  1. Unit 08: Two Dimensional Measurement Ms.Clark’s 6th Grade Math TEKs:6.8B Select and use appropriate units, tools, or formulas to measure and solve problems involving length (including perimeter), area, time, temperature, volume and weight.

  2. Do Now • 1. Find your folder/Get a folder and put your name on it. • 2. Grab a length of paper from the work station. • 3. Answer question: How would you measure the strip of paper? Why? Using a piece of paper.

  3. Objective/Agenda Objective: Today you will be able to identify the difference between metric and customary forms of measurement. Agenda: Warm-Up What is measurement Difference between Customary and Metric

  4. What Do the Simpson’s Have to Say About Measurement? Metric System? Have you heard about it? Hint: You use it in Ms. Davis’ class.

  5. Class Discussion • Why do you think a foot is called a foot? • Where did the word inch come from?

  6. History of Measurement • Measurement has always depended on what humans have on hand.

  7. You Try! • With your partner you will go to the work station and sign out one bag for your team. • You must return your bag at the end of the period and sign it in. • Make sure to grab both papers Measuring with the Human Body and Converting with the Human Body. • Sit in your seat and quietly wait for instructions.

  8. Do Now Yesterday we talked about different types of measurement. Talk to your partner about how you would measure the elephant: Finished: Sign out your materials for your team.

  9. What are we doing today? Objective: Students will define units of metric and customary systems. Language Objective: Students will sort what vocabulary goes in what unit. Agenda: Explore Units of Measurement Vocabulary Building

  10. Practice Converting • You will move around and talk to one person in the room that has the same length pinkie as you. • Using your sheet from yesterday, tell them why you picked 3 of the items you choose to measure. • You will need to remember one of theirs to share with the class.

  11. Check in What customary unit would you use to measure the elephant? Write on the back of your work sheet. • Inch • Mile • Foot

  12. STAAR Reference Guide Foldable 1 Mile (mi) = 1,760 yards 1 yard(yd) = 3feet (ft) foot (ft) = 12 inches (in) We call this our customary unit. It is the tradition of the U.S • Which one is bigger? Why? • Which one is smaller? Why?

  13. How to we Convert Between Units Ms. Clark’s nephew Jordan is about 6’0 ft tall and in the 8th grade. If I want to find out how tall my nephew is in inches I would have to figure out these steps. 1. Look at staar chart 12 in = 1 ft 6 X 12 = 72 inches (this is why multiplication is important) My nephew is 72 in tall.

  14. We Try • A Cheetah can run 61 miles in 1 hour (mph), How fast can the cheetah run in yards? Hint: 1 mile is equal to 1,760 ft

  15. Let’s Get Moving Around the room there are 5 different measurements I need you to convert. Step 1: Label a piece of paper 1 to 5. Step 2: Make sure the paper says your name on it. Label

  16. Exit ticket Ms. Clark is 5 feet and 3 inches tall. How tall is she in inches? Show your work If you need help come ask Ms. Clark on her first day of college

  17. Do Now • Ms. Weaver wants to make a line of Takis the length of a football field. If the football field is 120 yards, how long is it in feet? • Show your work!

  18. Announcements • Having trouble remembering your homework? • I can help you! Please take out your cell phones or a piece of paper.

  19. Objective • Today you will learn how to convert between metric unit lengths using your STAAR reference guide. • Language objective: Students will understand the prefixes of the metric system. Agenda • Do Now • What is the metric system and making our length foldable • Measuring using the metric system.

  20. How To Make A Foldable You will be making a foldable today. 1. You will fold your paper length wise 2. Open it up 3.Fold both edges to your middle line. 4. Cut four flap on each side

  21. The History of the Metric System

  22. Check-In Class discussion: How is the metric system different than the U.S customary system we learned about the last two days? 2. If you had to pick, which unit of measurement would you have voted for? Why?

  23. Metric Unit of lengths Millimeter: Mil or 1000 times smaller than a meter. Centimeter: Centi (Cien) 100 times smaller than a meter. Meter: Base unit of measurement a little bigger than three feet. Kilometer: 1000 meters or about 3,000 ft. Less than a mile.

  24. Converting Between The metric System • When watching the video attached please make sure to copy the staircase shown.

  25. Comparing units of Length • U.S customary based off of body parts Inch Mile Foot Yard Metric System Based off the length of earth around. Millimeter Centimeter Meter Kilometer

  26. Measuring Outdoors You will need a meter stick and a ruler. You will be measuring something that is a Meter Centimeter Millimeter Choose your actions, you do not choose your consequence.

  27. Do Now: January 31st 2013 Gio jogs 3,189.4 meters, and Cheyenne jogs 2,352.8 meters. How much farther does Gio jog than Cheyenne? • 836.4 meters • 727.6 meters • 837.4 meters

  28. What are we learning today? Objective: Today you will learn how to measure the area of a rectangle. Language: You will understand the difference between width and length and how to say a mathematical equation. Important words: Area Equation

  29. Announcements Sign up for Remind101 Text (240)380-2078 Message @msclarka Quiz tomorrow on Metric/Customary Units. • 3 questions + 1 bonus • Converting in Customary Units • Converting in Metric Units • Word problem on Multiplication

  30. Review of Metric System If a Sea Slug is 8cm how many millimeters long is it? Show your work!

  31. What is Area? Area: how much space an object takes up in two-dimensions. Example: If George puts his piece of paper on his desk, the paper takes up so much of it.

  32. Check For Understanding • How would you describe area to someone who hasn’t heard it? • Share with the person next to you

  33. Rectangle • A rectangle has four sides: In Math we call this a quadrilateral. • We can tell how much space a rectangle takes up by multiplying.

  34. Area Formula • The formula for a Rectangle is Length x Width (Height). • You’ll see it on your test as A= B x H

  35. Rectangle Game • Goal: To have the most amount of rectangles at the end of the game. • Tools: 2 color pencils 2 regular pencils Calculator Graph Paper (1 per 2 people) 2 Rulers 2 Random Number Generators

  36. Rectangle Game Instructions • Pick who goes first • Roll the RNGs • Pick one number to be your length and one number to be your width. • Draw your rectangle • Multiply to find area • Switch partner Goal: To have the most triangles at the end.

  37. Exit Ticket • Samantha wants to know the area of the folder that is on her desk. If her folder is 8.5 by 11 inches, What is the area of the folder? • Area=Base x Height
