Discussion for Order of Operations StAIR
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.
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.

The sound effects are great. It gave me a real sense of accomplishment! Have you thought about adding a voice for the text portion? If you have a student that struggles with reading, but is pretty good with math, he/she may still have a lot of trouble getting through this. I like how you show everything step by step. All of the videos work well, which is great. I could not manage to make the videos functional on my own StAIR. Maybe I will have to publish them in YouTube and link them. The videos are a nice touch. I think the students will find them engaging and memmorable. In the first example, the students are asked who does the problem correctly. I know that I really wanted a chance to figure it out, but the answer was just given. Could the student have a chance to answer? It also might be worthwhile to point out why the other options were not correct. Giving the students options for extra examples is a great idea. I was ready to move on, but students may not be. On the first challenge, there are suddenly brackets. Have you already discussed brackets at this point? If not, have you thought about holding off for one or two problems until they get the hang of it and then throwing them a curve ball? If not that is fine. You explain it well. It might just freak some students out a bit. On the slide that says "Evaluate 21-x+2(times) 5 for x+7, the texts adds really fast. I kind of felt like I didn't have time to think. Have you considered slowing it down at all or having the text prompted by clicking? That way students could move at their own pace. This whole thing is really great! I enjoyed doing math again! The website was really great, too! I missed the $100,00 question, though. Good thing I am not a math teacher!

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
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!

This is an excellent resource for teachers and students. Try it out.
