This program attempts to walk a student through a complete curriculum and covers the years K-8. The student gets an avatar and explores among four different themes: pixies, pirates, animal friends and dinosaurs. Each themed area has a a series of quests where usually 6 different items need to be found. By practicing different types of problems the student finishes these stories gaining additional bonus points and character cards along the way. The actual problem sets (at least in second grade) seem fairly mainstream and concentrate on numeracy via number bonds, place values, regrouping etc. After each set is finished a more difficult one will eventually be offered until the curriculum goal is mastered. This typically take 4-5 sets of approximately 6 problems interspersed among various curriculum strands.
