Paper-based Grammar Cube is a teaching-aid tool to enrich your grammar lessons. You can use it as a supplement to your regular grammar book to build a wholesome picture of English grammar for your students.
It works even better if you have interactive board in class and can use Virtual Reality models. You can find two interactive VR models here http://www.granav.com/
Holding paper model in hands as a real object helps children to explore it naturally and build a bridge to interactive VR models. Abstract grammar becomes tangible and therefore much easier to understand and learn.
This product works best for students aged at least 10-12 y.o. and older.
