32 standards

Standards for Mathematical Practice

8 standards
7.SMP.1
Work through proportional reasoning and multi-step percent problems, like tax, tip and discount, persisting and checking answers.
7.SMP.2
Translate between contexts and expressions with rational numbers, like writing -15 + 9 for a temperature change and explaining what it means.
7.SMP.3
Make and defend arguments about proportional relationships, probability or equations, and evaluate others' work by finding flaws or strengths.
7.SMP.4
Represent situations with equations, inequalities, scale drawings and probability models, like using a scale to find a real room's size.
7.SMP.5
Choose tools such as protractors, calculators, graphs and simulations, like running a coin flip simulation to estimate a probability.
7.SMP.6
Use exact vocabulary and notation for negatives, percents and units, and round answers sensibly, like giving money to the nearest cent.
7.SMP.7
Use structure to rewrite expressions, like seeing a + 0.05a as 1.05a to show a 5% increase.
7.SMP.8
Notice patterns in repeated computations, like a constant ratio in a table that points to a proportional relationship.

Ratios and Proportional Relationships

3 standards
7.RP.1
Find a unit rate from a ratio of fractions, like 1/2 mile in 1/4 hour is 2 miles per hour.
Common Core 7.RP.1
7.RP.2
Decide whether two quantities are proportional, find the constant of proportionality, and write the relationship as an equation like t = pn.
Common Core 7.RP.2
7.RP.3
Solve multi-step percent problems about tax, tips, discounts, simple interest and percent change.
Common Core 7.RP.3

The Number System

3 standards
7.NS.1
Add and subtract positive and negative numbers, including fractions and decimals, knowing that subtracting a number is adding its opposite.
Common Core 7.NS.1
7.NS.2
Multiply and divide positive and negative numbers, including the sign rules, and turn any fraction into a decimal that ends or repeats.
Common Core 7.NS.2
7.NS.3
Solve word problems that mix all four operations with positive and negative fractions and decimals.
Common Core 7.NS.3

Expressions and Equations

4 standards
7.EE.1
Combine, factor and expand linear expressions, like rewriting 3(x + 2) as 3x + 6 or 2x + 5x as 7x.
Common Core 7.EE.1
7.EE.2
See what a rewritten expression reveals, like a + 0.05a = 1.05a showing that a 5% increase is the same as multiplying by 1.05.
Common Core 7.EE.2
7.EE.3
Solve multi-step problems with positive and negative whole numbers, fractions and decimals, switching forms as needed and checking answers by estimating.
Common Core 7.EE.3
7.EE.4
Write and solve two-step equations like 3x + 5 = 20 and inequalities like 3x + 5 > 20 from word problems, and graph the inequality's solutions.
Common Core 7.EE.4

Geometry

6 standards
7.G.1
Use scale drawings to find real lengths and areas, and redraw a figure at a different scale.
Common Core 7.G.1
7.G.2
Draw shapes from given measurements, and tell whether three side or angle measures make one triangle, many, or none.
Common Core 7.G.2
7.G.3
Describe the flat shape you get when you slice through a rectangular box or pyramid.
Common Core 7.G.3
7.G.4
Use the formulas for the circumference and area of a circle, and explain how the two are connected.
Common Core 7.G.4
7.G.5
Find an unknown angle by writing an equation from angle facts, like two angles on a straight line adding to 180 degrees.
Common Core 7.G.5
7.G.6
Find area, volume and surface area in real-world and math problems for shapes built from triangles, quadrilaterals and other polygons, including cubes, right prisms and pyramids.

Statistics and Probability

8 standards
7.SP.1
Understand that a random sample can tell you about a whole population, but only if the sample fairly represents it.
Common Core 7.SP.1
7.SP.2
Use a random sample to estimate something about a population, and take several samples to see how much the estimate might vary.
Common Core 7.SP.2
7.SP.3
Judge how much two data sets with similar spread overlap by expressing the gap between their centers as a multiple of the spread, like on side-by-side dot plots.
7.SP.4
Compare two populations informally using the centers and interquartile ranges of random samples, like whether one book's words are generally longer than another's.
7.SP.5
Know that a probability is a number from 0 to 1, where near 0 means unlikely, 1/2 means as likely as not, and near 1 means likely.
Common Core 7.SP.5
7.SP.6
Estimate a probability from many trials, and predict outcomes from a probability, like rolling a 3 or 6 about 200 times in 600 rolls.
Common Core 7.SP.6
7.SP.7
Build a probability model, either with equally likely outcomes or from observed data, and explain when results do not match it.
Common Core 7.SP.7
7.SP.8
Find the probability of a compound event, like rolling double sixes, by listing outcomes in a table or tree diagram or by running a simulation.
Common Core 7.SP.8
