When I did the Jesse Bear unit with my boys I really wanted some of those cute multicolored bears that come with little colored plates or buckets for sorting. At the time I didn't have the money so I came up with this idea instead - it's free and works just the same! My county has us throw away the lids on beverages and then recyle the actual container. When doing so, I noticed that the lids came in an array of colors so I began collecting lids from different beverages - oj, soda, grade juice, milk jugs, ... When I had enough, I wrote color words on paper plates that matched the colors that I had collected. The words were written with crayon and matched the color red. I spread out the plates on our kitchen table and the boys sorted them by color. We have also sorted by size. For those of you on a budget like me, this is a free alternative to those cute bears.
