It's a fun way for children to learn about counting and colours, while they play hide-and-seek! These little dinos tuck away inside the eggs for surprise counting fun. Each numbered and coloured egg holds a corresponding number of dinos inside, so children learn about number correspondence too! The set's 55 dinosaur counters come in shapes of famous dinosaurs. You'll find one T. Rex, two apatosauruses, three triceratops, and so on!
