Those long summer evenings can make you restless, especially if the kids stay out late. Teach your child to tell the time so that he can be home by curfew time. Telling time is a vital concept that kids need to learn by the time they are in 2nd grade. It incorporates skills such as reading, writing and counting, apart from making them aware of the value of punctuality. Once your child masters the concept of time telling, he can move on to other summer worksheets.
