I keep this at my guided reading table. Whenever we play "Bears in the Cave" I just do a quick check next to the numbers the students get correct. This helps me to know where the students are, but most importantly it helps me to quickly group students for math centers. I can have my higher students (the ones in the teens-twenties) quiz each other as a center. I can pull my lowest ones and work on them one on one.
There is one editable page for those of you who like to type in your student name
