I have been using both Horizons and Singapore math with my 8yo (almost 9yo) DD. She is ready to begin Horizons Grade 4 and is part way through Singapore 3B. I feel that using both of these programs has given her a really great math education so far. However, the trouble is that I have three younger DCs, two whom I also teach and one toddler. I am swamped! Math takes so much of our time and I would love to simplify, but I don't know which program to drop. My DD LOVES Horizons and would be so disappointed to drop it. However, I am afraid to let Singapore go because of the strong mental math//critical thinking/word problem component. I have even learned a lot from teaching Singapore! In an ideal world, I would continue with both, but if I do that I'm afraid I will be so frustrated that no one will be happy. :crying: My DD is bright and learns new things very quickly so I want to make sure that she is challenged and stretched. I have thought about using just Singapore's CWP and Mental Math books as a supplement to Horizons, but I wonder what we'll be missing if we don't actually use the text, workbook, and HIG. I've even thought about moving to Teaching Textbooks as that would free me up so much, but I've read mixed reviews on TT and I don't want to compromise the quality of her education. Help! What would you do?
