Multiplying!

Example: How many inches are in 2 feet?1. We need to go from what unit to what other

unit?2. Which is bigger, an inch or a foot?3. Since we’re going from a larger unit (feet)

to a smaller unit (inches), multiply! 4. How many inches are in 1 foot?

Dividing!

When you convert from a smaller unit to a larger unit, divide!

Example: How many yards are in 9 feet?1. We are going from what unit to what unit?2. Which is larger, a foot or a yard?3. Since we’re going from a smaller unit (feet)

to a larger unit (yard), divide!4. How many feet are in one yard?
