(Palm Coast, FL)
I was surprised at the previous review because after using this with my daughters for 2nd grade, I found just the opposite.
The only “required” work is the student workbook, all the other things in the teacher guide and the worksheets are all optional.
This gives you the flexibility to do more review when you need it and very little when you don’t. It is much less repetitive than a mathematics curriculum like Saxon and my kids always liked it much better!
