We've been working on Order of Operations this week and my students have the Order part down, but it is the Operation part they need some help with.
I did an activity where I asked students to purposely make a mistake when evaluating the expression. Then the class had to find their mistake.
My students LOVED this. It went over so well and they all wanted to go up several times to try to stump their classmates with the tiny little error they made.
Eventually, I found 3 students who had evaluated the expressions in 3 different ways and then had the class explain their mistakes.
They made mistakes with the exponents, solving in the wrong order, ignoring grouping, not regrouping when adding and subtracting, etc. It shows that they know what type of errors are common and will hopefully be on the look out for it.
I have a station that I will pull out next week where the students will get an expression solved two different ways and will have to sort them into correct and incorrect. That station is available in my store. If you have it, make sure to re-download it because I made some updates to it.
