S.                               6130 S Wolcott Ave.                               Chicago, Ill. 60636                               312-471-8700     Objective:Ninth grade students will be able to write the equation and solve mixture problems. Equipment and Materials:1. Overhead Projector2. 100 red and 100 yellow beads for each group of 4 students3. 1 container for each group4. 1 calculator for each group5. 5 small cups for each groupRecommended Strategies:1. Students will count out 4 cups of beads that are 40% red (a cup contains 15    beads) and place the beads in a container.2. Students will count out 2 cups of beads that are 80% red and add this    mixture to the container until the beads in the container are 50% red.3. Students will complete the following table.Original Mixture                   Add                    New Mixture(Percent)(Amount)            (Percent)(Amount)         (percent)(Amount)________________              _______________    =      _______________                                                        4. Students will solve the next two problems by repeating the steps above.   a. Change 8 cups of beads that are 50% red to 60% red by adding 100% red       beads.   b. Change 4 cups that are 20% red to 15% red by adding yellow beads.5. Student will solve additional problems by letting x = amount added.`
