I can see that thinking about “how much for 1” is useful for solving different types of problems.
Lesson 2: Anchoring Units of Measurement
When I read or hear a unit of measurement, I know whether it is used to measure length, weight, or volume.
I can name common objects that are about as long as 1 inch, foot, yard, mile, millimeter, centimeter, meter, or kilometer.
I can name common objects that weigh about 1 ounce, pound, ton, gram, or kilogram, or that hold about 1 cup, quart, gallon, milliliter, or liter.
Lesson 3: Measuring with Different-Sized Units
When I know a measurement in one unit, I can decide whether it takes more or less of a different unit to measure the same quantity.
Lesson 4: Converting Units
I know that when we measure things in two different units, the pairs of measurements are equivalent ratios.
I can convert measurements from one unit to another, using double number lines, tables, or by thinking about “how much for 1.”
Lesson 5: Comparing Speeds and Prices
I understand that if two ratios have the same rate per 1, they are equivalent ratios.
When measurements are expressed in different units, I can decide who is traveling faster or which item is the better deal by comparing “how much for 1” of the same unit.
Lesson 6: Interpreting Rates
I can choose which unit rate to use based on how I plan to solve the problem.
When I have a ratio, I can calculate its two unit rates and explain what each of them means in the situation.
Lesson 7: Equivalent Ratios Have the Same Unit Rates
I can give an example of two equivalent ratios and show that they have the same unit rates.
I can multiply or divide by the unit rate to calculate missing values in a table of equivalent ratios.
Lesson 8: More about Constant Speed
I can solve more complicated problems about constant speed situations.
Lesson 9: Solving Rate Problems
I can choose how to use unit rates to solve problems.
Lesson 10: What Are Percentages?
I can explain the meaning of percentages using dollars and cents as an example.
I can create a double number line with percentages on one line and dollar amounts on the other line.
Lesson 11: Percentages and Double Number Lines
I can use double number line diagrams to solve different problems like “What is 40% of 60?” or “60 is 40% of what number?”
Lesson 12: Percentages and Tape Diagrams
I can use tape diagrams to solve different problems like “What is 40% of 60?” or “60 is 40% of what number?”
Lesson 13: Benchmark Percentages
When I read or hear that something is 10%, 25%, 50%, or 75% of an amount, I know what fraction of that amount they are referring to.
Lesson 14: Solving Percentage Problems
I can choose and create diagrams to help me solve problems about percentages.
Lesson 15: Finding This Percent of That
I can solve different problems like “What is 40% of 60?” by dividing and multiplying.
Lesson 16: Finding the Percentage
I can solve different problems like “60 is what percentage of 40?” by dividing and multiplying.
Lesson 17: Painting a Room
I can apply what I have learned about unit rates and percentages to predict how long it will take and how much it will cost to paint all the walls in a room.
