Activity Overview

Students solve a problem involving mixing of paint colors. They use color charts to determine the fractional parts and percentages of colors needed to create tints and shades.

Before the Activity

  • See the attached PDF file for detailed instructions for this activity
  • Print pages 78 - 86 from the attached PDF file for your class
  • Review the four steps of problem solving with the students

    		•

    		During the Activity

    		Distribute the pages to the class.

    Follow the activity procedures:
  • Read the problem and understand how tints and shades are prepared
  • Create a tint and shade chart for one color
  • Calculate the amount of each color paint used for each tint or shade
  • Create a chart showing the fractional amount, percentages, and actual number of liters of each color of paint needed to make a batch of each tint or shade
  • Write an explanation about the calculations used


    • Converting fractions to percents
  • Solve problems involving conversion of fractions to percents

    		After the Activity

    		Students analyze different ways in which they used the calculator to solve the problem.
