Understanding Fractions with Pattern Blocks

This video tutorial teaches how to subtract fractions using pattern blocks. It begins by defining the value of each pattern block and demonstrates subtraction through three examples: subtracting one red from one yellow, one blue from one red, and seven blue from five yellow. The tutorial uses online pattern blocks to visually represent these operations and explains the process of exchanging blocks to achieve subtraction. Each example is also expressed in fractional terms, highlighting the importance of common denominators.
