The content is not so complex at these early levels and is pretty easily blended. If this is not possible, perhaps you could change students with another teacher where you, for example, teach all the second graders social studies and your partner teaches all the third. If you have just a few of one grade level, often another teacher will just take them and teach them with her class. This is what most teachers of combination grades do. I personally believe this multi-age can be a benefit.
Parents often are unhappy.
The 3rd grade parents will think their kid will be held back. You have to do a good job of exlaining the program. There are many plusses and you have to delineate them carefully to parents. They have been told negative things about combos so come in with a negative attitude.
