Welcome to a magical laboratory where letters come to life! Children help find letters for "word-bots," funny robots who love words! Compatible with the Square Panda Phonics Playset, early learners discover letters and sounds using robots to manipulate letters by sounding them out, transforming them into objects, shrinking them from uppercase to lowercase letters, painting them, and blowing them dry! With each experimental activity, children hear letter sounds in new contexts, reinforcing the most fundamental skills in reading readiness! Perfect for children learning: the Alphabet, letter sounds, phonemic word onsets and vocabulary Features: Encoding and decoding phonemic sounds Expressive phonics 26 phonemic sounds x 5 robots = lots of phonemic discoveries!
