When our son was that age, we would sometimes:

* play chess (this was and is a favorite)
* work on a project (right now he's 8 and is helping my husband diagnose problems with a tube amplifier and repair it)
* work on a snap circuits set
* play Texas Hold'Em poker
* work with clay...this allowed for infinite creative possibilities. We recently made a chess set of Star Wars characters
* go for a post-dinner walk around the neighborhood and talk
* read parts of the newspaper and discuss current events
* invite friends or neighbors over for dinner and spend the evening talking with them
* go to a local concert - we live in an area with many classical, jazz, etc. concerts that have reduced ticket prices sometimes
* play together on a computer game, alternating turns. When our son was that age, he really loved Zoo Tycoon. We would take turns building exhibits and enjoyed that.

Have fun and don't limit yourself!
