### MTEL Math: Number Theory Chapter Objectives

The Massachusetts Tests for Educator Licensure (MTEL) exams test the preparedness for future educators to teach in pre-kindergarten through 12th grade classrooms. The MTEL Mathematics test is designed to test a future educator's readiness to teach mathematics or related courses.

This chapter, Number Theory, will be most applicable to the exam's Number Sense and Operations subarea and will be especially useful for questions dealing with principles of number theory. The Number Sense and Operations subarea accounts for 12% of the exam's score weight and is one of the six testing areas found on the MTEL Mathematics test.

The test consists of multiple-choice questions and open-response assignments and takes roughly 4 hours and 15 minutes to complete.
