As you may know, third grade mathematicians have been practicing their estimation skills. This week Joanne filled the Estimation Jar with bouncy balls. Throughout the week children write their estimates on scrap paper and submit them to the Star Box.
Together we go through the estimates and round each to the nearest ten (or hundred - depending on the estimates). The estimates are placed on the line plot. This week we noticed our estimates were way off. As you can see the mode of this data is 40-50. However, there were approximately 130 bouncy balls in the jar. After much discussion, third grade mathematicians decided that our inaccuracy was due to the various sizes of balls in the jar. We will use this mistake to inform our estimates in the future.
