Estimation Jar

Hello everyone! I have an estimation jar as part of our calendar activities board. Students guess how many objects are in the jar and estimate the amount. We then count the amount together as a class.

We start with smaller amounts and then use greater amounts as the students become more proficient with their estimations.

Students record their answers on these recording sheets.

This estimation jar poster can be used at your calendar area or math center.
