- 7.NS.2Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers
- 7.NS.2aUnderstand that multiplication is extended from fractions to rational numbers by requiring that operations continue to satisfy the properties of operations, particularly the distributive property, leading to products such as (–1)(–1) = 1 and the rules for multiplying signed numbers. Interpret products of rational numbers by describing real-world contexts
- 7.NS.2bUnderstand that integers can be divided, provided that the divisor is not zero, and every quotient of integers (with non-zero divisor) is a rational number. Ifpandqare integers, then –(p/q) = (–p)/q=p/(–q). Interpret quotients of rational numbers by describing real-world contexts

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
- 7.EE.4Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities
- 7.EE.4aSolve word problems leading to equations of the formpx+q=randp(x+q) =r, wherep,q, andrare 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

7.SP · Statistics & Probability
- 7.SPStatistics and Probability
- 7.SP.1Understand that statistics can be used to gain information about a population by examining a sample of the population
- 7.SP.1aDifferentiate between a sample and a population
- 7.SP.1bUnderstand that conclusions and generalizations about a population are valid only if the sample is representative of that population. Develop an informal understanding of bias
- 7.SP.2Broaden statistical reasoning by using the GAISE model:
- 7.SP.2aFormulate Questions: Recognize and formulate a statistical question as one that anticipates variability and can be answered with quantitative data
- 7.SP.2bCollect Data: Design and use a plan to collect appropriate data to answer a statistical question
- 7.SP.2cAnalyze Data: Select appropriate graphical methods and numerical measures to analyze data by displaying variability within a group, comparing individual to individual, and comparing individual to group
- 7.SP.2dInterpret Results: Draw logical conclusions and make generalizations from the data based on the original question
- 7.SP.3Describe and analyze distributions
- 7.SP.3aSummarize quantitative data sets in relation to their context by using mean absolute deviation (MAD), interpreting mean as a balance point
- 7.SP.3bInformally assess the degree of visual overlap of two numerical data distributions with roughly equal variabilities, measuring the difference between the centers by expressing it as a multiple of a measure of variability
- 7.SP.5Understand that the probability of a chance event is a number between 0 and 1 that expresses the likelihood of the event occurring. Larger numbers indicate greater likelihood. A probability near 0 indicates an unlikely event; a probability around ½ indicates an event that is neither unlikely nor likely; and a probability near 1 indicates a likely event
- 7.SP.6Approximate 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
- 7.SP.7Develop 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
- 7.SP.7aDevelop a uniform probability model by assigning equal probability to all outcomes, and use the model to determine probabilities of events
- 7.SP.7bDevelop a probability model (which may not be uniform) by observing frequencies in data generated from a chance process
- 7.SP.8Find probabilities of compound events using organized lists, tables, tree diagrams, and simulations
- 7.SP.8aUnderstand that, just as with simple events, the probability of a compound event is the fraction of outcomes in the sample space for which the compound event occurs
- 7.SP.8bRepresent sample spaces for compound events using methods such as organized lists, tables, and tree diagrams. For an event described in everyday language, e.g., "rolling double sixes," identify the outcomes in the sample space which compose the event
- 7.SP.8cDesign and use a simulation to generate frequencies for compound events
