This is a set of 4 DVDs introducing the "Challenge 1st Grade" educational materials and content for new elementary school first graders. It's from about 10 years ago, so it's old. The discs have scratches. No special case is included. One disc is a 3D animation, but the 3D viewing glasses are missing and not included. Although there are no glasses, it can be played in 2D. Please consider this item only if you understand that it is a used item. #Challenge1stGrade #New1stGrade #ElementarySchoolEntrancePreparation
