Pop Toobs (a.k.a. Rapper Snappers) are well known in Occupational Therapy for a variety of activities and benefits.
Pop Toobs have a way of drawing and engaging children more than most other sensory tables. The Pop Toob sensory table is extremely simple, but incredibly beneficial. The list of potential benefits is lengthy and includes: fine-motor, crossing the mid-line, auditory and visual feedback, resistance to muscles (finger, arm and shoulder), tactile stimulation, and cylindrical grasp.
Endless shapes and tunnel mazes, provide unlimited creativity.
Pop Toobs can be twisted, bent into a variety shapes and stretched. They can also be connected together. Paired with wooden marbles, in a variety of sizes, students have the opportunity to problem solve by getting the marble(s) in one end and out the other. I should give a warning though. This sensory table is quite loud, from both the wooden marbles and when a student expands or contracts the tubes. I added thick shelf liner to the bottom of the table to reduce some of the noise, but its still going to add distinctive noise to your classroom environment.
Natural wood marbles are only one of many options.
One of my goals is to bring in more natural elements, throughout my classroom. I chose natural wood marbles to offset the simple man-made sensory tools and because I felt they would be safer to use than glass marbles. In the past, I have used pom-poms, pony beads and chickpeas. Just make sure the objects you choose are small enough to keep from getting stuck inside the tubes. Pop Toobs can also be used by themselves.
