Teaching children about mitzvot can become a fun family tradition.  Make a special bowl that has age appropriate mitzvot on small papers to pull out once a week as a reminder to do something good for someone else.

You can download 30 "easy" to do mitzvot here.

Cut them up and put them in a pretty bowl or container.  Each week on Shabbat you can pick a different mitzvot reminder to do the following week.
