Exploring Ratio Tables: Patterns and Missing Values

This video tutorial from Middlemath Academy covers the basics of ratio tables. It begins with an introduction to the learning targets, which include finding missing values, writing equivalent ratios, and identifying patterns in ratio tables. The lesson uses a smoothie recipe to illustrate these concepts, encouraging students to visualize and solve problems. The tutorial explains how to use ratio tables to represent data efficiently and provides practice problems to reinforce learning. Students are guided to identify and correct errors in ratio tables, and the session concludes with a reflection on the learning process.

What are the learning targets for this lesson?

• Learning about fractions, decimals, and percentages.

• Exploring geometric shapes and their properties.

• Finding the missing value in a ratio table, writing equivalent ratios, and identifying patterns.

• Understanding algebraic expressions and equations.

If a smoothie recipe calls for 2 cups of orange juice and 3 cups of blueberries, how many cups of orange juice are needed for two smoothies?

• 4 cups

• 2 cups

• 3 cups

• 6 cups

Why might drawing a picture to determine ingredients for 300 smoothies be challenging?

• It would be too time consuming.

• It would be too expensive.

• It would require too many colors.

• It would be too confusing.

What is the purpose of a ratio table?

• To convert fractions to decimals.

• To measure geometric shapes.

• To solve algebraic equations.

• To visualize the relationship between two quantities.

In a ratio table, if you have 2 cups of orange juice and 3 cups of blueberries, what would be the equivalent ratio for 6 cups of orange juice?

• 12 cups of blueberries

• 6 cups of blueberries

• 15 cups of blueberries

• 9 cups of blueberries

What is the value of the ratio if you have 3 cups of orange juice and 9 cups of blueberries?

• 4

• 3

• 2

• 1.5

If the ratio of dogs to cats is 2 to 8, what is the multiplication number sentence?

• Dogs times 8 equals cats

• Dogs times 6 equals cats

• Dogs times 4 equals cats

• Dogs times 2 equals cats

In a ratio table, if you have 3 brownies and 12 chocolate chips, what is the value of the ratio?

• 2

• 3

• 5

• 4

What should be the correct number of oranges if 8 bananas correspond to 50 oranges in a ratio table?

• 60

• 50

• 40

• 30

What is a common mistake students might make when working with ratio tables?

• All of the above.

• Forgetting to multiply both sides of the ratio.

• Using the wrong multiplication factor.

• Not labeling the table correctly.
