# Snow Day Math: Data Management

We had our first Inclement Weather Day on Friday, November 1.  In my school, and I think this is true in many schools around here, we double up classes on a snow day.  Few children come those days and it’s a great chance for kids to try things out in another room, see old friends, and get to know or reacquaint themselves with a new teacher.  For a teacher it’s a great chance to get caught up on things. I worked on some necessary paperwork that has been bugging me. The teacher I partnered up with did some Running Records.

For the last 80 minutes of our day, my teaching partner and I had the students together.  We decided to have them gather data this year on Snow Days.  We wondered how many children were in the school that day, and what kind of information we could get from the numbers.  We sent teams of students to each classroom to ask how many students were in each homeroom that day. We then gathered together and reported our data.  We organized it all on a chart.  We had a great discussion about the numbers:  Which class had the most students? Which class had the least?  Which classes had the same?  We wondered if the numbers will stay the same for every snow day.  Were the numbers smaller than usual because it was the first snow day and the day after Halloween? We noticed that some of the older classes didn’t have many children in them and the younger classes generally had more.

We even calculated the total number of students in the school. My grade 3 students were able to do this!!  We had a great conversation about a strategy for adding up 20 numbers.  I think they’ll be able to do this independently next time…or nearly independently anyway.  I suppose that depends on how long we wait until the next inclement weather day.  I’m thinking now that we should figure out what percentage of the student population came that day.  We were a group of grade 1, 2 and 3 students, so percentages are above our curriculum expectations. However, I bet I can procrastinate house keeping for a few more hours by figuring out how to make some circle graphs of this data.  They should certainly be able to read those.

Our plan is to do this every time we have a snow day, then compare the data over a long period of time.  I wonder what trends we will see!   I’m excited to share this data with the children who were not in school on Friday and see what they notice about the data.
