OSEU 7Mathematics

Grade level: Grade 6, Grade 7, Grade 8

Middle school collection; specific grade not stated.

Archived standards are preserved as originally published and may differ from current standards.

Compelling question

How can one type of unit of measure be converted to another unit of measure?

Standards & practices

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. Practice 4: Model with mathematics. 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 question

How can we convert a length of time like a “Moon” in Native American terminology to another unit of time like days?

Supporting inquiries

Supporting question 1

How can we compare an amount of one unit to an equal amount of another?

Formative performance task

Steps for solving a conversion problem: 1. Determine the given units and the units we want to find. Will it take one step or many? 2. State the equivalent units such as “one Native American ‘moon’ equals 28 days. 1 moon = 28 days 3. Divide the equivalent values by each other to get a quotient of 1. 1 moon/28 days = 1 or 28 days = 1 moon 4, Multiply the given unit value by the division problem so that the given units cancel out and the wanted units remain. Ex. Convert 168 days to moons 168 days X 28 days/1 moon = 6 moons

Supporting question 2

How do we change from one type of unit to another type of unit without destroying the initial value?

Formative performance task

Convert 10 cups drinking water to gallons. Step 1: Given units (10 cups). Wanted units (gallons). Step 2: 1 gallon = 16 cups Step 3: 1 gal/16 cups or 16 cups/1 gal Step 4: 10 cups X 1 gal/16 cups = .625 Gallons

Supporting question 3

Can we use a model to convert any unit value to any other unit value?

Formative performance task

Write the 4 steps to solving unit conversion problems. Step 1: Given units and wanted unit Step 2: State equivalent units Step 3: Divide equivalent values by each other to get a quotient of 1. Step 4: Multiply the given units by the division problem that will cancel given units and leave the wanted units.
