3 years & up. Keep classrooms healthy during cold and flu season with the Social Distance Discs from Learning Resources. These durable multicolor foam discs help give kids an easy visual lesson in the social distancing recommendations that help stop the spread of sickness. Simply spread the Social Distance Discs out on the floor, then use the included measuring cord to make sure there's enough space between them. This reusable cord measures more than 6.5" long, which makes it easy to measure out distances that conform to both American and European social distancing guidelines. Made from soft, washable foam, the discs are a snap to sanitize. Plus, with 30 discs in all, you'll have enough for the entire class! The Social Distance Discs also come with an Activity Guide filled with ideas for how to teach your kids new healthy habits! Mats are 10" in diameter.
