Subtraction and Pattern Blocks Concepts

The video tutorial explains how to subtract mixed numbers using pattern blocks. It demonstrates representing two and one-third and one and five-sixth with pattern blocks, and the process of subtracting them by exchanging blocks to facilitate the operation. The tutorial concludes by finding the difference and simplifying it to one-half.

What is the initial problem we are trying to solve using pattern blocks?

• Dividing two mixed numbers

• Multiplying two mixed numbers

• Subtracting two mixed numbers

• Adding two mixed numbers
