Ratios and Proportional Relationships

6.RP.A.1

What the standard says

Understand the concept of a ratio and use ratio language to describe a relationship between two quantities.

What this means

I can compare two amounts using a ratio.

A ratio tells how much of one thing there is compared with another thing.

Example

If there are 3 cats and 5 dogs, the ratio of cats to dogs is 3 to 5.

The ratio of dogs to cats is 5 to 3, and the ratio of cats to all animals is 3 to 8.

In normal student words

I can compare two quantities and say what the comparison means.

6.RP.A.2

What the standard says

Understand the concept of a unit rate associated with a ratio.

What this means

I can find how much there is for 1 of something.

A unit rate is a rate in which the second number is 1.

Example

If 4 notebooks cost $12, then 1 notebook costs $3.

The unit rate is $3 per notebook.

In normal student words

I can figure out the “for one” amount.

6.RP.A.3

What the standard says

Use ratio and rate reasoning to solve real-world and mathematical problems.

What this means

I can use ratios, tables, double number lines, tape diagrams, and equations to solve problems.

This includes percent problems, unit rates, measurement conversions, and equivalent ratios.

Example

If 5 tickets cost $20, I can use a ratio table to find the cost of 8 tickets.

In normal student words

I can use ratios to solve actual problems, not just stare at two numbers and hope they behave.

The Number System

6.NS.A.1

What the standard says

Interpret and compute quotients of fractions, and solve word problems involving division of fractions by fractions.

What this means

I can find greatest common factors and least common multiples.

I can use the distributive property to rewrite expressions.

Example

The GCF of 24 and 36 is 12. The LCM of 4 and 6 is 12.

In normal student words

I can find common factors, common multiples, and rewrite numbers using shared factors.

6.NS.C.5

What the standard says

Understand that positive and negative numbers are used together to describe quantities having opposite directions or values.

What this means

I can understand positive and negative numbers in real-life situations.

Example

+10 can mean 10 feet above sea level; −10 can mean 10 feet below sea level.

In normal student words

I can understand numbers on both sides of zero.

6.NS.C.6

What the standard says

Understand a rational number as a point on the number line. Extend number line diagrams and coordinate axes to represent points with negative coordinates.

6.NS.C.7

What the standard says

Understand ordering and absolute value of rational numbers.

What this means

I can compare positive and negative numbers.

In normal student words

I can use exponents without thinking 3⁴ means 3 × 4, because nope.

6.EE.A.2

What the standard says

Write, read, and evaluate expressions in which letters stand for numbers.

What this means

I can work with variables.

I can write expressions from words and evaluate them when I know the value of the variable.

I can tell when two expressions are secretly the same thing wearing different outfits.

6.EE.B.5

What the standard says

Understand solving an equation or inequality as answering a question about which values make it true.

6.G.A.2

What the standard says

Find the volume of a right rectangular prism with fractional edge lengths.

What this means

I can find volume using length × width × height, even when the side lengths are fractions.

Example

A prism has side lengths 1/2, 3, and 4. Its volume is 1/2 × 3 × 4 = 6 cubic units.

In normal student words

I can find how much space a box takes up, even when fractions sneak in.

Statistics and Probability

6.SP.A.1

What the standard says

Recognize a statistical question as one that expects variability in the data.

What this means

I can tell whether a question is statistical.

A statistical question has many possible answers that can vary.

Example

Statistical: How many minutes do students in our class spend on homework each night?

Not statistical: How many minutes are in one hour?

In normal student words

I can tell whether a question will give different answers from different people.

6.SP.A.2

What the standard says

Understand that a set of data has a distribution that can be described by its center, spread, and overall shape.

What this means

I can describe data by looking at what is typical, how spread out it is, and what the graph looks like.

Example

I can describe whether most data values are close together or spread far apart.

In normal student words

I can describe what a data set looks like instead of just saying, “There are numbers.”

6.SP.A.3

What the standard says

Recognize that a measure of center summarizes all values with a single number, while a measure of variation describes how values vary.

What this means

I can understand the difference between center and spread.

Measures of center include mean and median. Measures of variation include range and interquartile range.

Example

The mean describes a typical value; the range describes how spread out the data is.

In normal student words

I can tell what is typical and how spread out the data is.

6.SP.B.4

What the standard says

Display numerical data in plots on a number line, including dot plots, histograms, and box plots.

Summarize numerical data sets in relation to their context.

What this means

I can summarize data by describing the number of data points, center, spread, shape, and what the data means.

Example

The data shows that most students studied between 20 and 40 minutes. The median was 30 minutes, and there was one high outlier.

In normal student words

I can explain what the data tells us using numbers and words.

Big idea

Math is connected.

Grade 6 math is about learning how numbers, operations, expressions, shapes, and data work together. By the end of the year, students should be able to solve problems, explain their thinking, use models, and check whether answers make sense.

This is when math moves beyond “do the steps” and starts asking, “Do you understand what you just did?”
