6th GradeProportions and Ratios60 minute connection2 sites per connectionProgram DescriptionClassroom PreparationMath Mania Proportions and Ratios reviews themathematical concepts of multiplication,division, ratios, percents, and proportions.Students will compete with other classes tosolve math problems. Problems will bepresented in a game show format. Problemsolving strategies will be discussed andemphasized.Materials Print and bring to the conference the FINALQUESTION and READY sign, one copy ofeach per group (pgs 4-5)Learning Objectives*Suggested Room Arrangement for Connection Organize your students into small groups of4-5 students for the session. Your class will need a team name (1 namefor the class). Have a designated place for a student tostand on camera for the FINAL QUESTION. Make sure all students have materials forproblem solving, such as several pieces ofpaper and pencil. Small dry erase boardsare recommended, if available.Students will Use multiplication and division of wholenumbers to solve problems includingsituations involving equivalent ratios andrates Use ratios to describe proportionalsituations Represent ratios and percents withconcrete models, fractions and decimals Use ratios to make predictions inproportional situations Use tables and symbols to represent anddescribe proportional and otherrelationships such as those involvingconversions, arithmetic sequences (with aconstant rate of change), perimeter andareaVocabularyratio, proportion, rate, percent 2012 WhirlidurbPre-connection ActivitiesReview the problem solving strategies listed inthe “Mathematical Processes” section locatedon page 2.Lesson Sequence(during video conference) Greetings and Ground RulesMath Mania game show (up to 15 problemspossible)DebriefGoodbyes
