When I'm working with a small group for literacy the rest of the class is doing workshop. Our district is currently using the Imagine It! curriculum which is the new Open Court. For differentiating instruction the curriculum asks that you add workshop to your literacy schedule. My workshop usually lasts about 40 minutes which means I can always see at least two to three groups in one session. Workshop is similar to centers except the students receive differentiated activities that are at their specific level working on specific targets. For example, today's workshop will run like this:
9:15 -- students get with their DRA level group (there are four homogenous groups)
with their groups, students work on a "Must Do" at a specific location in the classroom (either computers/listening center, library, carpet, back table, or the teacher's desk). Students know their Must Do is something that they must do in order to choose a "May Do". For 20 minutes students work on their target. Their target might be sight word practice, reading just right books, working on consonant blends, compound words, handwriting, paragraph writing, etc. They work on their same target in a different way every day. This way the student doesn't get board of working on their target skill. The students work in their small groups while I pull a small group at my desk to do guided instruction.
9:35 -- the timer goes off and students can choose a "May Do". I have a list of literacy games on a small board that students can refer to and they may do any of those activities (read the room, put word cards in ABC order, copy word wall words, write on the white boards, library, buddy read, or play a file folder game). I change up the May Do's every month as well to keep it interesting. The students know they will have until recess (10:00) to do their May Do's and they know they must choose wisely or I will choose for them. During this time I can usually pull at least two more reading groups. The students can work independently, with a partner or in a small group during this time. I always have students review the rules of workshop before we begin: 1. work, 2. whisper, 3. share, 4. please don't interrupt. If I see a student breaking one of the rules I follow the WBT guidelines and simply call out,"class" (yes) "what is rule number 4 of workshop?" (Rule #4: Please don't interrupt.) "thank you". The student who was trying to interrupt the reading group quietly walks back to try to solve the problem on his/her own.
This system has worked really well for me. I was hesitant at first to switch from centers to workshop because you have far less control, but the students LOVE workshop and I can often use our WBT Scoreboard as an incentive to earn more/less workshop time.
I hope this helps,
