## Order of Operations StAIR

This is a stand alone instructional resource created in PowerPoint and designed to teach students how to use the order of operations to simplify numerical and algebraic expressions. This lesson is intended for 8th or 9th grade Algebra 1 students, but could also be used with younger students to introduce order of operations or with older students to review the order of operations. Students should complete this lesson individually and at their own pace.

## Discussion for Order of Operations StAIR

3 years ago

### Serafina Chinappi (Teacher (K-12))

This was a well thought out lesson!  Topics were on target with both pre-algebra and algebra standards.  The structure of this lesson flowed very well, which would most certainly keep a young student's attention.  By keeping the slides very similar throughout, a consistency was provided to the students.  On examples, mathematical work was shown toward the left-hand side of the screen and mathematical reasons were shown on the right-hand side of the screen.  This consistent structure added to the flow of the lesson.

Technical Remarks:

I think it would be important to ensure that the fact that you must compute the multiplication and division, and addition and subtraction steps from left to right was highlighted.  This is a major misconception due to the fact that PEMDAS is often written horizontally rather than vertically.

The video of the PEMDAS rap was cute, but unfortunately very poor in audio quality.  I could barely make out the words the singers were saying.

You have created a nice tool for students to review a math principle that can be challenging.  I like how you used the mnemonic device technique to help students remember the order of operations.  The video is a nice touch for students who need to see and hear memory devices.  The only flaw I see is that your math equations are the same color as the background chalkboard which makes them impossible to see

Technical Remarks:

This looks like a great tool for students, but none of the math sequences would show up. It appears like their text is black and blends into the black of the chalkboard slide. (This appears to be a problem when viewing on a Mac). Please let me know when these are fixed - I know a couple of teachers in my building who would like using this!
