The Math Group Rotations using the acronym TIMES has been designed based on best practices in Elementary Math.
Within the TpT product, you will find a letter describing the most successful way to run the rotations. There are also posters for each rotation/group that may be hung or used on the white board when describing the task.
I have personally seen much success with Math TIMES, including in a class of 34 students with 9 IEPS.
Enjoy! Please leave me Feedback! I would love to hear how you are using them!
