1. Countdown Warm Up

2. Ten Minute Math LARGEST DECIMAL You will have 30 seconds to decide which decimal you think is the largest. 0.464.06

3. Ten Minute Math LARGEST DECIMAL You will have 30 seconds to decide which decimal you think is the largest. 3.143.41

4. Ten Minute Math DECIMALS Find the EXACT answers. Discuss the results. *Remember to line up your decimals! 17.75 – 1.25 = 6.07 + 2.3 = 16.50 8.37

5. Mark your spot, Look to the right 4 or less are out of sight 5 or more will buy 1 more Before they too go out the door In those empty right-hand spaces 0’s take their proper places. Review Round Rap REPEAT Altogether

6. Ten Minute Math DECIMALS Round to the nearest TENTH and solve. Discuss the results. *Remember to line up your decimals! 5.73 – 2.39 = 8.93 + 3.27 = 5.7 – 2.4= 3.3 9.0 + 3.3= 12.3

7. TARGET THE QUESTION Mrs. Morris bought a kit to make a square pillow. The page listing the contents of the kit is shown below, including the tear in the chart. BALLOON PILLOW KIT Materials included: 1 yard of yellow fabric 48 inches of lace Needle Embroidery floss (colors and Amount of each color are shown in chart) Color Amount of floss Pink 12 yards Red 15 yards Blue 2 feet Green feet feet Yellow 8 yards 2. How much more red floss than blue floss is provided in the package? After discussing answer, Click for Solution: 15 yds (red) - 2 ft (blue)= 15 x 3= 45 45 ft (red) – 2 ft (blue) = 43 ft

8. Metric Measurement LENGTH

9. These are the Length Metric Units of Measurement. 1,000 millimeters (mm) = 1 meter (m) 100 centimeters (cm) = 1 meter 10 decimeters (dm) = 1 meter 1 kilometer (km) = 1,000 meters

10. Millimeters Millimeter about as wide as a dime.

11. Centimeters Centimeter about as wide as your pinkie.

12. Meters Take a big, giant step. That step was about a meter long. One meter is a little bit more than 3 feet.

13. Kilometers 1 kilometer = 2 1/2 times around a track or 0.6 miles

14. Reading Measurement Tools Distribute a ruler and yardstick/meterstick to each student. Review with them how to read measurement tools. Can you find a millimeter? A centimeter? A foot? How many feet are in each yard? So how many inches in each yard? Can you use your meterstick to show how many millimeters in a centimeter? How many centimeters are in a meter?

15. Reading Measurement Tools Work with a shoulder partner to answer the following questions in your math notebooks: (Give students about 10 mins.) 1.Which is larger, an inch or a centimeter? 2.Which is larger, a meter or yard? 3.How many inches are between 7 and 11 on the ruler? 4.How many millimeters are in one centimeter? 5.How many millimeters are between 47 and 51 on the meterstick? 6.What does the 90 on the meterstick mean? 7.How many centimeters are in one meter? After 10 mins, have students share their answers and explain their reasoning.

16. Using Measurement Tools Foot, Meter, Centimeter, Inch, Yard We use two systems of measurement in the United States. Sometimes we use the U.S. Standard System and other times we use the Metric System. Do you know which of these units are metric units? Centimeter and Meter So which units are part of the U.S. Standard System? Inch, Foot, and Yard * It is important to NEVER mix these units. For example, it is common to identify a measurement as 5 feet 2 inches but NOT as 1 foot 3 centimeters.

17. Using Measurement Tools Pass back out Student Activity p. 2 from Monday. Students will now measure the lengths of what they estimated during Monday’s lesson. They will record their measurements in the final column. When students complete all their measurements, have them compare with their shoulder partner and record their measurements under their own.

18. Discussion: Estimate of Exact? Discuss with your should partner which measurements from your sheet you would want to know the exact length and which ones you might just need an estimate. (2 mins) Allow students to share their thoughts and reasoning with the class from their discussion with their shoulder partner.

19. Discussion: Why are our measurements different? Were all of your exact measurements the same as your partners? If not, why do you think all of our measurements are not the same as each others? What are some thing we want to remember about measuring? Copy the next slide into your math notebooks titled “Guidelines for Measuring”

20. Guidelines for Measuring Don’t Mix metric and standard units. Hold the ruler straight against the thing you are measuring. Mark where the ruler ends with your finger, and then move the ruler and start it at your finger. You could use a pencil instead of your finger. Make sure you start measuring at 0. Write down each time you put the ruler down so you don’t lose track.
