Does your student slump or stride into math class? My hope is that each of my math students steps confidently into any algebra, geometry, pre-calculus, calculus, or middle school math classroom.

### Build Confidence In Math With Prerequisites

Last week, I was reviewing probability with an ACT Math student. When I realized that she struggled to determine where each number should go in her calculation, I pulled out a classic middle school-level textbook to reteach probability’s prerequisites: outcomes, events, and relative frequency. As she masters these fundamentals, she’ll learn the “why” behind the “how” of probability. When she returns to the ACT prep book, she’ll be more sure of herself when she meets a probability question.
