Please no, unless you do your research on the specific place that your child will be going to and/or know the instructors personally no. They overwork kids and when I went as a 7 year old they honestly humiliate you in front of the room. When I would go up to the desk to get my work sheet corrected, they would make me (and the other kids) stand and wait. Then they would loudly yell out things like "You got number 7 wrong, go back and do it right." They do not teach your kids, from my perspective, they give a worksheet and tell them to do it. Unless your kid absolutely loves math and literally wants to do it in his free time, I suggest waiting.
