Adding and Subtracting Fractions with Pattern Blocks

This video tutorial demonstrates how to model the addition and subtraction of fractions using pattern blocks. It covers the concept of fractions in everyday life, explains how to add and subtract fractions with common and different denominators, and illustrates the use of pattern blocks to visualize these operations. The video also explores equivalent fractions and provides examples to enhance understanding.
