Quote from Leaning Magazine's Back-to-School Product Recommendations and Reviews: An intriguing entrance helps prepare students for a busy day of learning ahead, and this provided just such stimulation. The children used terms such as 'cool' and 'awesome' to describe it It is so nice to have borders, posters, nameplates, etc., that all fit together and show all that goes on in school, so I would certainly recommend this to other teachers.
