You just reminded me, back when she was in pre-k (age 4) she did do a workbook from Singapore Math called "70 Must Know Word Problems" which was level 1. She did those at the time with ease.
I will look for the one you mentioned. She definitely isn't entirely in love with math, but I think some of that may be due to her boredom in school this past year, especially in math. Reading instruction was much more tailored to her level. I did buy this book for her a few weeks ago and have yet to try it out

I do have an old 2nd grade EDM workbook from my older dd, do you think I should show my dd some of the stuff from that or just avoid EDM in general and stick to just problem solving?
