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.

4 km = _________ m

12

3

How many jumps does it take?

To convert from one unit to another is like following directions on a map.

Converting Units

Which way?Left or Right?

When going from a smaller unit to a larger unit, you move Left on the map and the decimal moves to the LEFT .

Going Left???

When going from a larger unit to a smaller unit, you move RIGHT on the map and the decimal moves to the RIGHT .

Going Right???

Practice Time

4.5 m = ? cm

What to do first in the problem

4.5 m = __ cm ?

Basic Unit Deci Centi MilliDekaHectoKilo

Start at Meters and move to the Right to Centimeters. Decimal place moves to the RIGHT two spaces.

4.5. ..

As you move the decimalyou will need to add zeros.

4 . 5 0 .

Is this your Final Answer?

4.5 m = 450 cm

Let’s do another one!

6.6 liters = _____ mL

What to do first in the problem

6.6 L = __ mL ?

Basic Unit Deci Centi MilliDekaHectoKilo

Start at Liters and move to the Right to Millileters. Decimal place moves to the RIGHT three spaces.

6.6. .. .

Check your answer!

6.6 liters = 6,600 mL

Let’s Go the Other Way!

3,580 mm = _______ m?

Let’s move to the left this time.3,580mm = ___________m?

Basic Unit Deci Centi MilliDekaHectoKilo

Start at Millimeters and move to the Left to Meters. Decimal place moves to the LEFT three spaces.

3 5 8 0. . ..

Check your answer:

3,580mm = 3.58m

Quiz Time

1. 28 cm = ? mm2. 438 cm = ? m3. 72 g = ? mg4. 202 g = ? Kg5. 2L = ? mL

How did We do??

1. 28 cm =

280 mm2. 438 cm =3. 72 g =4. 202 g =5. 2 L =

4.38 m72,000 mg0.202 kg2,000 mL

Now we will practice with the following worksheets

1.Units of length

2.Metric conversion

Try these conversions using the ladder method.

1000 mg = _______ g 1 L = _______ mL 160 cm = _______ mm

14 km = _______ m 109 g = _______ kg 250 m = _______ km

Conversion Practice

Compare using <, >, or =.

56 cm 6 m 7 g 698 mg

Compare using <, >, or =.

25) 63 cm 6 m 27) 5 g 508 mg 29) 1,500 mL 1.5 L

26) 536 cm 53.6 dm 28) 43 mg 5 g 30) 3.6 m 36 cm

Write the correct abbreviation for each metric unit.

1) Kilogram _____ 4) Milliliter _____ 7) Kilometer _____

2) Meter _____ 5) Millimeter _____ 8) Centimeter _____

3) Gram _____ 6) Liter _____ 9) Milligram _____

Try these conversions, using the ladder method.

10) 2000 mg = _______ g 15) 5 L = _______ mL 20) 16 cm = _______ mm

11) 104 km = _______ m 16) 198 g = _______ kg 21) 2500 m = _______ km

12) 480 cm = _____ m 17) 75 mL = _____ L 22) 65 g = _____ mg

13) 5.6 kg = _____ g 18) 50 cm = _____ m 23) 6.3 cm = _____ mm

14) 8 mm = _____ cm 19) 5.6 m = _____ cm 24) 120 mg = _____ g
