Exploring Proportional Tables in Math 7

The video tutorial covers the concept of proportional tables, explaining proportionality using a Pac-Man example. It demonstrates how to fill tables with proportional data, check for proportionality, and find missing values using the constant of proportionality, k. The tutorial includes examples and practice exercises to reinforce learning.

What is the main topic introduced in the first section of the video?

• Unit Rate

• Proportional Tables

• Constant of Proportionality

• Carnival Rides

In the Pac-Man problem, how far does Pac-Man travel every 6 seconds?

• 6 feet

• 12 feet

• 18 feet

• 24 feet

What is the unit rate for Pac-Man's travel?

• 6 feet per second

• 3 feet per second

• 4 feet per second

• 2 feet per second

What is another term used interchangeably with 'constant of proportionality'?

• Rate of Change

• Unit Rate

• Proportional Constant

• Speed

What must be true for a table to be considered proportional?

• It must have equal x and y values

• It must have a constant rate of change

• It must have increasing values

• It must start at (1,1)

How do you determine if a table is proportional?

• By adding all values together

• By dividing y-values by x-values and checking for consistency

• By checking if all x-values are the same

• By checking if all y-values are the same

What is the value of k if 12 divided by 3 equals 4?

• 4

• 6

• 3

• 5

If a table has the pairs (5, 90) and (6, 108), what is the constant of proportionality?

• 20

• 22

• 18

• 15

How do you find a missing value in a proportional table?

• By adding the x and y values

• By guessing

• By multiplying or dividing by the constant of proportionality

• By subtracting the x value from the y value

What is the unit rate if 90 miles are covered in 5 gallons?

• 18 miles per gallon

• 22 miles per gallon

• 15 miles per gallon

• 20 miles per gallon
