Mobiles, Master Dictionaries and um...(insert another M word here)

So, lately I seem to be on this mobile kick. Not exactly mobiles, necessarily, so much as things that I could hang from the ceiling with fishing line, because I always feel like classrooms with dangly things are stupendous. So far, I've come up with two ideas. A Dia de los Muertos & Halloween compare/contrast mobile. I'm not entirely sure how I would fanangle it yet, but it would look like a skull on one side (the DDLM side) and a pumpkin on the other (Halloween). The kids would have to write three facts about DDLM and three about Halloween (on their respective side) and then color the mobiles. It's kind of a basic, easy assignment, but it would dress up the classroom a little. It can also be adapted for the Christmas season by doing three things about Christmas in America on one side and three things about Noche Buena on the other side (I'm thinking this would be legit because it would be examining Christmas as it is the most predominantly celebrated December holiday in the US).

I also started having thoughts about a Master Dictionary. This one is sort of iffy, but what I would do is...have a binder with trading card protectors inside of it, and cut index cards to fit the holes. Then, whenever there was a new vocab word, an index card with the word in English, in Spanish and a picture (maybe, depending on the verb) would be added to the Master Dictionary...alphabetized, obviously. I'm just not sure how much actual work it would be, how effective it would be, and how much trading card protector sheets cost (I want those because they're segmented, as oposed to just normal plastic protectors which are a whole sheet).
