This shld be a separate thread but, CollinsMum, how do u guys find alcumus? My son's math is all over the shop. He loves algebra (Ed zacarro), but I've asked for him to set that aside for awhile because he has huge gaps in elementary math, which Aleks seems to have patched. He finds it a total bore though and wants to jump back into Ed zacarro. We've recently found some puzzles and I was hoping to stay at this level (grade 4,5,6-ish) to play around. Any thoughts here will be appreciated!
I'll do a new thread in Recommended Resources...
