What do you think the first and third figures in the pattern look like?

Describe the 10th figure in the pattern.

For each table, find the constant of proportionality.

What is the relationship between these constants of proportionality?

For each table, write an equation for the proportional relationship. Let represent a length measured in meters and represent the same length measured in centimeters.

Compare the two equations you wrote for the two different tables. What do you notice?

How many cubic centimeters are there in a cubic meter?

How do you convert cubic centimeters to cubic meters?

How do you convert cubic meters to cubic centimeters?

It took Priya 5 minutes to fill a cooler with 8 gallons of water from a faucet that was flowing at a steady rate. Let  be the number of gallons of water in the cooler after  minutes. Which of the following equations represent the relationship between  and ? Select all that apply.

What does 1.6 tell you about the situation?

What does 0.625 tell you about the situation?

Priya changed the rate at which water flowed through the faucet. Write an equation that represents the relationship of  and  when it takes 3 minutes to fill the cooler with 1 gallon of water.

Was the cooler filling faster before or after Priya changed the rate of water flow? Explain how you know.

At an aquarium, a shrimp is fed gram of food each feeding and is fed 3 times each day.  How much food does a shrimp get fed in one day?

What is the constant of proportionality? What does it tell us about the situation?

If we switched the columns in the table, what would be the constant of proportionality? Explainyour reasoning.

Use  for number of days and  for amount of food in grams that a shrimp eats to write two equations that represent the relationship between  and .

If a tank has 10 shrimp in it, how much food is added to the tank each day?

If the aquarium manager has 300 grams of shrimp food for this tank of 10 shrimp, how many days will it last? Explain or show your reasoning.
