All California public school students must satisfy the California High School Exit Examination (CAHSEE) requirement, as well as all other state and local requirements, in order to receive a high school diploma The CAHSEE is divided into two parts: English-language arts and mathematics All questions on the

CAHSEE are evaluated by committees of content experts, including California educators, teachers, and administrators, to ensure the questions’ appropriateness for measuring the designated California academic content standards in English-language arts and mathematics In addition to content, all items are reviewed and approved to ensure their adherence to the principles of fairness and to ensure no bias exists with

respect to characteristics such as gender, ethnicity, and language

This document combines released test questions that have appeared on the mathematics part of the

CAHSEE since the 2000–2001 school year, and contains new test questions from the 2007–2008 school year A similar document for English-language arts is also available The questions are grouped by strand (e.g., Number Sense) At the beginning of each strand section is a list of the specific standards assessed on the CAHSEE Following a group of questions is a table that gives the correct answer for each question, the content standard each question is measuring, and the year each question originally appeared on the

CAHSEE

The following table lists each strand, the number of items that appear on the exam, and the number of released test questions that appear in this document

The following ten California mathematics academic content standards from the Number Sense strand are assessed on the CAHSEE by 14 test questions and are represented in this booklet by 38 released test questions These questions represent only a few of the ways in which these standards may be assessed on the CAHSEE

GRADE 7 — NUMBER SENSE Standard Set 1.0 Students know the properties of, and compute with, rational numbers

expressed in a variety of forms:

and negative powers of 10) with approximate numbers using scientific notation.

terminating decimals) and take positive rational numbers to whole-number powers

in estimations, computations, and applications.

and compute simple and compound interest

Standard Set 2.0 Students use exponents, powers, and roots, and use exponents in

working with fractions:

expressions involving exponents with a common base

root of a perfect square integer; for an integer that is not square, determine without a calculator the two integers between which its square root lies and explain why.

absolute value as the distance of the number from zero on a number line;

and determine the absolute value of real numbers.

by 30 released test questions These questions represent only a few of the ways in which these standards may be assessed on the CAHSEE

GRADE 6 — STATISTICS, DATA ANALYSIS, AND PROBABILITY Standard Set 1.0 Students compute and analyze statistical measurements for data sets:

Standard Set 2.0 Students use data samples of a population and describe the

characteristics and limitations of the samples:

validity of the claims

Standard Set 3.0 Students determine theoretical and experimental probabilities and use

these to make predictions about events:

(e.g., tables, grids, tree diagrams) and express the theoretical probability of each outcome.

and percentages between 0 and 100 and verify that the probabilities

computed are reasonable; know that if P is the probability of an event, 1 - P

is the probability of an event not occurring

GRADE 7 — STATISTICS, DATA ANALYSIS, AND PROBABILITY Standard Set 1.0 Students collect, organize, and represent data sets that have one or

more variables and identify relationships among variables within a data set by hand and through the use of an electronic spreadsheet software program:

or box-and- whisker plot; use the forms to display a single set of data or to compare two sets of data.*

how the data points are distributed and any apparent relationship that exists between the two variables (e.g., between time spent on homework and grade level)

* The crossed-out portion of this standard is not assessed on the CAHSEE, but is still included in

grade-level standards.

Question Number Correct Answer Standard School Year of Exam

The following ten California mathematics academic content standards from the Algebra and Functions strand are assessed on the CAHSEE by 17 test questions and are represented in this booklet by 40 released test

questions These questions represent only a few of the ways in which these standards may be assessed on the CAHSEE

GRADE 7 — ALGEBRA AND FUNCTIONS Standard Set 1.0 Students express quantitative relationships by using algebraic

terminology, expressions, equations, inequalities, and graphs:

equation, an inequality, or a system of equations or inequalities that represents a verbal description (e.g., three less than a number, half as large

as area A)

as 3(2x + 5)2

of a specific part of a graph in the situation represented by the graph

Standard Set 2.0 Students interpret and evaluate expressions involving integer powers

and simple roots:

negative whole-number powers as repeated division or multiplication by the multiplicative inverse Simplify and evaluate expressions that include exponents

extracting roots to monomials when the latter results in a monomial with an integer exponent.

Standard Set 3.0 Students graph and interpret linear and some nonlinear functions:

per unit of horizontal change (change in x-value) is always the same and

know that the ratio (“rise over run”) is called the slope of a graph.

the number of an item, feet to inches, circumference to diameter of a circle)

Fit a line to the plot and understand that the slope of the line equals the quantities.

Standard Set 4.0 Students solve simple linear equations and inequalities over the

rational numbers:

rational numbers, interpret the solution or solutions in the context from which they arose, and verify the reasonableness of the results.

represents the statement, “A number, x,

decreased by 13 is less than or equal
