Last Thursday was our 100th day of school this year! We had fun celebrating "hundredness" throughout our day. In the morning, we warmed up by writing numbers from 1 to 100-- a lot easier and quicker for us to do than it would have been earlier in the year!
In Number Corner, we have been recognizing "decade days" all year long. So on the 100th day, we celebrated our tenth decade day by counting by tens to 100, practicing writing the number family we had just worked our way through (the nineties), and ordering some random numbers between 1 and 100 from least to greatest.
We also practiced locating and identifying numbers efficiently in a hundred grid by coloring in the numbers that were called out. Gradually, students figured out what the picture was and could call out numbers for the class to color as well.
We made a trail mix snack of 100 little items. We had to first figure out how many of each to use if we wanted equal amounts, since there were five snack foods. We figured out that two groups of ten of each would work.
We got out the collections some students had brought in and had to prove that there were indeed 100 items in them. We grouped them in piles of 5 or 10 in case we lost track counting along the way, and some of us wrote equations to go with our groupings. We counted and recounted one anothers' tracks, Legos, pennies, Cheerios, gummies, sea creatures, and puzzle pieces.
During writing time we took a break from the serious informational writing we've been working on to write and share about things we wished we could have 100 of.
During reading time, it was a treat to nibble on our 100-item snacks while getting absorbed in our books.
