**Grasshopper Math**

Grasshoppers are insects that can jump 10 times their height. Help Greg Grasshopper solve the problems below. Use the correct unit in your answer. Use numbers, sketches, or words to show your work.

Question 1.

Greg Grasshopper has a mass of 3 grams. He climbs onto a leaf with 9 other grasshoppers that each have a mass of 3 grams. Then 4 grasshoppers jump off of the leaf. What is the total mass of the grasshoppers that are still on the leaf?

Answer:

Total mass of the grasshoppers that are still on the leaf =15 grams.

Explanation:

Mass of Greg Grasshopper has = 3 grams.

Number of grasshoppers climbs = 9.

Number of grasshoppers jump off of the leaf = 4.

Total mass of the grasshoppers that are still on the leaf = (Mass of Greg Grasshopper has × Number of grasshoppers climbs) – (Mass of Greg Grasshopper has × Number of grasshoppers jump off of the leaf)

= (3 × 9) – (3 × 4)

= 27 – 12

= 15.

Question 2.

Greg Grasshopper lives in a rectangular garden. One side of the garden is 134 cm long. The other side is 277 cm long. If Greg Grasshopper walks all the way around his garden 2 times, how far has he walked?

Answer:

Distance he travelled so far = 822 cm.

Explanation:

Length of the One side of the garden = 134 cm.

Length of the Other side of the garden = 277 cm.

Number of times Greg Grasshopper walks all the way around his garden = 2.

Perimeter of the garden = 2 × (Length of the One side of the garden + Length of the Other side of the garden)

= 2 × (134 + 277)

= 2 × 411

= 822 cm.

Question 3.

Walking always makes Greg Grasshopper hungry. After he walked around his garden twice, he ate 387 milligrams of grass and 246 milligrams of leaves. How many milligrams did he eat?

Answer:

Total number of milligrams he ate = 633.

Explanation:

Number of milligrams of grass = 387.

Number of milligrams of leaves = 246.

Total number of milligrams he ate = Number of milligrams of grass + Number of milligrams of leaves

= 387 + 246

= 633.

Question 4.

Then Greg was tired. He fell asleep for 2 hours. When he woke up, it was 3:45. What time did he fall asleep?

Answer:

1:45 time he fall asleep.

Explanation:

Number of hours he fell asleep for = 2 hours.

Time he wokeup = 3:45.

Time he fall asleep = Time he wokeup – Number of hours he fell asleep for

= 3:45 – 2

= 1:45.

Question 5.

Greg Grasshopper has three cousins: Gary, Grant, and Garth. They all can jump 10 times farther than their length. Figure out how many jumps each cousin needs to make to travel a distance of 9 meters. (Hint: There are 100 centimeters in a meter.) Use numbers, sketches, or words to show your work.

a. Gary is 3 centimeters long.

Gary has to make ____ jumps to travel a distance of 9 meters.

Answer:

Gary has to make 300 jumps to travel a distance of 9 meters.

Explanation:

Length of Gary = 3 cm.

Number of times they all can jump = 10.

Conversion:

100 cm = 1 m.

3 cm = ?? m

=> ?? = 3 ÷ 100

=> ?? = 0.03 m.

Number of jumps each cousin needs to make to travel a distance of 9 meters.

=>9 m ÷ 0.03 m

=> 300.

b. Garth is 5 centimeters long.

Garth has to make ____ jumps to travel a distance of 9 meters.

Answer:

Garth has to make 180 jumps to travel a distance of 9 meters.

Explanation:

Length of Garth = 5 cm.

Number of times they all can jump = 10.

Conversion:

100 cm = 1 m.

5 cm = ?? m

=> ?? = 5 ÷ 100

=> ?? = 0.05 m.

Number of jumps each cousin needs to make to travel a distance of 9 meters.

=>9 m ÷ 0.05 m

=> 180.

c. **CHALLENGE** Grant is 4 centimeters long.

Grant has to make ____ jumps to travel a distance of 9 meters.

Answer:

Grant has to make 225 jumps to travel a distance of 9 meters.

Explanation:

Length of Grant = 4 cm.

Number of times they all can jump = 10.

Conversion:

100 cm = 1 m.

4 cm = ?? m

=> ?? = 4 ÷ 100

=> ?? = 0.04 m.

Number of jumps each cousin needs to make to travel a distance of 9 meters.

=>9 m ÷ 0.04 m

=> 225.
