Thank you so much everyone.... I was looking at MCT but it seems like a lot of pieces especially considering that I will be using it for a 2nd and 3rd grader plis I have a rising 1st grader. And 9 month old twins. Is this an accurate assessment? I'm looking for something quick and efficient. I have been looking at easy grammmar, FLL and gwg. Or anything else that will fit my situation. Any thoughts considering my situation. Anyone used these long term with good results? Thank you.
