How do you use the “ladder” method?
4 km = _________ m
1st – Determine your starting point.
2nd – Count the “jumps” to your ending point.
3rd – Move the decimal the same number of jumps in the same direction.

5. Practice Time Compare using <, >, or =
1000 mg = _______ g 1 L = _______ mL 160 cm = _______ mm
14 km = _______ m 109 g = _______ kg m = _______ km
1000 mg = 1 g 1 L = 1000 mL cm = 1600 mm
14 km = m 109 g = kg m = 0.25 km
Compare using <, >, or =
56 cm m 7 g mg
56 cm < 6 m g > mg
