I love the Kumon approach for improving calculation speed and for improving math confidence in really young kids. I recommend their books to use with your daughter at home. These are good for children as young as 18 months, as long as you don’t mind being more involved at that age.
With my eldest, I finished all of the basic-level Kumon Publishing books at home at a young age. It was a pre-YouTube era, so without TV, my eldest considered these books entertainment and enjoyed completing them.
With my youngest, we are doing cutting and starting with easy mazes now.
Kumon publising also has a smaller sized book for toddlers
For slightly older children, there are books on basic arithmetic and more.
