Product Description

Activities, worksheets, guided notes and mastery tests to help your students become proficient at evaluating multi-step order of operations expressions (including exponents and brackets and braces) correctly! Apply PEMDAS correctly, make your goalposts as you evaluate numerical expressions, draw your “V” for “victory”, raise your hands in the air, and conquer order of operations once and for all! This complete unit contains a series of activities, including an exciting competition, that generate enthusiasm while teaching students to evaluate expressions (including exponents and brackets and braces) in the correct order. Order of Operations Inundation! works well in any late elementary or middle school math class. Note: per customer requests, this product has recently been updated to include an additional section which explores order of operations with brackets, braces, and fraction bars!. Specifically, this product now includes the following (detailed keys are provided for each activity):

Order of Operations Introduction Activity – Without any coaching, students are told to evaluate three different numerical expressions. Providing half the class with simple 10-key calculators that do not perform correct order of operations automatically is not necessary but will enhance the experience. During the classroom discussion that follows, students present their answers, only to realize that there are a variety of answers (the majority of which are incorrect, even those generated by calculators!), and that the need for a set of conventions regarding order of operations is a must. This activity builds enthusiasm for order of operations and sets the mood for the activities to come.

Order of Operations Guided Notes – Under the direction of the teacher, students discover the meaning and usage of PEMDAS and apply it order of operations expressions (exponents are not yet included). This activity introduces the “goalpost” method for evaluating expressions (draw a goalpost under the component of the expression you are evaluating, rewrite the remainder of the expression underneath the current one, continue to draw goalposts and rewrite the expression until you work to an answer, draw your “V” for “victory” around your work, and raise your hands up in the air in triumph!).

Order of Operations Worksheet - No Exponents – Students use what they have learned about order of operations to complete a worksheet full of a variety of order of operations expressions (exponents are not yet included).

Exponents/Powers Notes and Examples – Now that the students have a good feel for order of operations, they are introduced to exponents and how exponent and base work together to create a power. Exponents are then incorporated into order of operations expressions, which the students evaluate with teacher guidance (again cementing the use of the goalpost method).

Order of Operations Worksheet – With Exponents – Students now attack a series of order of operations expressions, with exponents included, that increase in difficulty and take up to five steps to evaluate.

“Two-Three” Order of Operations Challenge – This exciting game allows students to put their order of operations skills to the test in a challenging competition. Students are asked to “create” as many numbers as they can using a total of four two’s and three’s (for example: 2 + 2 + 3 • 3 = 13) and the correct order of operations to evaluate them.

Order of Operations Mastery Tests – To ensure students have completely mastered the basics of order of operations, five of these tests are provided to test and retest students until they pass with a perfect score. There are simply two questions on each mastery test, but each of the tests comprehensively covers all operations and rules within PEMDAS.

Order of Operations Notes – Other Grouping Symbols – In this RECENTLY-ADDED section, students are introduced to brackets, braces, and fraction bars as grouping symbols. They are guided through the process of using GEMDAS (“G” meaning “grouping symbols”) instead of PEMDAS to evaluate these expressions, and “working their way out” when handling multiple grouping symbols. The goalpost method remains at the core of the GEMDAS process as the teacher guides the students through these more complex concepts and problems.

Order of Operations Worksheet – Other Grouping Symbols – In this RECENTLY-ADDED section, students now use GEMDAS to attack a series of order of operations expressions involving brackets, braces, and fraction bars. The numerical expressions on this three-page worksheet increase in difficulty and take up to eight steps to evaluate.

Good luck in your use of Order of Operations Inundation!
