All this information will be recorded on a large chart for use during the activities. The third graders could use an amount up to five hundred pennies. They would first take group guesses. Then about half of the pennies would be taken out of the container and counted. The groups then make a guesstimate.
All information is recorded on a large chart for later use.
It would be beneficial at this grade level to make copies of the charts for all the students. The fourth graders will use an amount of pennies up to one thousand. The groups will make a guess. Then about half of the pennies will be counted and weighed and a group guesstimate will be given. Then one hundred pennies will be counted and followed by a discussion of the size of the pile.
