Color Mixtures and Ratios

Mrs. Nelson presents a math lesson for sixth graders on equivalent ratios using a color mixture example. The lesson focuses on creating 'perfect purple water' by mixing specific amounts of blue and red water. Jada's and Andrei's mixtures are analyzed to determine if they match the original recipe's shade. The lesson concludes by explaining how to find other equivalent ratios to achieve the same color shade, emphasizing the importance of maintaining proportional changes in recipes.

What is the main objective of the lesson on color mixtures?

• To learn how to paint with watercolors

• To understand the concept of equivalent ratios using color mixtures

• To mix different colors to create new shades

• To calculate the volume of water needed for painting

What is the recipe for creating perfect purple water?

• 8 ml of blue water and 3 ml of red water

• 6 ml of blue water and 4 ml of red water

• 10 ml of blue water and 2 ml of red water

• 5 ml of blue water and 5 ml of red water

How did Jada ensure her mixture was the same shade as the perfect purple water?

• By doubling the amount of blue water

• By tripling both the blue and red water amounts

• By adding more red water than blue

• By using a different ratio of blue to red

How many times did Jada multiply the original recipe to get her mixture?

• Two times

• Five times

• Three times

• Four times

Why does Andre's mixture result in a different shade of purple?

• He used less blue water than required

• He used the same amount of blue and red water

• He doubled the blue water but tripled the red water

• He used more blue water than red

What is an equivalent ratio in the context of color mixtures?

• A ratio that uses different colors

• A ratio that uses more water overall

• A ratio that maintains the same shade by scaling both parts equally

• A ratio that changes the shade by altering one part

If you double the amount of blue water in the recipe, what must you do to the red water to maintain the same shade?

• Triple it

• Double it as well

• Keep it the same

• Reduce it by half

What would be the total amount of blue water if Jada's triple batch is doubled?

• 60 ml

• 48 ml

• 36 ml

• 24 ml

What is the result of making six batches of the original recipe?

• A different shade of purple

• The same shade but with more volume

• A lighter shade of purple

• A darker shade of purple

What happens if you change only one part of the recipe?

• The mixture becomes less vibrant

• The shade remains the same

• The shade changes

• The mixture becomes more vibrant
