ETC Montessori is famous for the timelines we produce. We were the first company to begin printing our timelines on recycled plastic back in 2003. Today, it is not uncommon to find guides who still use their timelines after more than 10 years. Every timeline is a work of art, usually taking over two years to produce, going through the process of image rights acquisition, fact listing determination, verification and editorial content.
Constructed from recycled plastic, our timelines do not require lamination, will not crack around the edges, and always lay flat. Our large full size timelines, usually measure 17.5" x 9', and allow for up to 6 children to comfortably work and explore.
