The fourth grade math program deepens conceptual understanding, strengthens skills, encourages flexible thinking, and most importantly, excites children about the math everywhere! The Investigations curriculum, published by Pearson, stresses that the students reason about their mathematical ideas and communicate their ideas in a variety of ways. Avoca West fourth graders switch classes for math. During their math lessons, they follow a structure of Ten-Minute Math, hands-on activities, guided discussions, Math Workshops, and assessment activities.

Parents are encouraged to regularly use the Investigations Student Math Handbook with their children. The Student Math Handbook provides detailed examples of the concepts taught in class, definitions of math vocabulary, and directions for the recommended games. The Student Math Handbook is an invaluable resource for understanding homework assignments better and bridging the gap between home and school.
