I don’t know what is directly available to parent who home school, but our teachers have good results supplementing with ST MAth (k-8, very visual based), Zearn, and Freckle.
Zearn aligns really well with Eureka Math which is the old Engage NY.
This is the math curriculum that we use and love.
There are also a lot of free resources from the old EngageNY days if you Google.
(One of our schools recorded the largest increase in math scores in CA from 16-17 to 17-18. So we feel pretty confident in our choices.)
Also, a great teacher can be your best resource.
If you can afford it, an hour or two cash with a good special ed teacher per week might be worth the money.
