Our lightweight beams not only offer a fun, balancing challenge, but also provide opportunities to reinforce knowledge pertaining to letters of the alphabet, numbers and shapes. Designed with safety and young children in mind, our beams are constructed of three-inch foam enclosed in 18 oz vinyl. Each beam ends in Velcro!” so you can easily attach multiple beams to create an angled obstacle course or one long beam. We offer a set of three beams that include the entire alphabet, a single beam that includes numbers one through nine and another single beam that contains a variety of shapes. Each beam is 4″W x 72″L x 3″H. Royal Blue top surface with Red base.  Recommended to be brought in from your Outdoor Classroom or used inside.
