Large magnetic chart is great for use in the classroom for easy organization. It even resembles a ruled notebook page with a red margin and three blue circles so it looks like it's been hole-punched. But this chart offers a convenient write-on/wipe-off surface and measures 12" x 15". Write notes with dry-erase or liquid chalk markers. They easily erase so the surface is ready for your next bright ideas. Chart is also magnetic so you can attach it to any magnetic surface, including file cabinets and refrigerator notes.
