Great thread idea.

I registered DS3.5 for a trial of Dreambox two weeks ago after hearing good things about it here. He enjoyed the first round of an activity when it was novel, but he found it far too repetitive to enjoy it. It moves at about 10% of the pace it would, ideally. We won't be subscribing.

(As a contrast, DS does enjoy cherry picking problems out of the Singapore Math standards edition textbooks.)

What is to give light must endure burning.
