# Grade 12 Math Tutor

Twelfth grade math is a crucial year for students who intend applying for college or furthering their studies. A good math grade really improves your chances of getting in the best schools. If your student is struggling with this advanced math, then consider in-home tutoring now, rather than leaving it just before the SAT or ACT crunch.

Our one-on-one tutors work with the local curriculum. In the eleventh grade, students must master not only important mathematical concepts, but also the following academic skills:

- Problem solving.
- Reasoning skills to make mathematical conjectures, assess conjectures, and justify conclusions, and plan and construct organized mathematical arguments.
- Reflecting and monitoring their thinking to help clarify their understanding as they complete an investigation or solve a problem.
- Selecting tools and computational strategies to investigate mathematical ideas and to solve problems.
- Connecting: make connections among mathematical concepts and procedures, and relate mathematical ideas to situations or phenomena drawn from other contexts.
- Representing: create a variety of representations of mathematical ideas, connect and compare them, and select and apply the appropriate representations to solve problems.
- Communicate mathematical thinking orally, visually, and in writing, using mathematical vocabulary and a variety of appropriate representations, and observing mathematical conventions.
