One of the teachers at my school is helping organize a canned food drive in conjunction with the hundredth day of school. After the winter holidays, there is a dramatic decline in the food donations to food banks. This is way to help the situation and also integrate math. I've seen lots of ways to keep track of the number of the canned goods each grade or class donates but I like the visual idea of each students coloring a can/box for each can/box they donate. He is trying to expand the project so I wanted to pass the idea to all the wonderful teachers in blogland. He's a great guy so don't hesitate to contact him for more information on the project. It would be great to see the difference the project can make across schools, counties, and states.
