Figure Me Out! “Order of Operations” By: Carrie Bradley, Sheri Harris, and Cindy Davis
Core Content MA-06-1.3.1 Students will add, subtract, multiply and divide whole numbers, fractions and decimals to solve real-world problems and apply order of operations to simplify numerical expressions. DOK 2
Program of Studies MA-06-1.3.2 Students will explain how operations (addition and subtraction; multiplication and division) are inversely related.
Review “PEMDAS” P-Parentheses E-Exponents M-Multiplication D-Division A-Addition S-Subtraction
Game Explanation • Each group will need to choose 3 number cards and then at least 3 order of operation cards. • Each group will need to work together to write and create using their chosen options an order of operations problem. • Each group will then need to work together to solve their created problem. • After all groups have completed this task the class will come together for a class activity.
Game Explanation Continued… • Each group will take turns in coming up as a group, write only the answer on the board, select the cards that match the numbers and order of operations they chose, then stand with them in a random order. • The rest of the class will then work together to figure out the correct order of the numbers and order of operations to derive the group’s answer on the board. • One person from each group will raise their hand to answer each group’s posed problem, until all groups have presented their order of operation problems.
Example The number 32 is written on the board. The group would select: 5, 6, 2, x, + In random order hold them up. Then class solves to get:
