Understanding Ratios and Paint Mixtures

Mrs. Nelson introduces a lesson on representing ratios with diagrams. The objective is to draw and explain diagrams that represent ratios. Using Elena's paint mixture as an example, the lesson covers writing ratio sentences, reversing ratios, and scaling them down. The importance of phrasing and order in ratio sentences is emphasized, with practical examples provided. The lesson concludes with a recap of the objectives.

What is the main objective of this lesson?

• To learn how to mix paints

• To understand how to draw and explain diagrams representing ratios

• To calculate the cost of paint

• To learn about different types of paint

In Elena's paint mixture, how many tablespoons of blue paint are used with 2 cups of white paint?

• 5 tablespoons

• 4 tablespoons

• 7 tablespoons

• 6 tablespoons

How can the ratio of cups of white paint to tablespoons of blue paint be expressed?

• 3 to 6

• 2 to 6

• 1 to 3

• 2 to 5

What happens to the ratio when you reverse the order of the items?

• The ratio becomes zero

• The ratio becomes negative

• The order of numbers in the ratio is reversed

• The ratio remains the same

If you want to make half of Elena's paint mixture, how many cups of white paint would you use?

• 1 cup

• 4 cups

• 3 cups

• 2 cups

What phrase is used to describe the smallest possible grouping of a ratio?

• For some

• For all

• For every

• For each

How would you express the ratio of 1 cup of white paint to 3 tablespoons of blue paint?

• 3 to 1

• 2 to 3

• 1 to 3

• 1 to 2

What must be ensured when reversing the words in ratio sentences?

• The words should be reversed to match the ratio order

• The words should be in alphabetical order

• The words should be omitted

• The words should be in the same order

What is the correct order of labels in a ratio sentence?

• Based on the color of the paint

• Based on the alphabetical order

• Based on the order of the ratio

• Based on the length of the words

What is the final objective reiterated at the end of the lesson?

• To draw a diagram that represents a ratio and explain it

• To memorize paint colors

• To learn about different types of diagrams

• To calculate the cost of paint
