We've been preparing for the 100th Day of School since the year began. Of course, right now we have no idea when that day will be! The day we return after all this snow will be the 100th day.
We have taken pictures of items from the first day. On day one we took a picture of 1 thing. On day 2 we took a picture of 2 things. On day 3 we took a picture of 3 things. And so on.
We haven't managed to keep up each day so every once in a while we have to catch up with a few pictures.
As the year has progressed the students have become more sophisticated in their counting of the items. You will notice they are grouping items in 10s to make the process easier.
