TAKS MATHEMATICS The seventh-grade mathematics TAKS Objectives and TEKS Student Expectations (SE) describe what students should know and be able to do in this grade. However, teachers need to have complete understanding of the TEKS Student Expectations (SE) content that will be tested. Understanding the curriculum content what comes before and after seventh grade will enable them to assist students in learning the required mathematics knowledge and skills more effectively. It is important that students develop conceptual understanding by engaging in activities that require the use of manipulatives. TAKS Objective 1 At seventh grade, students should be able to
sequence numbers or the words associated with numbers;
work with problems that include information expressed as numbers or ranges of numbers; and
round numbers before performing any computations when estimating. The use of compatible numbers (numbers that are easy to compute mentally) may be helpful.
TAKS Objective 2 At seventh grade, students should be able to write an expression to find the nth term where n represents the position of the term in the sequence; and identify the expression when given terms in a sequence, and vice versa. match a relationship represented by an equation or written description with the same relationship shown in pairs of numbers.
TAKS Objective 3 At seventh grade, students should be able to
use geometric models shown individually or as part of a more-complex figure (for example, supplementary angles may be shown as part of a parallelogram); and
graph points on coordinate grids using all four quadrants.
TAKS Objective 4 At seventh grade, students should be able to
iv
utilize the conversions and formulas on the Mathematics Chart to solve problems;
measure with the ruler on the Mathematics Chart only if the item specifically instructs students to use the ruler;
use the given dimensions of a figure to solve problems; and
recognize abbreviations of measurement units.
TAKS Objective 5 At seventh grade, students should be able to
match a situation with a sample space that lists all possible combinations or select the missing portion of a given sample space;
determine whether the graphical representation of the given data is appropriate and/or accurate.
distinguish among mean, median, mode, and/or range to determine which is most appropriate for a particular purpose
match the mean, median, mode, and or/range with a given data set, which may be listed in the text of the item or presented in a graphical representation; and
Identify the missing piece of data that will produce a target mean, median, mode, and/or range for a data set.
TAKS Objective 6 At seventh grade, students should be able to
select the description of a mathematical situation when provided with a written or pictorial prompt;
identify the information that is needed to solve a problem;
select or describe the next step or a missing step in a problem-solving situation;
match informal language to mathematical language or symbols;
identify the question that is being asked or answered;
draw a conclusion by investigating patterns and/or sets of examples and nonexamples. A nonexample, or counterexample, proves a general statement to be false;
understand that nonsensical words may be used to label sets of examples and/or nonexamples; and
choose the correct supporting information for a given conclusion.
v MATHEMATICS CHART
For seventh grade the Mathematics Chart will have measurement conversions on the front and formulas on the back.
A metric ruler and a customary ruler will be provided on the front of the separate Mathematics Chart.
Items that require students to measure with a ruler from the Mathematics Chart may be found in any objective as appropriate.
TEST FORMAT
The seventh grade test includes a test booklet and a separate machine-scorable answer document. Enough room is left around each item in the booklet for students to work each problem. However, student responses must be recorded on the separate answer document. Any item may include application context and extraneous information. Most items will be in a multiple-choice format with four answer choices. Not here or a variation of this phrase may be used as the fourth answer choice when appropriate. There will be a limited number of open-ended griddable items. For these items a seven-column grid (with one column designated as a fixed decimal point) will be provided on the answer document for students to record and bubble in their answers. Digits must be in the correct column(s) with respect to the fixed decimal point. This griddable format is intended to allow students to work a problem and determine the correct answer without being influenced by answer choices. An example of a blank grid is shown below.

Test Taking Tips 1. The students may write in this review booklet. Encourage students to highlight the important information and sketch out the problems in order to visualize and to change an abstract concept into a concrete concept. 2. Rewrite the problem to make it understandable. 3. Teach students to mark through extra information and circle the information needed to solve the problem. 4. Let the students develop their own strategies and encourage them to share with the other students. 5. The students may work the problems before looking at the answer choices, and then match their answers to the answer choices. 6. Cross out the impossible answers. 7. Require the students to read their answers back into the problems to see if the answer is reasonable.
