Hi thanks,

I like 'mathletics' but neither this or Aleks says anything about other languages.

Apparently mathletics will have rainforestmaths for free.

I think I will talk to the teacher to see what she thinks anyway.

There is as well some kind of consultant that provides enrichment packages for gifted kids in elementary schools. The person in charge is the mom of three HG+ children, so she obviously has some first-hand experience.
Would you hire this kind of services? I think their bill will easily go up to 500 euros, so they are not exactly cheap.
