Evolmic Kids's math track runs 17 levels, from counting through addition, subtraction, multiplication, division, and a final mixed-operations review. Each level is a short set of 10 questions, marked instantly so a child sees right away what they got right and what to try again.
Math is free to practice as a guest, right from the homepage — no account needed. A Parent can also create an account to assign specific levels, track progress across multiple children, and see weekly stats on the dashboard.
