So first of all, I determined my groups with a quick pretest.
I have one group who needs to review multiplying multi-digit numbers by a one digit number, so they worked with my Title One aide for the first station (20 minutes) and then played multiplication war (just like the real WAR card game but each player turns over two cards and the highest product takes all - aces are worth one, jacks are worth 10, queens are worth 11, and kings are worth 12) for the second station (20 minutes). *You will need several decks of cards rubber banded together in a small basket (I suggest numbering each deck, for example putting number 1s on the back of one deck, numbers 2s on the back of a second deck, etc. so if a card is left on the ground - which we all know is inevitable - it can quickly be returned to the correct deck.)
My second group needs to review multiplying multi-digit numbers by a two-digit number, so they played multiplication war first (20 minutes) - (both groups are a bit below grade level so fact practice is a must) and worked with my Title One aide for the second station (20 minutes). I gave my Title One aide the practice sheets from www.themathworksheetsite.com to work on with both groups 1 and 2. Again, it took me five minutes to find the practice sheets and print them out. Further bonus, both groups got small group instruction which is beneficial for below level kids who struggle with attending.
During station number two I conferred with students playing multiplication war and The Factor Game. This is where/when I take notes/observe who's got it and who needs more practice. I just walk around with my fancy clipboard full of mailing labels and jot down notes. After class, I stick the notes into my conferring binder on each student's individual page. Couldn't be easier. At conferences, I'll just have to flip open to the student's page and share the notes with parents.
On Day 2 we continued the exact same stations, I just made each practice sheet one digit harder. Tomorrow is Day 3. Groups 1 and 2 will learn/play The Factor Game instead of multiplication war and group 3 will work on problem solving enrichment problems.
On Day 4 we will take a formative assessment so I can shift groups if needed for next week.
Gotta love math workshop - engagement, differentiation, small group instruction - all in one!
