Last year I did a Lego Fractions activity with my students. I put the Legos in baggies with a card that said something like "Which fraction are blue?" I used people, trees, flowers, doors, windows, and just regular blocks. I went to get the activity ready today, and I was completely shocked to find that almost all of my "fun" lego pieces are gone! No flowers. No trees. Only 1 person. Last year I did this activity the last week of school, so I know they disappeared this year. I know that they are not anywhere else in the room, because the Legos are always in one cupboard (I cleaned the cupboard out). I just re-arranged my room a few weeks ago, so the pieces aren't hiding anywhere. They are simply gone. I am shocked, because I had this set for 6 years now with no problems. I also paid about $120 for it. We had a lot of indoor recess this winter, because it was so cold, and Legos were definitely the most popular activity. I'm actually pretty sure I know who it was, but he moved away last month. So, what would you do? Obviously, no more Legos this year. I plan on giving the class a talk, too, but I feel like there isn't really anything more I can do. I think I mostly just needed to post to get it off of my chest, and I knew you guys and gals would understand!
