Place several small objects in a clear plastic container. The number should be within the children's ability to count, usually 10 or less, but possibly up to 20 as the year progresses. During large group, ask the children to estimate how many items are in the jar. Connect to benchmarks of five or 10 by showing a jar with five items, for example, and comparing the original jar to it. Ask, “Do you think there are more than five here, or fewer?”
