## TASC Math Objectives

The 55-question TASC Math exam is broken into two sections. Section one is 50-55 minutes long and allows the use of a calculator; section two does not allow a calculator, but you have 55-60 minutes for this section. The test includes questions from five mathematical content areas: numbers and quantity, functions, algebra, geometry and statistics. Most of the questions are multiple-choice; however, there are a few gridded-response, constructed-response and technology-enhanced questions as well. The topics in this chapter may be encountered within the questions from multiple content areas. Test questions assess your ability to select and apply the correct math procedure to solve a problem as well as test your ability to judge the reasonableness of a solution.
