Yakko: Mom, I need you to enter this math assessment into the computer.
Me: Okay, but it isn't matching up with what it shows you were supposed to do today. Let's look at it.
Yakko: Well, it seems right to me.
Me: Okay, let's pull it up on the computer. (At this point, I notice that the assignment he did is half way through his workbook for the year.) Yakko, I don't think you did the right assignment. This is for unit 8. You're supposed to be in unit 3. This assessment is half way through the book!
Yakko: Huh!? I didn't notice!
By the way... he got 100% on the assessment.
