Estimation

This week we have worked on practicing estimating. We have read two exciting books and each day we practice estimating the number of things in a zip-loc bag. Yesterday we estimated a bunch of crayons, made our guesses on post-it notes, and then counted to see the real number (26). We then discussed which guesses were guess estimates. We also watched a clip from discovery education on how crayons are made and the large amount of crayons that are made each day.
