Course: Math 10, Workplace and Apprenticeship Metric and Imperial Measure Stage 1 – Desired Results Outcome: WA 10.3 and WA 10.4 Demonstrate using concrete, pictorial models, and symbolic representations, understanding of measurement systems including including units in the SI, Imperial and US customary systems of measurement (10.3 and 10.4) Indicators: -Describe relevant situations in which the SI and/or Imperial systems are used -Use strategies to approximate and convert a wide variety of units between the SI and Imperial systems -Use a wide variety of instruments to measure and record in both the SI and Imperial systems -Apply knowledge and skill to solve relevant problems involving linear measurement . Enduring Understandings: Students will understand that… Essential Questions: Depending where you live and on the task that you are doing there are different units of measurement appropriate for that task. How does what we measure influence how we measure How does how we measure influence what we conclude What units measure which quantities Why does more than one measurement system exist. Students will know: Students will do: Vocabulary of SI and Imperial units of measure. History of the SI and Imperial systems of measurement. SI system is based on decimals and the Imperial system is based on fractions. Relationships between SI prefixes and powers of 10 Strategies for the conversion of units within a system and to bridge systems. The uses of various tools for measuring and recording Performance Tasks: Generalize, explain, and apply strategies to convert measurements between the SI and Imperial systems. Measure and record linear measures with appropriate tools and units of measure. Provide approximate measurement to and from both SI and Imperial systems. Conversions within the same system of measurement. Stage 2 – Assessment Evidence Formative (Pre-assessment, Self, …) : 1)Building Design (finished cement floor) Floor is to have - infloor heating system - poured concrete floor - finished flooring Calculate (with appropriate units) from a set of blue prints and building specifications: Length and cost of piping to be installed for in floor heating system Using calipers and sample of piping calculate the volume and cost of coolant required for the infloor heating system Volume and cost of concrete for the poured floor Area required for finished flooring and a cost analysis for various types of flooring. 2) Grain volume (bins of various size and shapes or grain trailers) Using the appropriate tools measure and record the dimensions of a storage or transport container Calculate the volume of the container in both SI and Imperial units. Calculate the weight and value of various grains that could be in such a container. Homework questions Unit review Performance tasks Informal questioning/checking for understanding Journal writing Observations Summative Unit tests Quizes Performance Task(s) Stage 3 – Learning Plan Learning Activities: 1. Walking activity; Select a destination and ask students how far they think the distance is, what tools could be used to measure the distance and what time would it take to walk the distance. Discuss appropriate units for measurements. Measure the distance using a trundle, pedometer, measuring tape, odometer Record the walking time Discuss appropriateness and accuracy of measuring devices. Calculate the speed of the trip and meaning-full units 2. Jigsaw the history of measurement Teacher downloaded articles on the history of measurement, origins of SI and Imperial units of measure Students work in small groups to design and develop an oral and/or visual presentation on the history of measurements. 3. Using base 10 sets or Cubic centimeter lab explore the relationships between units of measuring surface area and volume. Discuss situations where these different units of volume are appropriate Solve problems involving conversion between SI units of volume Conversion between SI, Imperial, and US customary units of volume 4. Linear units of measure. Students measure a given object in various Imperial and SI units of linear measure. Students measure diameters of personally relevant 3D objects using calipers Students measure thicknesses of personally relevant 3D objects using a micrometer Discuss the relevance of use of precision instruments such as micrometers and calipers. Compare and contrast these measurements Students develop a method of conversion between SI and Imperial units Use developed methods to problem solve unit conversions. 5. Analyze various food items to compare and convert SI and Imperial units of weight measure. Students develop conversion factors based on weight labeling on various packaging Introduce tables of conversion factors Use tables of conversion factors to solve problems in unit conversions in both the SI and Imperial systems. Students perform a unit conversion task relevant to self and family at home and present problem to class. “Guess the weight” students guess masses of a variety of items in both the SI and Imperial systems. 6. Performance task of building construction. 7. Performance task on grain volume. 8. Learner generated examples Students create their own examples of problems to be solved by their classmates.
