This interactive manipulative allows students to explore algebraic expressions using virtual algebra tiles. Students drag variable tiles (x) and constant tiles (units) to model expressions, equations, and polynomials. The expression updates dynamically on screen. Supports TEKS Algebra standards and aligns with Common Core A-SSE (interpret structure of expressions).
Skills: algebraic reasoning, variable representation, expression building, concrete-to-abstract thinking. Multi-touch enabled for collaborative learning.
