Most children are unable to differentiate between different colors until at least 18 months of age, which is also about the same time that children start to notice differences and similarities between textures, sizes, and shapes. However, while children can start to differentiate between colors around 18 months, it can take until age 3 before children can fully understand the difference between colors and name them.
Shape activities can help preschoolers develop problem-solving skills. Cut and paste activity are one example. When a child recognizes the characteristics of a square, he can match it with the missing square shape on the paper. Shape recognition can also help when putting together puzzles. If he pays attention to the shapes of the pieces and the shapes of the openings in the puzzle, he can determine the correct spot for each piece.
Do you ever wonder why we put so much emphasis in the toddler and preschool years on teaching colors and shapes? Teaching children about colors and shapes is a great way to give them some vocabulary for describing the world around them. As children learn to identify colors and shapes, they can sort and classify objects in around them based on these attributes.
