The video tutorial demonstrates how to add mixed numbers using pattern blocks. It begins by defining the values of different pattern blocks and then uses them to represent the mixed numbers one and one-half and two and five-sixths. The tutorial shows how to combine these blocks and perform exchanges to find the sum, which is expressed as both a mixed number and an improper fraction. The video concludes by explaining the difference between mixed and improper fractions and confirming that both representations are correct.

What is the main objective of the lesson involving pattern blocks?

• To find the difference between mixed numbers

• To find the sum of mixed numbers

• To multiply mixed numbers

• To divide mixed numbers
