There are many different varieties of educational TV character toys available on the market. Many are designed to teach basic language and/or number skills. Other TV character toys are designed to be used as part of a larger learning system, where children can learn about colours, sounds, textures and develop their problem solving skills.
Though TV characters are fictional and may not actually have a lot in common with your children, most children do identify to some degree with the characters in their favorite shows. They are open to learning from these characters because they can naturally accept their understanding of the world. Children who seem scared of the learning process will find educational TV character toys particularly non-threatening.
Educational TV character toys are ultimately designed to make learning fun for children.
