Our general recommendation is the Saxon Math K to 3 program which is a manipulative based, hands-on program. They feature short incremental lessons that slowly build over time and continual review of previously learned concepts.
While we have video lessons for all other Saxon Math titles, we have not created DIVE lessons for Saxon K-3 or for other lower grade levels nor do we sell the K-3 books. However, the Saxon Math K-3 books can be purchased at Rainbow Resources.
Another option is Horizons Math. It is a solid math curriculum. We have had many students successfully transition into DIVE/Saxon Math 5/4 Third Edition.
