Algebra 1
Order of Operations
Content Standards:
1.0, 1.1 - Students identify and use the arithmetic properties of real numbers.
2.0 - Students understand and use the properties of taking the opposite and the reciprocal.
10.0 - Students add, subtract, and multiply monomials.
Review PEMDAS and present a few worked out problems to students. Students will read and analyze incorrect simplifications of expressions. They will demonstrate that although simplified incorrectly, there may be some correct steps in the process. They will discover the errors and explain the incorrect use of Order of Operations.
Strategically groups students.
Special Needs
Have students name and act out activities that work only when done in the correct order. such as putting on socks. shoes. and tying laces. Point out the parallel to the agreed-upon order of operations in mathematics.
Below Level Students
Remind students to write out all intermediate steps when simplifying and evaluating expressions. This will help them gain a better understanding and prevent errors.
Advanced Students
Challenge students to add grouping symbols in the correct places to make the following expression true (and others like it): 34x6"3 :2"2 x3"2- I = I70
EL Students
Suggest that students may find it helpful to think of the hue as carrying the exponent on its shoulder so that together they make up a power. Make sure students say “2 to the 4'“) and don't skip over those important little words!
Performance Assessment:
Informal: active listening. spot checks, play math games (if time). project
Formal: Assign problems in textbook strategically. Let students complete whichever 12 problems they wish. They can attempt more problems if they want, but need to get 12 correct for a perfect score.
Also: notes summary, quizzes, Unit test
Alternative Assessment: Have students choose numbers to substitute for x and y in
6xy"2 + 3(xy)"2 and evaluate the expression. Ask students to explain each step in their
calculations.
Assess: Checkpoint Quiz
