Here is an international math competition for the younger grades.
Students from 1st to 12th grade can compete in Math Kangaroo. The competition is held annually in March.
To sign up, first look for a local center, in case there is one nearby. If there is one nearby, contact them and let them know that you are interested.
If there is no local center nearby, try to get permission from your daughter’s school to register a center there.
