After pulling my second grade dd from public school I started using LOF and Rays. We just started at the beginning of both and we alternate. Monday Wednesday is LOF Tuesday Thursday is Ray’s. Friday is Xtramath. Everyday she also does an online math game. With LOF she writes out everything, with Ray’s I make a worksheet in Startwrite with the problems for the days lesson. On the longer review lessons in Ray’s we only do even problems. Next year I will start Ray’s with ny Ker but she will only be doing the problem with manipulatives and not writing it out. This is what seems to work best for us.
