Even the class estimation station can be a part of Dr. Seuss math celebrations. After reading One Fish, Two Fish, Red Fish, Blue Fish, have students estimate the number of fish in a jar. Use fish manipulatives, goldfish or gummi fish to fill the estimation jar. Have students post their estimates on post-it notes, or fill in a class recording grid.
Download the Estimation Station file which includes a class recording grid as well as a form for the actual counting of the contents. Some teachers keep these records in a class estimation counting folder or binder for future reference. This is especially helpful when trying to develop how the size of a unit impacts the number of units that can fit into the same jar. Keeping the documentation allows teachers to call upon the information in future discussions.
