Blocks and building toys have been around as long as toys have been in existence. It is an innate urge within children to build and create things and often blocks are a simple way to learn and play while expressing their interests. If your daughter loves princesses, she might make a castle. A son who loves farms, could build a farm. At the same time, they are practicing STEM skills and strengthening their math and science skills. Those skills will help them throughout the rest of their lives, as they enter high school and college. Spatial reasoning, cognitive development and problem-solving are all practiced when kids are playing with blocks. Do not mistake this time as mere play, but pay attention to what they build, how they think and what they try to share with you. Use play as an opportunity not just for learning but for quality time and bonding.
