Lot of 6 Versa Tile Sets and 6 Math Activity Books; Grades 2--6

6 Sets of Versa Tiles and 6 Activity Books. There are no grades on the covers that I could find but as a math teacher I would guess the 2 Activity Books are labeled "Intermediate" (likely grades 4-6) and the other 4 Activity Books are likely for grades 2, 3, and 4. The tiles are in good used condition and none of the cases are broken or cracked. The Activity Books are in good used condition as well, with no writing in books, no torn pages, covers in great condition. Eta VersaTiles is a hands-on learning system designed to help students build math kills through self-correcting activities.  Key features of VersaTiles: They are a Self-Correcting System: The core concept of VersaTiles is its self-checking mechanism. Students work through activities in a workbook and then use numbered tiles to indicate their answers on a special answer case. Once completed, they flip the case over to reveal a pattern of colors or numbers that correspond to the correct answers, allowing for immediate self-assessment and feedback.
