My end of the year first graders right now are buzzing through their centers as fast as they can which causes some behaviors (ummm I mean a lot). I need to really watch and analyze which centers are they flying through. Next year in second grade I'll probably do centers again to have enough time for reading groups. What are some "meaty" center ideas that will keep this kids working and engaged? Some of my center the kids just get TIRED of after we have them for more than like a month. They are good centers - but if I change it up the behavior gets better. But I don't have time to be changing centers all the time - I'm already spending time copying new minibooks for them to make, poems for their poetry binders, and others. I think I'm going to start a science/social studies center because there is just not enough time in the day for some of it.
