1 Problem of the DaySet up the proportion needed to find the height of the tree in the picture below.
2 1-3: Measuring in Metric Units Change metric units of Length, Capacity, and Mass; Estimate metric measurements
3 Metric Measurement System VocabularyMetric Measurement SystemInternational system of weight and measurement, that utilizes the decimal system.
4 Length Capacity Millimeter (mm): Thickness of a dime. Centimeter (cm): about the width of your little finger.Meter (m): about the distance from a doorknob to the floor.Kilometer: about the length of 11 football fields; 2 ½ laps around football field track.CapacityMilliliter (mL): a spoon holds about 5 mL.Liter (L): a little more than a quart.MassMilligram (mg): About the mass of a mosquito.Gram (g): About the mass of a paper clip.Kilogram: About the mass of a pair of shoes, baseball bat.
5 Estimating metric measures… Length of a pencil.Height of the classroom ceiling.Mass of a textbookLength of the SmartboardMass of a student deskThickness of a piece of paperThickness of a textbook8) Capacity of a typical water bottle9) Length of the classroom10) Length of your desktopAbout 19 cmA little more than 3 mAbout 1 kg1 ½ metersAbout 5 kg1/3 of a mm3 ½ cm½ a liter7 metersAbout 30 cm

7 Keep in mind... Cross cancellation simplifying when multiplying fractions. 5 x 18 =6 25Canceling also holds true for units…871 cm x 1 m =cm
8 To convert units within the metric measurement system… THINK: Are you going to a “larger” unit or a “smaller” unit. Will you have more or less of the new unit???Determine the base unit conversionsSet-up the conversion factor that will cancel the original unit, while introducing the new unit.Multiply factors, canceling units where necessary
9 Problems/Examples of A) ___ L = 90 mL 1 L = 1000 mL 90 mL x 1 L
10 Problems/Examples of B) 0.6 mL = ___ L 1 L = 1000 mL 0.6 mL = 1 L
11 Problems/Examples of C) ___ mg = 2.7 kg 1 kg = 1000 g 2.7 kg x 1000 g 1 g = 1000 mg2700 g x 1000 mgg
