History of Math Timeline
This is a HUGE timeline - 10 feet long by 1 1/2 feet tall! It shows ancient math and how it relates to current Montessori materials! This pdf must be taken to an office supply store for output (unless you want to somehow print it in pieces). Office Depot charges by the foot. You can take this on a jump drive and they can even reduce it to 1 feet and it will be less expensive. An absolute wonderful way to get kids excited about math again!
