Autumnal Equinox Manipulative


Autumn is officially a week away.  I mean, I have already been celebrating it, to be honest.  But the day that scientifically makes it autumn is a week away.  What makes it officially autumn?  Well, the autumnal equinox, of course!

Mark your calendars, (well, they probably already are) and add a seasonally relevant activity to the lesson books.  September 23 is the 2019 first official day of fall!

I have many ideas for you to choose from today, as well as one of my own.  I'll begin explaining the one I'm adding to the ranks.  It's a paper plate manipulative that will help your learner explain the autumnal equinox.

Two paper plates, printable clipart, scissors, glue, and crayons is all you'll need to explain the lengthening day and night cycle to your learners.

Follow these six easy steps.  Then stew on some of my ideas for differentiation.

1.  Gather (or color/paint) a light blue and dark blue paper plate.

The first step to making your manipulative to explain changing cycles of night and day lengths.
2. Decorate the paper plates to represent day and night. (These particular decorations are included in the download below).
Step two in making a manipulative that explains the changing day and night cycle.
3. Measure to find the center of each plate.  
Step three in making a manipulative that explains the changing day and night cycle.
4. Then, cut a straight line from edge to center.
Step four in making a manipulative that explains the changing day and night cycle.
5.  Intersect the plates so that the bottom one (night) can rotate on to the top one (day).
Step five in making a manipulative that explains the changing day and night cycle.
6. Label 180° as Autumnal & Vernal Equinox (A&V, F for Fall or E for Equinox) 216° as Summer Solstice (S) and 144° as Winter Solstice (W). 
Step six in making a manipulative that explains the changing day and night cycle.
Now, learners use this manipulative to explain that:
  • Equinox means equal parts day and night
  • Summer has longer days than nights
  • Winter has longer nights than days
To differentiate,
  • Mark the dots for learners needing extra assistance.
  • Use protractors to incorporate mathematical precision and tool use.
  • Calculate the length of day during each equinox and solstice based on degree measurement and proportional reasoning.


This, my dear leader friends, is only one of many great ideas out there to learn about the autumnal equinox.  Feast your eyes on these:

All Ages

  • LieBackLookUp invites you to use yourself and a flashlight as manipulatives to learn about the seasons.
  • HomeSchoolSuperFreak thoroughly explains a fall equinox and provides links many more activities, videos and book ideas.


  • With GryphonHouse you'll sing a song, make some art and perform an action poem to celebrate fall.


  • MontessoriTraining provides your learners with some hands on cultural applications of autumnal equinoxes. 
  • HelpTeaching celebrates fall in many subject areas.

4 +

  • DIYHomeschooler defines equinox and provides links to several additional equinox resources and activities.
  • DiscoveryEducation invites learners to write a script for silent animation.  Then, celebrate the upcoming longer nights with nocturnal animals.
  • YummyMath looks at the equinox through math glasses.  Includes data interpretation of line graphs and a formula for calculating the number of daylight hours in any given day.
  • With SolarCenter you'll create a solstice and equinox "suntrack" model using paper plates.

With all these seasonally relevant activities to choose from, I sure hope one found it's way into your lesson books.  Here's to hoping your learners learn to love fall!
