Mass, Volume & Length Review
Question 1.
Anabel’s turtle has a mass of 413 grams. Her frog has a mass of 288 grams. Does the mass of both pets put together equal a kilogram? If not, how much less than a kilogram is the mass of both pets added together? Show your work using numbers, sketches, or words.
Answer:
Mass of Anabel’s turtle = 413 grams
Mass of Anabel’s frog = 288 grams
When both the masses are put together = 413 + 288
= 698
Generally , 1 kilogram = 1000 grams
Then 1000 – 698
= 302 grams
Therefore the mass of both pets is less than 1 kilogram.
Question 2.
Raphael had a bottle of water with 1,000 milliliters of water in it. He drank 376 milliliters of water. Then, he went for a run. After his run, Raphael drank 574 more milliliters of water.
a. How much water did Raphael drink in all? Show your work using numbers, sketches, or words. Be sure to label the answer with the correct unit.
Answer:
The total volume of water in the bottle = 1000 milliliters
Initially, the volume of milliliters he drank = 376 milliliters
Number of milliliters he drank after running = 574
The total volume of water he drank =?
= 376 + 574
= 950 milliliters.
b. How much water was left in Raphael’s water bottle? Show your work using numbers, sketches, or words. Be sure to label the answer with the correct unit.
Answer:
The total volume of water in the bottle = 1000 milliliters
Amount of water left in the bottle =?
= Total liters – volume he drank
= 1000 – 950
= 50 milliliters.

Measurement & Fractions
Question 1.
A marble has 5 times the mass of a paperclip. Peter puts 3 marbles on one side of a pan balance scale.
How many paperclips should Peter put on the other side to balance with the marbles? Show your work.
Peter should put ____ paperclips on the other side of the balance.
Answer:
Number of times that the mass of a paperclip present = 5
Number of marbles kept on one side of a pan balance scale = 3
Number of paperclips must be kept on the other side in order to balance = ?
= 5 x 3
= 15
Question 2.
Tanner’s dog dish has 4 times as much water as Lily’s cat bowl. Lily’s cat bowl has 200 milliliters of water in it.
How much water is in Tanner’s dog dish? Show your work and label your answer with the correct units.
Tanner’s dog dish has ______________ ______________ of water.
Answer:
Volume of water present in Lily’s cat bowl = 200 milliliters
