My 6 year old did not enjoy Rosetta Stone. The speaking part was too difficult because the accent has to be perfect and she got frustrated. My then 8 year old had no problems. I personally found it confusing but taking it on faith and working through I did learn some vocabulary. We only stopped using it because we have a laptop shortage in this house. We can't do softmozart and Rosetta at the same time. Rosetta lost the draw. We are time poor. Try it out. If her accent is good she will have no trouble. Little reader French is a great place to begin as a way to get the accent and basics going before tackling Rosetta if she needs more time.
Have you read through the math threads on the forum? There are some really long ones. teach your toddler math is one of them and it covers a lot of ground.
In it we recomended many different things from books ( kitchen table mah, marshmallow math) to games (rightstartca rd games) to entire programs. Singapore and rightstart seemed to be the winners from this age bracket. Those of us that love Saxon don't usually start it until kids are ready for the 5/4 book. So around grade 3/4 math level for EL kids. You need something to use before then. You could use the early Saxon books if you wanted too but they seem to be a lot of work too me doing things in a lesson kids quite naturally learn through play. Their calender work is Genius though!
Yes there are Plenty of options.
try to pick something that is a complete curriculum with manipulatives and work through daily and systematically. Math is more easily learnt with regular practice.
At five years old I am not surprised she isn't interested in the dots at Shichida. I do believe they do help solidify quantity in older kids but she is unlikely to get subitisation from them. You will need more.
