KY.7.RP: Ratios and Proportional Relationships

1.1: Analyze proportional relationships and use them to solve real-world and mathematical problems.

KY.7.RP.1: Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units.

KY.7.RP.2: Recognize and represent proportional relationships between quantities.

KY.7.RP.3: Use percents to solve mathematical and real-world problems.

KY.7.NS: The Number System

2.1: Apply and extend previous understandings of operations with fractions to add, subtract, multiply and divide rational numbers.

KY.7.NS.1: Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagram.

KY.7.NS.2: Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers.

KY.7.NS.3: Solve real-world and mathematical problems involving the four operations with rational numbers.

KY.7.EE: Expressions and Equations

3.1: Use properties of operations to generate equivalent expressions.

KY.7.EE.1: Apply properties of operations as strategies to add, subtract, factor and expand linear expressions with rational coefficients.

KY.7.EE.2: Understand that rewriting an expression in different forms in a problem context can clarify the problem and how the quantities in it are related.

3.2: Solve real-life and mathematical problems using numerical and algebraic expressions and equations.

KY.7.EE.3: Solve real-life and mathematical problems posed with positive and negative rational numbers in any form, using tools strategically. Apply properties of operations to calculate with numbers in any form; convert between forms as appropriate; and assess the reasonableness of answers using mental computation and estimation strategies.

KY.7.EE.4: Use variables to represent quantities in a real-world or mathematical problem and construct equations and inequalities to solve problems by reasoning about the quantities.

KY.7.G: Geometry

4.1: Draw, construct and describe geometrical figures and describe the relationships between them.

KY.7.G.1: Solve problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at a different scale.

KY.7.G.2: Draw (freehand, with ruler and protractor and with technology) geometric shapes with given conditions. Focus on constructing triangles from three measures of angles or sides, noticing when the conditions determine a unique triangle, more than one triangle, or no triangle.

KY.7.G.3: Describe the two-dimensional figures that result from slicing three-dimensional figures, as in plane sections of right rectangular prisms and right rectangular pyramids.

4.2: Solve real-life and mathematical problems involving angle measure, area, surface area and volume.

KY.7.G.4: Use formulas for area and circumference of circles and their relationships.

KY.7.G.5: Apply properties of supplementary, complementary, vertical and adjacent angles in a multi-step problem to write and solve simple equations for an unknown angle in a figure.

KY.7.G.6: Solve problems involving area of two-dimensional objects and surface area and volume of three-dimensional objects.

KY.7.SP: Statistics and Probability

5.1: Use random sampling to draw inferences about a population.

KY.7.SP.0: Create displays, including circle graphs (pie charts), scaled pictographs and bar graphs, to compare and analyze distributions of categorical data from both matching and different-sized samples.

KY.7.SP.1: Understand that statistics can be used to gain information about a population by examining a sample of the population; generalizations about a population from a sample are valid only if the sample is representative of that population. Understand that random sampling tends to produce representative samples and support valid inferences.

KY.7.SP.2: Use data from a random sample to draw inferences about a population with an unknown characteristic of interest.

5.2: Draw informal comparative inferences about two populations.

KY.7.SP.3: Describe the degree of visual overlap (and separation) from the graphical representations of two numerical data distributions (box plots, dot plots) with similar variabilities with similar contexts (same variable), measuring the difference between the centers (medians or means) by expressing this difference as a multiple of a measure of variability (interquartile range when comparing medians or the mean absolute deviation when comparing means).

KY.7.SP.4: Calculate and use measures of center (mean and median) and measures of variability (interquartile range when comparing medians and mean absolute deviation when comparing means) for numerical data from random samples to draw informal comparative inferences about two populations.

5.3: Investigate chance processes and develop, use and evaluate probability models.

KY.7.SP.5: Describe the probability of a chance event is a number between 0 and 1, which tells how likely the event is, from impossible (0) to certain (1). A probability near 0 indicates an unlikely event, a probability around 1/2 indicates an event that is neither unlikely nor likely and a probability near 1 indicates a likely event.

KY.7.SP.6: Approximate the probability of a chance event by collecting data on the chance process that produces it and observing its long-run relative frequency and predict the approximate relative frequency given the probability.

KY.7.SP.7: Develop a probability model and use it to find probabilities of events. Compare probabilities from a model to observed frequencies; if the agreement is not good, explain possible sources of the discrepancy.

KY.7.SP.8: Find probabilities of compound events using organized lists, tables, tree diagrams and simulation.
