Some things I've noticed already vs. Singapore:
- parental involvement
Time seems to be less right now. Teaching and Meeting book don't really take long, and the workbook pages are so well covered before they are assigned that it's not difficult for the child to finish. We're doing both pages in one sitting, all the problems.
Review. This is one of the biggest reasons we switched and something I am really happy with. Something is introduced and then constantly revisited and refreshed. Sweet Pea was really frustrated with Singapore that topics would come up, she'd learn them, and then we'd leave them. I was spending a lot of time (and ink) finding or making review sheets for her. I didn't like that- I want a curriculum that has it all together for me.
Manipulatives- I really like all the hands on parts of Saxon. It's not all manipulative work like Miquon (which we tried and failed with) but it's not all book work, either. Singapore did have suggestions for hands on stuff, but as the parent you had to locate materials and plan it out and that can be really hard to do.
Level. I did not take Ewe's advice and go a level up. I should have. Sweet Pea finished Singapore 2a and 2B and I put her in Saxon 2. It's all really easy for her but it is building her confidence up so we'll just go through at a quicker place and move into Saxon 3 by fall. Singapore does seem more advanced then Saxon, but Saxon seems far more thorough. It kind of felt like Singapore was advancing at the cost of mastery.
