Figuring out how to many centers can be a challenge. I have found that simpler is better. My go-to plan is called CAT Centers. This is a set of 3 basic centers that work for reading or math. CAT stands for Computers, All by Yourself, and Teacher Table.
Computers are when your students work on technology. This is the easiest center. You make devices available and let your students know what programs they can use.
All by Yourself is for any type of independent work. This can be a single activity or a selection of tasks students need to work on. You can keep several baskets out with the work they need to do during their All By Yourself time and change them weekly or as needed.
Teacher Table is for small group instruction. Most teachers already do guided reading, but guided math is awesome too! CAT centers are the perfect way to implement math workshop with guided math.
This resource includes posters for using the CAT system in your classroom. There are headings and expectations posters for each center.
