This is our estimation
jar. One child takes it home each week and fills it up with items. They can fill
it with anything: candy, toys, buttons,
blocks, crayons, etc. You should find a note on the inside that tells the
maximum number of items to put in the jar. Keep the exact number of items
secret. If you tell one first grade friend--all of them will know by Estimation
Jar time. Let me know if you want the items back by checking the box on
the note. The jar comes home on Friday or Monday and should be returned
by the next Friday. Have fun filling it!!
