Printable Timeline of Life – Montessori Second Great Lesson

(6 customer reviews)


This Timeline of Life has been completely redesigned to match with our current understanding of  evolution. The red lines represent a simplified phylogenic layout, that is accessible to lower elementary children and exciting for upper elementary children.

The timeline covers the Precambrian to modern day and features 78 hand drawn creatures, all five mass extinctions, early mammal lineage and much more that is absent from Maria Montessori’s original timeline.

Read a full script for the Second Great Lesson to accompany this timeline on the blog.

Read an in depth description of what makes this timeline special on the blog.


In the Second Great Lesson, the Coming of Life, the story of how life began and evolved is introduced to children. The lesson is accompanied by the Timeline of Life which is then available to the children as a reference material for reflection, research and hands on work.

  • Final timeline measures 18″ tall x 72″ long
  • 78 hand drawn creatures
  • All five mass extinctions are present
  • Plants and Fungi are present in this timeline (They are missing from the original and most other commercial timelines)
  • Integrates with the First Great Lesson by including the Precambrian Era
  • Integrates with the Long Black Strip lesson by having a scale at the bottom
  • Print at Home: One PDF file that you can print at home on letter sized paper and tape together. This option requires 18 sheets of paper. (This can also be great for students to have their own copy of the timeline!)
  • Print with your own professional: One hi-res PNG file that you can send to a professional printer.

    Love this work! Detailed and high quality. I used the printing company suggested, but chose banner style (with the provided measurements) with no grommets. Saved a lot of money and it is still very nice and durable.

    This is such a beautiful timeline. I’m so glad that I purchased this. Both of my kids have enjoyed it so much and it is definitely something that we are going to enjoy working with for a long time.

    What a wonderful product! Beautiful artwork and very engaging! Many of the timelines I’ve encountered for the Second Great Lesson needed an update, and Emily’s is much more scientifically accurate and stunning to boot! Right now, I just have it printed out, but I’m waiting for my canvas one to arrive. I can’t wait to present this to my daughter!
