Students need to sort the cards into 5 piles based on the number of solutions:
No Solution, All Real Numbers, Only 1 solution, All Real Number except 1 number, or 2 Solutions.
This sort has 2 levels (15 Cards in each):
** Basic: student can just look at the problem and decide (or attempt the formula and see what happens)
** Advanced: Student must rewrite the equation to isolate the absolute value before deciding.
