Fraction: How many equal parts there are in a whole.
Numerator: Represents the number of parts you have.
Denominator: Represents the total number of parts to make up 1.
The video also covers commonly represented fractions and introduces the idea that you can represent many different values as fractions.

Your students will then play Fish Lake to practice fractions.
Play Fish Lake
