Algebra Tiles and Expressions

The video tutorial covers modeling equivalent expressions using algebra tiles. It explains how to represent variables and constants with tiles and demonstrates the equivalence of expressions using the distributive property. The tutorial also clarifies common misunderstandings and concludes with an introduction to the next lesson.
