While I typically recommend more integrated ways of learning certain skills, workbooks have their place. There are times when they are great for supplemental learning and some children find it quite fun to work with them. It's all about the approach and your child's interest. Always follow your child's lead and let them explore if and how they want to use them. Keep in mind their age and developmental abilities. Having said that, these are some that I have found to be popular with children. I have also included fun activity books for travel and downtime.
