Here is a small strategy I used for our review day today.
In Advanced Functions we were reviewing average rates of change and instantaneous rates of change.
Instead of just doing problems from the book I organized the rate problems in 4 sets, polynomial, rational, trigonometric, and exponential/logarithmic functions. Each set had 3 problems.
I organized the class in groups of 3 and gave each group a set. They were to complete the problems and check the answers.
The kicker here was that the sum of the 3 answers in a set was written on the board.
If the group got all questions correct their sum of their answers would match correctly. But…… If one was wrong they had to check all solutions and decide which needed fixing.
First, this small change made all groups work more carefully than usual. And second, when they had to double back, you could see them rationalizing which answers “had” to be correct and which answers were “toss ups”.
It was a great tool for students to self assess and evaluate their own readiness.
After each group completed a set they would swap with another group… Eventually completing all sets.

I realize this is a bit off-point, but I’m loving those desks! Did you put a special coating on them so they would erase easily?
Thanks. No special coating! They came like that. It was an added bonus when we found out they can be written on with dry erase markers. I believe they are called boomerang desks.
