On Wednesday we celebrated our 100th day of school with several activities focused on 100.   During math, students searched the room for ten small pictures of sets of objects in groups of 10 to 100, recording the number of each set of objects once they found the pictures.  They also played a board game that involved moving a game piece to 100 and made strings of 100 beads organized by color in groups of 10.  Later in the day they worked in small groups to build with 100 geo-blocks, 100 keva blocks, 100 pattern blocks, and 100 paper cups.   Throughout the day, children searched for 100 numbered tiles hidden around the room and matched them with their corresponding number on a 100's chart.  Several students also decided to write numbers up to 100.  It is always exciting to mark this milestone in the school year.
