Kentucky 7th Grade Math Standards

All 25 Kentucky math standards for 7th grade, each explained in plain English. The official wording is in Kentucky Department of Education's document, linked at the end of this page.

25 standards

Ratios and Proportional Relationships

3 standards
KY.7.RP.1
Find unit rates from ratios of fractions, like walking 1/2 mile in 1/4 hour means 2 miles per hour, with lengths, areas, and other units.
KY.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
KY.7.RP.3
Find a percent of an amount as a rate per 100, find the whole, part, or percent from the other two, and solve multistep ratio and percent problems like tax and discounts.

The Number System

3 standards
KY.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
KY.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
KY.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
KY.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
KY.7.EE.2
Explain how writing an expression a different way can make a problem clearer, like a + 0.05a as 1.05a showing a 5% increase.
KY.7.EE.3
Solve real problems with positive and negative fractions, decimals, and percents, choosing tools wisely, converting between forms, and checking answers by estimating.
KY.7.EE.4
Turn word problems into equations like 3x + 5 = 20 or 2(x + 4) = 18 and inequalities like 3x + 5 > 20, solve them, graph the solutions, and explain them in context.

Geometry

6 standards
KY.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
KY.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
KY.7.G.3
Describe the flat shape you get when you slice through a rectangular box or pyramid.
Common Core 7.G.3
KY.7.G.4
Use the area and circumference formulas for circles to solve problems, and explain how radius, diameter, circumference, and area are related.
KY.7.G.5
Use facts about supplementary, complementary, vertical, and adjacent angles to write and solve simple equations for a missing angle in multistep problems.
KY.7.G.6
Solve real problems finding the area of shapes made of triangles and other polygons, and the volume and surface area of cubes, pyramids, and right prisms using nets.

Statistics and Probability

9 standards
KY.7.SP.0
Make circle graphs, scaled picture graphs, and bar graphs to compare category data from samples of the same or different sizes.
KY.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
KY.7.SP.2
Draw conclusions about a population from random samples, running several samples or simulations of category and number data to judge how much and how far estimates may vary.
KY.7.SP.3
Judge how much two similar data sets overlap on box plots or dot plots, and express the gap between their centers as a multiple of their spread.
KY.7.SP.4
Use the mean, median, interquartile range, and mean absolute deviation of random samples to make informal comparisons between two populations.
KY.7.SP.5
Describe probability as a number from 0 for impossible to 1 for certain, where values near 0 are unlikely, near 1/2 are a toss-up, and near 1 are likely.
KY.7.SP.6
Estimate a probability by repeating a chance process many times, and predict results from a probability, like rolling a 3 about 100 times in 600 rolls.
KY.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
KY.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
