Vinyl DIY Long Black Strip

(1 customer review)


The Montessori Long Black Strip is a powerful tool for teaching children about the vastness of time and our place in the universe. It is a long, black strip of vinyl that is unrolled on the floor of the classroom. The strip represents the 4.6 billion years of Earth’s history. The teacher will point out the different eras of Earth’s history, such as the time when the Earth’s surface was magma, when the Earth began to cool, and when different creatures came to prominence (like the dinosaurs!). At the very end, the teacher will also point out the time when humans first appeared on Earth.

The Long Black Strip is a valuable resource for Montessori elementary teachers who want to help their children develop a deep understanding of the history of the Earth.

This is a semi-DIY project, see the blog post on how to make this material before purchasing!


This Long Black Strip is accurately scaled and matches the color scheme of the Rhyme and Reason Timeline of Life and the Clock of Eons,Ā I think the matching colors really helps integrate the three lessons together which helps children build an awareness for the vastness of time.

0.25″ is equivalent to 1,000,000 years.

    I like the quality of the material, how Emily thinks about every little detail and that she shares the step by step with a video on her website.
