1. Metrics Luckey Beaufort Academy The only way to measure scientifically!

2. First, draw a “staircase” with 7 steps Prefixes Kilo Then, write the names of the prefixes k Hecto 1000 Then, write the symbols for the prefixes h 100 Deca Note: The “ones” is not a prefix, but holds the place for the m, l, or g da 10 “Ones” Last, write the numerical meaning of the prefix 1 Deci d Centi 0.1 meters (m) c 0.01 Milli liters (l) m grams (g) 0.001

3. Mnemonic KIDS HAVE DROPPED OVER DEAD CONVERTING METRICS All these prefixes end in “i”

4. Using the Stair-case 35.6 ml = _? _ kl Put “Yourself” on the unit you are going from How many steps AND IN WHICH DIRECTION must you go to reach the unit you’re looking for? So that’s 6 places to the LEFT, and so … 35.6 ml = 0.0000356 kl

5. Try These: • 2.17 g = _______mg • 9.90 cm = _____dam • 1.22 hl = ______L • 2.08 cg = _____kg • 4.55 kl = ______dl • 6.13 m = ______mm

6. P.S. • Those are NOT the only prefixes used in the metric system…you are familiar with… • Nano • Tera • Mega • Giga • And more! (What do these mean?) • [Look these up in your text!] • Also: HOMEWORK: finish handout
