Understanding Whole Numbers as Fractions

Mia and her mom use baking to teach fractions. They start by cutting a cake into equal pieces, explaining denominators and numerators. As pieces are eaten, the fraction changes. They then explore how to represent more than one whole using fractions and demonstrate this on a number line. By the end, Mia and her mom have baked cakes and gained a better understanding of fractions.

What understanding do Mia and her mother gain about fractions and whole numbers by the end of their baking?
