During this easy to implement, classroom tested, fun unit students use logic and multiple representations (words, drawings and symbols) to evaluate mathematical expressions.
The unit concludes with students articulating the order of operations rules. The unit includes lesson description (12 pages), student pages (25 pages) and answer key (25 pages).
I have presented this unit at national, state and regional conferences and teachers love it!
