Play truly is the work of children. They learn so much from playing games and interacting with other children and with adults. Games can teach language skills, develop visual and language-based reasoning, improve memory skills, and much more. Here are some terrific thinking games for preschoolers and toddlers that have stood the test of time and that we still enjoy in our house. And best yet, they have no parts to lose, and you carry them in your mind! Take some time to play these thinking games with your child.
