2. Drill # 139/11/2014  Write drill # 13 and the date in your notebook  Copy the questions (they are on the right side of the board)  Answer  7 minutes, everyone is quiet and in her/his seat

3. Topic: Factor-Label Method Practice Objective: Students will be able to  Apply the factor-label method to change units of measurement HW #10: Get worksheet

4. Equivalence statements English-MetricMetric-Metric  1 inch = 2.5 cm  1 lb = 0.45 kg  1 mile = 1600 m  1 m = 100 cm  1 m = 1000 mm  1 m = 1000 000 μm  1 cm = 10 mm  1 km = 1000 m  1 L = 1000 mL  1 kg = 1000 g

5. Factor-labels  Make a fraction from the equivalence statement  One side goes on top of the other  There are two factor-labels for each equivalence statement  Both equal 1 (one as the number)  Example: 1 inch or 2.5 cm 2.5 cm 1 inch

6. Change the unit  Multiply the quantity you know by one of the factor-labels  Which one?  The one that will help you cancel the unit you are trying to get rid of  example  30 inches to cm  30inch x 2.5cm / 1inch  30 x 2.5 /1 cm = 75 cm

7. Guided Practice – 5 problems 20 minutes, timed  Work with your group  Use inside voices  Be nice  Ask your teammates for help  Use a calculator  Solve the problem on the right screen together  Everyone writes on her/his own paper  Team recorder writes the complete solution on your white board  Hold up your board when time is called  Make corrections if needed  Make sure that everyone in the group understands how to do the problems

8. Individual Practice-Work quietly for 20 minutes on your own  Read “Time and Length” section (3-page packet  Do not write on the handout (I have to use it again today)  Take Cornell notes on your own paper  Read one paragraph at a time  Write the main idea  Include 1-2 details  Move to the next paragraph

9. Factor- label Is same as conversion factor
