Measurement ManiaIn this lesson, students will practice converting measurement units within the metric system of measurement, and converting measurement units within the customary system of mon Core StandardConvert like measurement units within a given measurement system.5.MD.1 Convert among different-sized standard measurement units within a given measurement system (e.g., convert 5 cm to 0.05 m), and use these conversions in solving multi-step, real world problems.Additional/Supporting Standard:5.NBT.1 Explain the patterns in the place value system from one million to the thousandths place.? Explain that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left.? Explain patterns in products and quotients when numbers are multiplied by 1,000, 100, 10, 0.1, and 0.01 and/or divided by 10 and 100.Standards for Mathematical Practice:6. Attend to precision7. Look for and make use of structure8. Look for and express regularity in repeated reasoningStudent Outcomes:I can convert measures within the same systemI can explain why my answers make senseMaterials:One game board, set of cards, and answer sheet for each group of 3 studentsOne die for each group of 3 studentsItems to use as markers for each group of studentsAdvance Preparation:Copy the game board and set of cards. Laminating them on cardstock will help the materials last longer. Cut out each set of 20 cards and store in a baggie.Copy an answer sheet for each groupPlace markers for each group in the baggie of cardsConsider how you will group studentsStudents should have ample experience exploring the meanings of cm, m, km, g, kg, ml, L, oz, lb, in, ft, and yd.Students should be familiar with strategies for converting measures within the same system.Directions:This game provides practice for converting measures. There are two options for game play:Option 13 students play the game with one serving as the Answer Person and the other two solving the problems. The answer person uses the Measurement Mania Answers sheet and acts as supervisor. The Answer Person does not roll the die or move a marker.Option 23 students play the game. The students take turns being the Answer Person and using the Answer Person, switching to a new person on each turn.Questions to Pose:Before:What strategies can you use for converting measures?How are cm, m, and km related? How are oz and lb related?How can you make sure that your answer makes sense?During:What strategy did you use to convert the measures?How can you tell that your answer makes sense?What error did you make? How can you prevent this error in the future?After:What strategies worked especially well for you? Why were they so effective?What errors did you make frequently? How can you prevent these errors in the future?How might it help to visualize the unit in your mind?How might it help to use a benchmark?How might it help to think about 10s, 100s, and 1000s?Possible Misconceptions/Suggestions:Possible MisconceptionsSuggestionsStudents have difficulty remembering how the units are related to one another.Use objects and measuring tools to explore the base units. For instance, on a meter stick how many centimeters are equivalent to a meter?Engage the students in activities to establish benchmarks. What can they use to remember the size of a gram?Through classroom tasks, develop a chart to explore how measures are related. For instance 2 m = 200 cm and 3 m = 300 cm, therefore meters are 100 times the size of centimeters.Special Notes:This game is intended for practice. Students should not practice the procedures for conversion until they have had ample opportunities to explore measurement units and relationships.Solutions:See Measurement Mania AnswersMeasurement Mania#1.1 cm =m#2.1 kg =g#3.1 m =cm#41 L =____ml#5100 cm =m#61 km =m#71000 m=__km#81 lb =oz#93 ft =____in#109 yd =ft#114.2 m =__cm#123000 ml =____L#1332 oz =lb#145 cm =__m#15200 m =__km#16500 g =__kg#1745.6 cm =___m#1836 in =__ft#19150 ft =yd#203.2 kg =__gMeasurement Mania Answers1 cm = 0.01 m1 kg = 1000 g1 m = 100 cm1 L = 1000 ml100 cm = 1 m1 km = 1000 m1000 m = 1 km1 lb = 16 oz3 ft = 36 in9 yd = 27 ft4.2 m = 420 cm3000 ml = 3 L32 oz = 2 lb 14.5 cm = 0.05 m200 m = 0.2 km500 g = 0.5 kg45.6 cm = 0.456 m36 in = 3 ft 19.150 ft = 30 yd3.2 kg = 3200 g ................
