What mathematical area can be supported by using algebra tiles?

Using algebra tiles is particularly effective for supporting the understanding of estimation and solving equations. Algebra tiles are physical or visual representations of algebraic concepts, allowing students to manipulate and visualize numbers and variables in a tangible way. They can be used to demonstrate how to combine like terms, distribute across parenthesis, and isolate variables during the process of solving equations. This hands-on approach enables learners to engage with the material actively, making abstract concepts more concrete.

In addition to solving equations, algebra tiles provide a means to estimate values and understand how changing one part of an equation affects the others. This visual modeling of algebraic expressions helps students develop a deeper comprehension of equations and their solutions, particularly in preparing them for higher-level algebraic concepts.

Therefore, the correct answer recognizes the unique capability of algebra tiles to enhance understanding in estimation and the solving of equations.
