Ohio 7th Grade Math Standards

All 23 Ohio math standards for 7th grade, each explained in plain English. The official wording is in Ohio Department of Education and Workforce's document, linked at the end of this page.

23 standards

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 real-world and math problems that add, subtract, multiply, and divide positive and negative fractions and decimals, including complex fractions.

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
Rewrite an expression in a new form to show what it means in a problem, like seeing a 20% discount p − 0.2p is the same as 0.8p, or 80% of the price.
7.EE.3
Solve multi-step problems with positive and negative whole numbers, fractions, and decimals, switching forms as needed and checking by estimating, like a 10% raise on $20.
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
Solve similar-figure problems with triangles and special quadrilaterals, finding real lengths and areas from scale drawings, redrawing at new scales, and showing proportions.
7.G.2
Draw triangles and quadrilaterals from given angles or sides by hand, with tools, or on a computer, noting when the facts give one shape, several, or none.
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
Explore links among a circle's radius, diameter, circumference, and area, and know and apply the area and circumference formulas in real-world and math problems.
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 the area of polygons and the volume and surface area of prisms, including shapes built from several pieces.
Common Core 7.G.6

Statistics and Probability

7 standards
7.SP.1
Use a sample to learn about a whole population, tell the two apart, and see that conclusions only hold for a sample that fairly represents the group, noticing bias.
7.SP.2
Carry out a full statistics study, posing a question like how seventh and eighth graders' heights compare, gathering and analyzing data, and making generalizations.
7.SP.3
Describe data with mean absolute deviation, seeing the mean as a balance point, and judge how much two data sets overlap by comparing their centers to their spread.
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 compound events, like rolling two sixes, by listing outcomes in lists, tables, or tree diagrams and by designing simulations.
