The “Ladder” KHDUDCM

5
KILO 1000 Units HECTO 100 Units DEKA 10 Units DECI 0.1 Unit CENTI 0.01 Unit MILLI 0.001 Unit Meters Liters Grams

6
Ladder Method The Ladder 1st – Determine starting point. 2nd – Count “jumps” to your ending point. 3rd – Move the decimal the same number of “jumps” and in the same direction.

7
4 km = _________ m How many jumps does it take? Starting Point Ending Point 4._. 123 = 4000 m

8
Try these conversions using the ladder method. (1)1000 mg = _______ g (2) 1 L = _______ mL (3)160 cm = _______ mm (4) 14 km = _______ m Conversion Practice

9
Try these problems using the ladder method. (1)1000 cg >,,<,= 130 hL Conversion Practice
