Ladder Method

How do you use the “ladder” method?

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.

Counting Steps: How many steps is it from …1. kilometers to centimeters: 5 steps2. centimeters to millimeters:____________3. KL to L:________________4. m to mm______________5. millimters to centimeters:__________6. g to mg: _________________

Conversion practice: now apply step counting to these problems. Write down how many steps the conversion requires, then give the actual

answer on the 2nd lineExample: 3.5 m is how many cm?

Steps: cm to m is 2 steps (remember, “m” by itself is the base unit, (b)Answer: 350 cm
