Answer:

100 L – 95 L= 5 L

5 Liters of water will be left in the 100 L container.

**Turn and Talk** How did you decide what equation to write to solve the problem?

Answer:

If we need total we need to use addition equation, if we need the leftover we need to use subtraction equation.

Question 2.

Pete ships a care package to his brother at camp. The mass of the soap bar is 58 fewer grams than the mass of a tube of toothpaste. What is the mass of the tube of toothpaste?

A. What information is unknown?

Answer:

The mass of toothpaste is unknown.

B. Use the information in the problem to complete the bar model.

Answer:

C. Use the bar model to write an equation to solve the problem.

Answer:

The mass of soap is 79 grams, the mass of soap is 58 grams fewer than mass of toothpaste

Mass of toothpaste = 79 + 58 = 137

D. What is the mass of the tube of toothpaste?

Answer:

137 grams

Answer:

C. Write a multiplication equation to represent the problem.

Answer:

The multiplication equation that shows the mass of 6 markers is 9g x 6 = 54g.

D. What is the mass of 6 markers?

Answer:

The mass of 6 markers is 54grams.

**Turn and Talk** Describe the visual model and the equation you used to solve the problem.

Answer:

I drew 6 rows of 9 counters each to show 6 markers with 9 grams mass

The equation is 9 x 6 = 54 g.

Question 3.

**Model with Mathematics** Jamal’s car has a full tank of gas. Then he uses 24 liters of gas. There are 16 liters of gas left in the tank. How many liters of gas are in a full tank?

Write an equation to solve the problem.

Answer:

40 liters

Explanation:

Jamal’s car has a full tank of gas.

Then he uses 24 liters of gas.

There are 16 liters of gas left in the tank

24+ 16 = 40

40 liters of gas are in a full tank.

How many liters of gas are in a full tank?

Answer:

40 liters of gas are in a full tank.

Question 4.

**STEM** An ice cube has a mass of 28 grams. After it is left out on a warm counter, it has a mass of 13 grams. How many fewer grams of mass does the ice cube have after being left on the counter? Write an equation to solve the problem.

Answer:

15grams

Explanation:

An ice cube has a mass of 28 grams.

After it is left out on a warm counter, it has a mass of 13 grams

28 – 13 = 15

15 fewer grams of mass the ice cube have after being left on the counter.

Question 5.

**Model with Mathematics** Each ball of yarn has the mass shown Esther buys several balls of yarn that have a mass of 56 grams. How many balls of yarn does she buy?
