Estimation Jar



As you may know, third grade mathematicians have been practicing their estimation skills. This week Janyla filled the Estimation Jar with packets of Hershey Kisses. Throughout the week children wrote their estimates on scrap paper and submitted them to the Star Box.

Together we went through the estimates and rounded each to the nearest ten. Brennan helped us to place the numbers on the line plot.

This week we noticed that the mode was 40. The actual number of packets in the jar was 35, so our estimating skills are improving!
