Reaffirm your child's learning. I have seen that you do much better when you build up your confidence by rehearsing. Read every day. If children keep practicing their reading skills, they will return to school in the fall ready to pick up where they left off. Be visitors in your city, town, or village.
Every town has interesting places to explore.
Look in the local papers for activities for you and your children. Go to a park you've never visited. Help your child learn to use maps. Teach your child skills for life. Summer is a great time for a child to learn how to use tools or to cook meals.
