Make estimating a part of your morning routine. Place small items in a clear plastic jar. The number should not be larger than most of the children can comfortably count. As the children arrive, encourage them to look at the estimation jar and make their best guess about how many items are inside. During large group, open the jar and count the items. Emphasize that you are looking for an answer that is about right, rather than precise. This could be done in large group.
