Easy Autumn Estimating Jars

Modified: Oct 8, 2024 · Published: Oct 30, 2013 by Emma Vanstone · This post may contain affiliate links · 4 Comments

I love autumn, and my 5-year-old loves exploring and numbers, so today, we combined all three to make a fun estimating activity using estimating jars.

We traipsed through the woods collecting leaves, pinecones and horse chestnuts as we travelled.

Once back home, we laid all our ‘treasures’ out to dry and returned to them the next day.

How to make estimating jars

  • A collection of leaves, pinecones, acorns or anything else you can count.
  • Different sized jars.

Estimating Jar – Instructions

  • Look at all your objects and jars and decide where you will put them.
  • Can you estimate how many of each item will fit in the different jars?
  • Are you right?
  • Can you draw a table to record your results?

More ideas

What are the biggest and smallest things you can fit in your jar?

Can you fill a jar with something and ask a friend to guess how many items are in it?
