This product contains 18 weeks of 4th grade math that is based on Common Core curriculum. It was designed to incorporate a significant amount of the curriculum and to help transition and scaffold the skills needed to master 4th grade math. The next 18 weeks will be available in a timely manner and will be more heavily based on the standards related to fractions. You can use this product as morning work, daily work, homework, station work, as remedial work for 5th grade students or advanced work for 3rd grade students. If you are using it as advanced work at the end of the year you can save a little if you just buy the first quarter. I hope that this benefits your students!
