Shamrock Estimate

We invited children to examine a jar of shamrocks today and make their best estimate of how many were in the jar. We were impressed by their reasonable guesses - 54, 67, 81, etc. - as this shows they have a solid number sense. No estimate was unreasonable (0, 1 000 000). 

We used a 100 chart to help us organize the shamrocks into an accurate count since it was such a large collection. 

There were 81! The children were excited to realize their estimates were so close!
