Raindrop graphing on the flannel board

The flannel board is such a great teaching tool when you think outside the box a bit. This week, we turned the flannel board into a raindrop measuring graph!

With all the rain this month, it has been a good opportunity to dive into a little rain science and math. The children were each given a small measuring bottle then invited to predict how much rain their cup would get in it if left outside for the morning.

Most of the children predicted that they would get up to the number five line. One parent mentioned that it could be that the children chose four or five because many of the children are now age four and five. I thought that was a pretty good observation.

After their predictions, the children placed their bottles outside in the rain and left them for the school day. Later in the day, the children got their bottles and checked out the actual measurement.

As you can see, there wasn’t quite as much rain in their bottles as they had predicted. I was a little disappointed that we didn’t get much rain that day. I think we should do a do-over the next time our weather person says it is going to be another rainy day!

    I’m doing weather with my class as well. They have been so into estimation lately and this would be a great activity to do. Where did you get the bottles that you used?

    The way you conduct the activity it is a matter of guessing, and that can be fun in itself. If you put the bottles out in the morning, and have them make an estimate in the afternoon, before you collect the bottles, they may have picked up more signals that point to lots of rain or not. This brings children closer to taking account of helpful signs to base an estimate on.

    And, I forgot to mention: love the idea of this activity.
