How many rocks are in the jar?
How many pom poms?
Challenge your kids with this fun Estimation Station math game. How close can they get to the correct amount?
I recently set up this Estimation Station to give my 1st grader a fun math challenge after school.
It took only a few minutes to set up. I just gathered a few items from around the house and had this math game ready in no time.
My daughter loved it and had a great time guessing and checking her answers.

Set up your Estimation Station
I found a selection of glass jars and loose parts. Any glass or clear container would work.
Use whatever you have. Cotton balls, beads, dried pasta, paper clips, crayons, and bottle caps are some more possibilities for an estimation station.
I also wrapped some rubber bands around a wine cork. I got that great idea from No Time For Flashcards and their Estimate-Unwrap-Count challenge.
Add a chart
I then made a simple chart with a column for each item and one row for the estimates and another row for the actual amounts.
I had everything set up on the table waiting for my first grader to return home from school.
For an added challenge, you can have your kids make their own chart.
It’s time to estimate!
My first grader took one look at the project and dived right in.
She examined the jars and though hard about her estimates.
“Rubber bands are skinny, so there must be more of them,” was one of her thought processes.
She made her guesses with lots of thoughts and reasoning. There was no haphazard guessing going on with this project.
After she made her estimates, she counted the items to check her guesses.
I had her divide the items into groups of five before counting to sneak in some skip counting practice.
We found some surprises.
Even though those rubber bands were skinny, there were only nine wrapped around the cork.
In one simple project that took me less than 10 minutes to set up, we practiced estimation, skip counting, and graphs. And, we had a lot of fun together in the process. Not bad for one simple math game!
