I gave them each a little sheet of paper (which you can get here) with some math terms and items that we would be studying this year. Things like negative numbers, percents, and decimals all made an appearance on the sheet. I then asked them to look through magazines, newspapers, and the internet for examples of each. They could be creative in how they interpreted each of the categories (ie: a box of cereal from an ad could be considered a polygon), but each category had to have at least two things that were representative of the math. If they couldn't find a suitable picture in the magazines, newspaper, or internet, I did allow them to draw a picture....though I discouraged it slightly. I just wanted them to actually see how math was all around us in the every day objects that they would be dealing with and drawing the picture didn't seem too "authentic" to me.
Once all of the pictures were cut out, they then mounted them on a piece of paper (I just cut some tag board in half...easy peezy) and created a collage of their math findings! I did ask them to label the collage, so most kids just cut out the labels from the scavenger hunt page itself and glued it on.
These really came out so cute! I mounted them on the bulletin board for all to see, AFTER we discussed how the math we were going to be learning really was found all around us! The kids enjoyed it too....though I suspect they like anything that involves cutting. ;)
