“Math: Converting from one unit to another” | OSEU 7: Way of Life & Development Compelling How can one type of unit of measure be converted to another unit of measure? Question South Dakota Common Core State Standards for Mathematics. Practice 1: Make sense of problems an persevere in solving them. Practice 2: Reason abstractly and quantitatively. Standards and Practice 4: Model with mathematics. Practices Practice 6: Attend to precision. Practice 7: Look for and make use of structure. Practice 8: Look for and express regularity in repeated reasoning. Staging the How can we convert a length of time like a “Moon” in Native American terminology to another unit Question of time like days? Supporting Question 1 Supporting Question 2 Supporting Question 3 How can we compare an amount of How do we change from one type of Can we use a model to convert any one unit to an equal amount of unit to another type of unit without unit value to any other unit value? another? destroying the initial value? Formative Performance Task Formative Performance Task Formative Performance Task Steps for solving a conversion problem: 1. Determine the given units and the units we want to find. Will it take Write the 4 steps to solving unit Convert 10 cups drinking water to conversion problems. one step or many? gallons. 2. State the equivalent units such as “one Native American ‘moon’ Step 1: Given units and wanted unit equals 28 days. 1 moon = 28 days Step 1: Given units (10 cups). Wanted 3. Divide the equivalent values by units (gallons). Step 2: State equivalent units each other to get a quotient of 1. Step 3: Divide equivalent values by 1 moon/28 days = 1 or Step 2: 1 gallon = 16 cups each other to get a quotient of 1. 28 days = 1 moon Step 3: 1 gal/16 cups or 16 cups/1 gal Step 4: Multiply the given units by 4, Multiply the given unit value by Step 4: the division problem that will cancel the division problem so that the given given units and leave the wanted units cancel out and the wanted units 10 cups X 1 gal/16 cups = .625 Gallons units. remain. Ex. Convert 168 days to moons 168 days X 28 days/1 moon = 6 moons Featured Sources Featured Sources Featured Sources GO MATH Grade 6 (2015) , pg 315-332 Prentice Hall “Physical Science by Houghton Mifflin Harcourt Concepts in Action With Earth and Publishing Company.
