm how to solve it. Take a minute or so to think for each problem. • Experts, now it’s your turn to tell the group how you solved the problem. Everyone needs to write a solution on their own papers. Umm, excuse me, I’m an expert on the problem. Shouldn’t I just tell the group what to do? Oh, ok. Give them a chance to think about it first. Sure! • You are responsible for having a complete and correct worksheet at the end, so listen carefully! Experts, please wait until your group has brainstormed first before you tell them what you know! Agenda

  16. Explore – Jigsaw Share Jigsaw Share You may begin sharing. Each person will have 3 minutes. Optional: Video Review of Problem A https://vimeo.com/47678975 Agenda

  17. Explore – Review and Complete Practice Problems Wrap it up! Make sure you have solutions for every problem. All work should be complete. Turn in your work! Agenda

  18. Summary Write your responses in your notebook. What is one thing you liked about the lesson today? What is one thing that was difficult today? Is there anything that is still confusing about solving ratio problems (so far)? Agenda

  19. Exit Ticket Use any tool you wish to solve this problem. Show all your work. Write your responses in your notebook. The ratio of Grade 6 students to Grade 7 students on a field trip is 7:5. In all, 84 students went on the trip. How many 6th grade students went on the field trip? Agenda

  20. 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. These lessons are intended to: • Support an increase in student achievement; • Engage teachers and students; • Align to the National Common Core Standards and the Massachusetts curriculum frameworks; • Embed best teaching practices, such as differentiated instruction; • Incorporate high-quality multi-media and design (e.g., PowerPoint); • Be delivered by exemplary teachers for videotaping to be used for professional • development and other teacher training activities; • Be available, along with videos and supporting materials, to teachers free of charge via the Internet. • Serve as the basis of high-quality, teacher-led professional development, including mentoring between experienced and novice teachers.
