10. PRE ASSESSMENT: What form of measurement system are you more used to? • Metric (meters, liters, grams) • English (feet, pounds, inches, etc) • I am equally used to both of these systems • I am used to a different system

11. PRE ASSESSMENT: Imagine you know the Metric and English systems equally well. Which do you think is a better system to use? • Metric (meters, liters, grams) • English (feet, pounds, inches, etc) • Not sure – I need to learn more before deciding

12. PRE ASSESSMENT: Do you think the entire world should be obligated to use one, universal, worldwidesystem of measurement (EITHER metric, OR English, etc)? • Yes • No • Not quite sure – need to learn more before making a decision

13. As a class, we will read the articles… • Expect to stop during the articles for comments, questions, and feedback. • Feel free to highlight, take notes, etc. • SHARE what works best for you when you are reading a text for understanding • These are yours to keep – they are NOT graded! • You may bullet point for the questions (do not have to use full sentences)

14. Debate (pending time) • 2 groups – pro/con for the worldwide use of the metric system • _____ minutes to discuss as a group and use smart phones for additional research • Each individual has the opportunity to state 1 reason for their decision, followed by evidence based reasoning. • Once an individual from one group has spoken, an individual from the other side will have a chance to rebut (once again, using evidence!) • You cannot speak again until at least ____ people on YOUR SIDE have spoken • You may change sides at ANY TIME by walking to the other group.

15. POST ASSESSMENT: Imagine you know the Metric and English systems equally well. Which do you think is a better system to use? • Metric (meters, liters, grams) • English (feet, pounds, inches, etc) • Still not sure!

16. POST ASSESSMENT: Do you think the entire world should be obligated to use one, universal, worldwidesystem of measurement (EITHER metric, OR feet/pounds, etc)? • Yes • No • Still not sure!
