MS7MAEE02000MS7-MA-EE.02.00.0Understand that rewriting an expression in different forms in a
problem context can shed light on the problem and how the quantities in it are related. (e.g., a + 0.05a = 1.05a means that “increase by 5%” is the same as “multiply by 1.05.”

MS7MAEE04A0MS7-MA-EE.04.A.0Solve word problems leading to equations of the form px + q = r
and p(x + q) = r, where p, q, and r are specific rational numbers.
Solve equations of these forms fluently. Compare an algebraic
solution to an arithmetic solution, identifying the sequence of the
operations used in each approach. For example, the perimeter of a
rectangle is 54 cm. Its length is 6 cm. What is its width?

MS7MAEE04B0MS7-MA-EE.04.B.0Solve word problems leading to inequalities of the form px + q > r
or px + q < r, where p, q, and r are specific rational numbers. Graph
the solution set of the inequality and interpret it in the context of
the problem. For example: As a salesperson, you are paid $50 per
week plus $3 per sale. This week you want your pay to be at least
$100. Write an inequality for the number of sales you need to make,
and describe the solutions.

MS7MASP01000MS7-MA-SP.01.00.0Understand 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.Data Analysis, Probability & Statistics
33
MS7MASP02000MS7-MA-SP.02.00.0Use data from a random sample to draw inferences about a population with an unknown characteristic of interest. Generate multiple samples (or simulated samples) of the same size to gauge the variation in estimates or predictions. (e.g., estimate the mean word length in a book by randomly sampling words from the book; predict the winner of a school election based on randomly sampled survey data. Gauge how far off the estimate or prediction might be.Data Analysis, Probability & Statistics
34
MS7MASP03000MS7-MA-SP.03.00.0Informally assess the degree of visual overlap of two numerical data distributions with similar variabilities, measuring the difference between the centers by expressing it as a multiple of a measure of variability. (e.g., the mean height of players on the basketball
team is 10 cm greater than the mean height of players on the soccer team, about twice the variability (mean absolute deviation) on either team; on a dot plot, the separation between the two distributions of heights is noticeable.

37
MS7MASP06000MS7-MA-SP.06.00.0Approximate 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.

39
MS7MASP07A0MS7-MA-SP.07.A.0Develop a uniform probability model by assigning equal
probability to all outcomes, and use the model to determine
