From PBS KIDS, the number one educational media brand for children, this fully-illustrated, thoroughly engaging book introduces important concepts for pre-schoolers.Extensive research has proven that little ones learn best when they are engaging with an adult. Every page of 100 Concepts for Preschoolers is designed to spark conversation between the grownup reader and the preschooler. From life cycles to opposites, to early math and literacy, to sorting and rhyming, the playful captioned pictures and themed pages encourage vocabulary growth and reasoning skills. Children three years of age and up (and their parents) will have fun exploring key concepts, while preparing for pre-school, and for life!
