BCS Esti-Mysteries

After attending a workshop given by Shelly Moody and Valerie Glueck, BCS fourth grade teachers Shawna Lachance and Heather Hollinger decided to do Steve Wyborney’s Esti-Mysteries through an interactive bulletin board! 

Students have to guess how many items are in the picture. Each day there are one or two clues posted, and every morning students are able to look at the new clue and change their estimate.

The students really enjoy it and look forward to it in the morning.  It’s also generated some wonderful mathematical talk!
