Yes, I group my children for math instruction. I have found that the diversity in my class needs this type of instruction. I do have math as morning work on the board, and this is completed independently before we go into reading. After reading we do a whole group mini lesson and review the morning work. Then they rotate according to group. (Yes, they are grouped by ability - but I call them the Triangles, Squares, and Rectangles). One group is working on review items - such as math facts with a game (partner) or independent study, one group is with me focusing on the new skill, and the other group is with my TA doing the workbook or rapid facts. If my TA is not in the room with me, then the third group is working on their new skill. My math block is supposed to be 70 minutes, but we usually run over by 5 or 10 minutes. I try to work with my groups for 20 minutes. My children pay better attention this way.
I too use my interactive smart board during this time (for instance place value - roll the number cube and model the number). Make sure whatever you use for your math center has accountability with it. The children seem to enjoy grouping and it is much easier for me to keep track of what my students need.
