Combinations of Coins and Graphs

This video tutorial is a cooldown exercise for Unit 4, Lesson 10, focusing on analyzing a coordinate plane that represents combinations of dimes and quarters. The lesson guides students through identifying combinations of 12 coins and combinations that total three dollars. It also challenges students to find the unique combination that satisfies both conditions simultaneously, using the graph as a visual aid.

What does the coordinate plane in the lesson represent?

• Combinations of pennies and nickels

• Combinations of dimes and quarters

• Combinations of nickels and dimes

• Combinations of quarters and nickels

Which line on the graph shows combinations of dimes and quarters that are worth three dollars?

• The line labeled with three dollars

• The line labeled with 12 coins

• The line that intersects the y-axis

• The line that intersects the x-axis

What does the line representing 12 coins indicate?

• The total value of coins is 12 dollars

• There are 12 quarters

• The total number of coins is 12

• There are 12 dimes

What does the x-axis represent in the graph?

• Total number of coins

• Number of quarters

• Number of dimes

• Total value in dollars

How can you find a combination of 12 coins on the graph?

• By looking at the intersection of the lines

• By finding a point on the line labeled with 12 coins

• By counting the number of dimes

• By counting the number of quarters

What is the task when finding a combination of coins that total three dollars?

• To find a point on the line labeled with 12 coins

• To find the midpoint of the graph

• To find a point on the line labeled with three dollars

• To find the intersection of the axes

What is unique about the solution that satisfies both 12 coins and three dollars?

• There are multiple solutions

• There is only one solution

• There are no solutions

• The solution is not on the graph

What should you do after finding the correct combination of coins?

• Submit your answer

• Recalculate the values

• Check the graph again

• Ask for help

What is the main goal of this lesson's cooldown activity?

• To learn about different types of coins

• To understand combinations of coins that meet specific conditions

• To draw a new graph

• To memorize the value of coins
