What do toddlers know about grouping and sorting? Surprisingly, a lot! Even by seven months or so, infants can tell the difference between pictures of animals and humans, and furniture and animals. By the time toddlers are approaching their second birthday, their ability to categorize has grown tremendously. Depending on their experience with the big wide world, they can tell the difference between dogs and birds, chickens and ducks, and dinosaurs and horses. Learning to group and sort is highly dependent on experience—children who have experiences with ducks and chickens (from pictures or from farm and pond visits) learn how to differentiate these two birds earlier than those who do not. Follow your child’s interests and help him explore this fun learning experience!
