This set of early flashcards, packed with preschool activities for learning numbers, will help children to appreciate the natural world. These flashcards are ideal for parents who want to foster a love of nature in their children from an early age. The cards go from one to 20, and inside each one are activities based on key early learning number concepts such as numbers, counting, matching, sorting, opposites, sizes, shapes, and patterns. Card number 20 is a double gatefold that opens to reveal an illustrated number line. The fold over format is perfect for parents and children to look at together, and for putting up around the home to help reinforce number learning.
