Most elementary school students enjoy passing out Valentine's Day cards and treats. I used to have the kids decorate brown or white bags with their name and hearts. This year, I raised the bar and created a design challenge and competition with the help of my colleagues. The results were impressive to say the least. We had students design (at-home) collection boxes ranging from a Lego conveyor belt candy depositor to a soccer goalie that moves back and forth. Our students had a great time inventing and voting. We used Google Forms to make voting easy. Prizes were awarded to each overall winner in the 4th grade.
