Common Core Aligned: Estimation Jar Grades K-3

Estimation jar lessons are one of those activities that can be organized many different ways.  Plus you can teach a variety of skills with a jar.  Who knew a jar could be so useful in the classroom?

I found this jar at Target today for $3.68.  It is a gallon size Ball Mason Jar.  It almost Easter, so I bought some plastic eggs and egg-shaped gum balls.  They are colorful and add seasonal fun to any lesson.

If you want to add measurement to the lesson, bring in other sized jars such as pint and quart size jars.  One day put the same number of gum balls in each of the jars.  Of course, the smaller jar will look fuller.  Will students estimate a larger number if the jar looks fuller?

An estimation jar lesson is a lesson that can be taught a variety of ways.  There are more Common Core standards that can be used with this activity.  I included a few of the ways that I've used with my classes in the packet.
