Our Order of Operations Lesson Plan demonstrates how to simplify and solve problems by identifying and using the order of operations correctly. Capitalize on peer learning as students create their own order of operations equations for another student to solve, which strengthens the ability to identify inaccuracies. Reinforce the order of operations by challenging students to create their own pneumonic.
Sample Classroom Procedure / Teacher Instruction
- Display the following problem solved two different ways: 3 + 7 x 2 = 20 & 3 + 7 x 2 = 17. Ask students how and why the answers are different.
- Allow for responses and discussion. Introduce the order of operations by explaining the difference in the two answers. Show a few more examples.
- Distribute Order of Operations content pages. Read and review the information with the students. Use the additional resources to enhance understanding.
- Distribute Activity page. Read and review the instructions. Each student will create a set of problems for another student to solve. The students should use other paper to create an answer sheet. Give students sufficient time to complete. Answers may be fractions. (Note: Some problems may involve negative numbers. Depending on class level, you may tell students not to use negative integers or allow the answers to be negative.)
- Once completed, students will exchange the sheets. Give sufficient time to solve. Students will then return completed sheets to the original student who created the page for correction. Once all are checked and reviewed, explain to students that everyone had the same digits on the page, but there can be many different answers depending on the signs used and the order of operations. Distribute Practice page. Check and review the students’ responses.
- Distribute the Homework page. The next day, check and review the students’ responses.
- In closing, display the following challenging problem for students to solve: 3 + 72 – (6 + 2) + (32 x 2 + 7) + 8 – 10 ÷ 5 + 9 x 2
- Tell students to take their time. Give a small prize to those who solve it correctly. The answer is 93.
- Ask students if they can think of a new pneumonic for remembering the order of operations.
- Allow for responses and discussion.
