1. Converting
Between
Units of
Length

2. Directions
Please
read the slides and
answer any questions along the
way before going on to the
next slide.

3. Goal: I can convert between
standard units of length.

4. Think: What do you know
about converting between
units of length?
Hint: Units of measurement include inches, feet, yards, and miles.

5. Units of Length
 12
inches = 1 foot
 3 feet = 1 yard
 1,760 yards in a mile

6. Conversion Problems
 How
many inches are in 2 feet?
 How
many yards are in 9 feet?
 How
many inches are in 2 yards?

How many inches are in 2 feet?
2 feet = 2 x 12
= 24 inches
How many yards are in 9 feet?
9 feet = 9 ÷ 3
= 3 yards
How many inches are in 2 yards?
1) 2 yards = 2 × 3
= 6 feet
2) 6 feet = 12 × 6
= 72 feet

Word Problem
 Mrs.
Sunflower’s class grew a spinach
plant, a basil plant, and a tomato plant.
The spinach plant was 5 feet tall. The basil
plant was 36 inches tall. The tomato plant
was 2 yards tall. List the plants’ heights
from shortest to tallest. Please explain all
thinking.

Answer: As you can see in my table the tomato is the
tallest plant. I know this because 72 inches is greater than
the 60 inches of the spinach plant and the 36 inches of
the basil plant. I found my answer by converting
between units and then comparing the number of inches
for each plant.
