Twice as Tall

Question 1.
How tall are you right now?

Measure from the start of the paper strip to your height line to find out.
Record the results below.

a. Number of yards ________________
b. Number of feet ________________
c. Number of inches ________________
Answer:
Height of me :
a. Number of yards = \(\frac{1}{12}\).
b. Number of feet = \(\frac{1}{4}\)
c. Number of inches = 3.

Explanation:

Height of me = ?? inches.
=> 3 inches.
Height of me = ?? yards.
Conversion:
1 yard = 36 inches.
=> ?? yard = 3 inches.
=> 1 × 3 = 36 × ??
=> 3 ÷ 36 = ??
=> 1 ÷ 12 = ??
=> \(\frac{1}{12}\) yards = ??
Height of me = ?? feet.
Conversion:
1 feet = 12 inches.
=> ?? feet = 3 inches.
=> 1 × 3 = 12 × ??
=> 3 ÷ 12 = ??
=> 1 ÷ 4 = ??
=> \(\frac{1}{4}\) feet = ??

Question 2.
Double each of the measurements above to predict how tall you would to be if you were twice your height.
a. Number of yards ________________ + ________________ = ________________
b. Number of feet ________________ + ________________ = ________________
c. Number of inches ________________ + ________________ = ________________
Answer:
Doubling of my height:
a. Number of yards = \(\frac{1}{12}\) + \(\frac{1}{12}\) = \(\frac{1}{6}\).
b. Number of feet = \(\frac{1}{4}\) + \(\frac{1}{4}\) = \(\frac{1}{2}\).
c. Number of inches = 3 + 3 = 6.

Explanation:

Doubling my height:
a. Number of yards = \(\frac{1}{12}\) + \(\frac{1}{12}\)
= (1 + 1) ÷ 12
= 2 ÷ 12
= 1 ÷ 6
= \(\frac{1}{6}\)
b. Number of feet = \(\frac{1}{4}\) + \(\frac{1}{4}\)
= (1 + 1) ÷ 4
= 2 ÷ 4
= 1 ÷ 2
= \(\frac{1}{2}\)
c. Number of inches = 3 + 3
= 6.

Question 3.
Now find out for sure how tall you would be if you were twice your height.

Double the length of your paper strip by folding it over the height line, and cutting off the extra.
Open your paper strip and measure it.
Record the results below.

a. Number of yards ________________
b. Number of feet ________________
c. Number of inches ________________
Answer:
Height of me:
a. Number of yards = \(\frac{1}{6}\).
b. Number of feet = \(\frac{1}{2}\).
c. Number of inches = 6.
=> Height of me is equal to the paper length given in the figure.

Explanation:
Paper height = 6 inches.
Height of me:
Doubling of my height:
a. Number of yards = \(\frac{1}{12}\) + \(\frac{1}{12}\) = \(\frac{1}{6}\).
b. Number of feet = \(\frac{1}{4}\) + \(\frac{1}{4}\) = \(\frac{1}{2}\).
c. Number of inches = 3 + 3 = 6.

Question 4.
Do your new measurements match your prediction?
Answer:
Yes, my new measurements match your prediction because both are same.

Explanation:
Both length of the paper is equal to the double height measurements of paper.
a. Number of yards = \(\frac{1}{6}\).
b. Number of feet = \(\frac{1}{2}\).
c. Number of inches = 6.

Piggyback Rides

In the Giant Kingdom, the bigger worms give piggyback rides to the smaller worms. Use your inchworm ruler and your paper footworm and yardworm strips to help solve the problems below.

Question 1.
How many inchworms can ride piggyback on a footworm at one time?
Answer:
12 inchworms can ride piggyback on a footworm at one time.

Explanation:
Number of inchworms can ride piggyback on a footworm at one time = ??
Conversion:
1 foot = 12 inches.
Number of inchworms can ride piggyback on a footworm at one time = 12.

Question 2.
How many footworms can ride piggyback on a yardworm at one time?
Answer:
3 footworms can ride piggyback on a yardworm at one time.

Explanation:
Number of footworms can ride piggyback on a yardworm at one time = ??
Conversion:
1 yard = 3 foot.
Number of footworms can ride piggyback on a yardworm at one time = 3.

Question 3.
One day, 27 inchworms were waiting for a ride at the pickup spot. Along came 2 footworms.
a. Can all 27 inchworms ride piggyback at the same time on 2 footworms? Fill in the bubble to show.
Yes
No
Answer:
No, all 27 inchworms cannot ride piggyback at the same time on 2 footworms because only 24 can go and 3 will be left.

Explanation:
Number of inchworms were waiting for a ride at the pickup spot = 27.
Number of footworms came along with them = 2.
Conversion:
1 foot = 12 inches.
2 foot = 12 × 2 = 24 inches.
=> Number of inchworms can ride piggyback at the same time on 2 footworms = 12 + 12 = 24.
Number of inchworms left = 27 – 24
= 3.

b. How do you know?
Answer:
It is known because 1 footwarm can only ride 12 inchworm at a time and double is 24 inchworm not 27.

Question 4.
One day, 2 footworms and 8 inchworms were waiting to cross the street. A yardworm came by and offered to give them a ride.
a. Was there enough room on a yardworm’s back for the 2 footworms and 8 inchworms to all get a ride at the same time? Fill the bubble to show.
Yes
No
Answer:
Yes, there is enough room on a yardworm’s back for the 2 footworms and 8 inchworms to all get a ride at the same time.

Explanation:
Number of inchworms were waiting to cross the street = 8.
Number of footworms were waiting to cross the street = 2.
A yardworm came by and offered to give them a ride.
Conversion:
1 yard = 3 foot.
1 foot = 12 inches.
=> Number of inchworms were waiting to cross the street =
?? foot = 8 inches
=> 1 × 8 = ?? × 12
=> 8 ÷ 12 = ??
=> (2 ÷ 3) foot = ??.
=> 0.67 foot = ??
Total number of inchworm and footworm were waiting to cross the street = 2 + 0.67 = 2.67.
=> There is enough room on a yardworm’s back for the 2 footworms and 8 inchworms to all get a ride at the same time.

b. How do you know?
Answer:
It is known because a yard can ride 3 footworm, total number of inchworm and footworm 2.67 not more than 3.

Question 5.
There are 100 inchworms waiting to get a piggyback ride to the garden.
a. If there are 1 yardworm and 2 footworms ready to give rides, how many of the inchworms can they take at the same time? Use numbers, pictures, and/or words to solve the problem. Show your work.
1 yardworm and 2 footworms can carry ________________ inchworms at the same time.
Answer:
Number of the inchworms can they take at the same time = 60.
1 yardworm and 2 footworms can carry 60 inchworms at the same time.

b. How many inchworms still need a ride to the garden? Use numbers, pictures, and/or words to solve the problem. Show your work.

______________ inchworms still need a ride to the garden.
Answer:
Number of inchworms cannot take at the same time ride = 40.
40 inchworms still need a ride to the garden.

Explanation:
Number of inchworms waiting to get a piggyback ride to the garden = 100.
Number of yardworms there ready to give rides = 1.
Number of footworms there ready to give rides = 2.
Conversion:
1 yard = 3 foot.
1 foot = 12 inches.
=> 3 foot = 12 × 3 = 36 inches.
1 yard = 36 inches.
1 foot = 12 inches.
=> 2 foot = 12 × 2 = 24 inches.
=> Number of inchworms can they take at the same time = 36 + 24 = 60 inchworm.
Number of inchworms cannot take at the same time ride = Number of inchworms waiting to get a piggyback ride to the garden – Number of inchworms can they take at the same time
= 100 – 60
= 40.

Question 6.
CHALLENGE One day, 1 yardworm and 3 footworms were all carrying full loads of inchworms on their backs. How many inchworms were there in all? Use numbers, pictures, and/or words to solve the problem. Show your work.
There were ______________ inchworms in all.
Answer:
Total number of inchworms were there in all = 72.
There were 72 inchworms in all.

Explanation:
Number of yardworms were all carrying full loads of inchworms on their backs = 1.
Number of footworms were all carrying full loads of inchworms on their backs = 3.
Conversion:
1 yard = 3 foot.
1 foot = 12 inches.
=> 3 foot = 12 × 3 = 36 inches.
1 yard = 36 inches.
1 foot = 12 inches.
=> 3 foot = 12 × 3 = 36 inches.
Total number of inchworms were there in all = 36 + 36 = 72.
