With the help of social media, the students have received hundreds of cards, including international ones from Japan, Switzerland, the United Kingdom and France.
When students received a card from a new state, they put a heart-shaped sticker on a map to track their progress.
Second-grade teacher Chelsea Horton found this project idea from Facebook, but didn’t expect it to be so successful.
As of Feb. 8, the students are only missing cards from Idaho and Wyoming.
If you would like to send a card, it can mailed to Lagonda Elementary School, Attn: Second & Third Grade, 800 E. McCreight Ave., Springfield, OH 45503.
