Students practice simplifying multi-step algebraic expressions by ordering the correct sequence of steps. Learners drag each step into place, reinforcing the order of operations as they work through progressively complex expressions. This activity supports TEKS 5.4.E (simplify expressions) and aligns with Common Core 6.EE.A.2.
Skills: order of operations, algebraic reasoning, sequencing, expression simplification. Grades 4-8.
