Keep your children busy and entertained during lock-down, and do so while preparing them to live and work in the global economy.
Let them learn Spanish on-line with native speakers, and do so at a very affordable price. If your child has begun to learn Spanish in school and needs to practice during the lock-down, rather than permit skills to atrophy, or if your child has yet to begin, there is nothing so effective as working with a native speaker on a one to one basis.
The best time to learn a language is when you are young. The next best time is now.
