General Information Credits: N/A Length: Full Year

Weighted: N/A Format: Meets Daily

Prerequisite: N/A Grade: 7

I. Course Description The goal of this course is to develop an understanding of rational numbers and their operations and begin to apply that understanding to equations and inequalities in order to prepare for Algebra 1. These ideas will be integrated throughout the content strands of algebra, geometry, measurement, and data analysis and probability, with a focus on algebraic development. Students will also learn various problem solving strategies to solve appropriate applications within the strands listed above.



MARKING PERIOD: 1

Unit: Chapter 1 – Variables and Equations

Common Core Standards 7.NS.1.d. Apply properties of operations as strategies to add and subtract rational numbers.

7.EE.1. Apply properties of operations as strategies to add, subtract, factor, and expand linear

expressions with rational coefficients.

7.EE.2. Understand 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. For example, a + 0.05a =

1.05a means that “increase by 5%” is the same as “multiply by 1.05.”

7.EE.3. Solve multi-step real-life and mathematical problems posed with positive and negative

rational numbers in any form (whole numbers, fractions, and decimals), 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. For example: If a woman making $25 an hour gets a

10% raise, she will make an additional 1/10 of her salary an hour, or $2.50, for a new salary

of $27.50. If you want to place a towel bar 9 3/4 inches long in the center of a door that is 27

1/2 inches wide, you will need to place the bar about 9 inches from each edge; this estimate

can be used as a check on the exact computation.

7.EE.4.a. Solve 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?

7.EE.4.b. Solve 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.

MARKING PERIOD: 1 Unit: Chapter 2 – Integer Operations

Common Core Standards 7.NS.1.a. Describe situations in which opposite quantities combine to make 0. For example, a

hydrogen atom has 0 charge because its two constituents are oppositely charged.

7.NS.1.b. Understand p + q as the number located a distance |q| from p, in the positive or

negative direction depending on whether q is positive or negative. Show that a number and its

opposite have a sum of 0 (are additive inverses). Interpret sums of rational numbers by

describing real-world contexts.

7.NS.1.c. Understand subtraction of rational numbers as adding the additive inverse, p – q = p

+ (–q). Show that the distance between two rational numbers on the number line is the

absolute value of their difference, and apply this principle in real-world contexts.

7.NS.1.d. Apply properties of operations as strategies to add and subtract rational numbers.

7.NS.2.a. Understand 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 context.

7.NS.2.b. Understand 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. If p and q are integers,

then –(p/q) = (–p)/q = p/(–q). Interpret quotients of rational numbers by describing real world

contexts.

MARKING PERIOD: 4 Unit: Chapter 12 – Data Analysis and Probability

Common Core Standards 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.

7.SP.2. Use 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. For example, 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.

7.SP.3. Informally 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. For example, 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.

7.SP.4. Use measures of center and measures of variability for numerical data from random

samples to draw informal comparative inferences about two populations. For example, decide

whether the words in a chapter of a seventh-grade science book are generally longer than the

words in a chapter of a fourth-grade science book.

7.SP.5. Understand 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 1/2 indicates an event that

is neither unlikely nor likely, and a probability near 1 indicates a likely event.

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. For example, when rolling a number

cube 600 times, predict that a 3 or 6 would be rolled roughly 200 times, but probably not

exactly 200 times.

7.SP.7.a. Develop a uniform probability model by assigning equal probability to all outcomes,

and use the model to determine probabilities of events. For example, if a student is selected at

random from a class, find the probability that Jane will be selected and the probability that a

girl will be selected.

7.SP.7.b. Develop a probability model (which may not be uniform) by observing frequencies

in data generated from a chance process. For example, find the approximate probability that a

spinning penny will land heads up or that a tossed paper cup will land open-end down. Do the

outcomes for the spinning penny appear to be equally likely based on the observed

frequencies?

7.SP.8.a. Understand 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.8.b. Represent 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

Modified 6/20/2011 31


double sixes”), identify the outcomes in the sample space which compose the event.

7.SP.8.c. Design and use a simulation to generate frequencies for compound events. For

example, use random digits as a simulation tool to approximate the answer to the question: If

40% of donors have type A blood, what is the probability that it will take at least 4 donors to

find one with type A blood?

Student Objectives: In this chapter, students make-and-interpret stem and leaf plots, box-and-whisker plots, circle

graphs, and line graphs. Students decide which graph or plot is most appropriate for a data set.

Students use tree diagrams, the counting principle, permutations, and combinations to count

choices or possibilities. Students apply these counting methods to find the probability and odds

of simple events. Students also learn to distinguish between and find the probabilities of

independent and dependent events.
