Atomic dating game answer sheet
Because as soon as I start reteaching something that they have heard before, their minds shut down and start ignoring me. They think that a negative exponent means that you need to change the fraction to its reciprocal to make the exponents positive. And, don't even get me started on the order of operations.
I guess they are thinking, "I don't have to listen. No matter how many times I say that multiplication and division must be performed from left to right, I have a student who will argue with me that multiplication comes before division in PEMDAS so we must always do it first.
I probably ended up spending two weeks on exponent rules, and I still had a group of students who just didn't get it. Day 1 - We played a game that I found on Nathan Kraft's blog.
For negative exponents, I use "cross the line and change the sign of the exponent." We didn't have time to explore why this works, but I will cover it more in depth with my students when they reach Algebra 2.
We also discussed why anything raised to the zero power is equal to 1.
I think having students write out the learning goal will be beneficial because it will force them to focus on what the quiz was trying to accomplish in the first place.
When students turn in their error analysis sheet and get approved to reassess that skill, they will have to write out the learning goal AGAIN on their retake sheet.
