Expression Escape Room

Grade 7Math1 days

The 'Expression Escape Room' project for 7th-grade math students involves using properties of operations to add, subtract, and simplify linear expressions in a virtual escape room setting. Students tackle a series of puzzles with increasing complexity, revolving around expressions with integer, fractional, mixed, and multiple variable coefficients. Through collaborative problem-solving and application of mathematical strategies, students aim to crack codes and successfully 'escape' each level, deepening their understanding of linear expressions and their manipulations. The project's alignment with Common Core Standard 7.EE.A.1 ensures students achieve key learning goals, such as handling different forms of linear expressions and enhancing problem-solving skills.
