### Math TAKS

### Objectives and Sub-objectives

Grade 6th, 7th, and 8th

Test Format

- The 6th. 7th, and 8th grade tests include 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.

TAKS Math Prep.

Test Format

- 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.

Mathematics Chart

- The Mathematics Chart includes 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.

Objective 6 Problem Solving Plan

- Understand the problemOrganize the information you are given and identify exactly what you must find. You may need information that is not given in the problem, such as a formula. You may be given information that is not needed in order to solve the problem.
- Make a planAfter you have organized the information, decide how to use this information to find an answer. Think about the math concepts that apply to the situation. Identify the order in which you will find new information and the formulas or equations you will use to find it.
- Carry out the planAfter you have chosen a problem-solving strategy, use the strategy to work toward a solution to the problem. Go step-by-step through your plan, writing down important information at each step.
- Check to see whether your answer is reasonableCheck to see whether your answer makes sense. Does it answer the question asked? Is it stated in the correct units? Is it reasonable? You can estimate the solution and then compare the estimate to your answer. They should be approximately equal.
