Understanding Fractions with Pattern Blocks

The video tutorial demonstrates how to use pattern blocks to add fractions, specifically two-thirds and five-sixths. It explains the equivalence of different pattern blocks to fractions and shows how to combine them to find the sum. The sum is expressed in two forms: as a mixed number (one and a half) and as an improper fraction (three halves). The tutorial also clarifies the difference between mixed numbers and improper fractions, emphasizing that both forms are correct.

What is the value of a yellow pattern block in the video?

• One whole

• One-half

• One-third

• One-sixth
