Thinking like a Mathematician

For the past few weeks we've been looking at measurement - linear, volume, mass, and area.  Last night Ms. Lirenman had us go home and think about our answer to this question - if an item is bigger does that mean that it is heavier than an item that's smaller?  Many of us went home and thought about it and this morning we had to tell Ms. Lirenman what we thought.  I think she was a little surprised by most of our answers because we were sure that a bigger item had to weight more than a smaller item.  Boy were we wrong though.  We used our huge class teddy and a small box of math tiles and realized that just because something is really big doesn't mean it's really heavy.  Obviously we have a lot more to learn, but thankfully grade one isn't even half over yet.
