Hello all:) I need some advice from those of you who use or have used MUS.
This has been our first year homeschooling, my youngest dd is 6 and would have been in first grade this year if in PS. She has just finished 1A in SM and has been doing the intensive problems book and word problems book along with it. She grasps the concepts very quickly and seems to be very mathmatically inclined (very unlike me and my older dd, but very much like dh:) She has most of her addition facts mastered now.
I am wanting to add in some MUS to spice things up a bit. So i have a few questions...What level should I start her in? What age is Primer usually used for? My oldest dd is 10 and would be in fourth grade this year but really struggles with math and forgets math facts very quickly. I had to start her in 2A this year to get her caught up and fill in many gaps. Some of it she already knew of plenty of it she didn't. She also has been doing the extra workbooks that my younger dd has been doing in SM. Where would you start her? TIA!
