I am considering both of these curriculums. I would like pros, cons, thoughts or opinions. I have a 1st grader right now and an up coming Kindergartener (he is kind of between grades ATM as he can read small words and seems very English inclined and his math skills are on target for pre k or maybe beginner k). My first grader is using Horizons Math. I like it ok but I want a more thorough curriculum. He doesn't really struggle wiht Math but it's boring for him. He doesn't want to do the work either. Like we're on double digit addition and he hates writing the problem so that he can find the answer. He hates finding the answer and if he has to give it some thought or use his fingers; he'd simply rather not do it.
Could maybe the curriculums be used together?
