Understanding Fraction Subtraction with Pattern Blocks

The video tutorial explains how to subtract fractions using pattern blocks. It defines the value of each block and demonstrates how to perform exchanges to find equivalent fractions. The tutorial shows the subtraction process by removing pattern blocks and calculating the difference. An alternative method is also presented to illustrate the subtraction of fractions.
