About Addition Adventure
Knowing addition facts by heart frees up working memory for harder problems later on, like multi-digit addition, subtraction and multiplication. This game gives quick, repeated practice in a low-pressure way.
Younger children (Kindergarten to 1st Grade) should start with numbers up to 10. Kids in Grades 2–3 can move on to 20 and 100, while numbers up to 1,000 suit Grades 3–4.
