Smart Numbers are among the first wooden connected toys designed by Marbotic, combining traditional toy design with digital technology. Inspired by the Montessori Method, a child-centered educational approach, Smart Numbers interact with educational apps to help your kids explore basic math skills. 100% safe for children, Smart Numbers do not require batteries, wi-fi or Bluetooth. Instead, they work with the static electricity generated by our bodies. To use, open any relevant app and stamp one of the wooden numbers on your tablet’s screen. The tablet will recognize which number it is. Then, kids can discover various mathematical concepts using the wooden blocks on the tablet screen. Smart Numbers turn passive screen time into active learning time. For ages 3-8.
