Use the above Lenten Calendar's suggested daily activities with "dry erase stickers" to create a big "at home" reminder each day or for certain days of Lent.
Have kids create and decorate a "Lenten dry erase sticker" in Sunday School and give them a printed calendar of suggested Lenten activities to take home with it. Kids or parents write the daily suggested activity on the dry-erase sticker in the morning and place it where the family can see it, such as on the refrigerator. Families can post a new activity each day or on certain days that practically meet the family's schedule/needs. The Lenten practice activities can be adapted by the family.
This reminder placed in a high-traffic area creates a big "point of discussion" where family members are likely to see it daily.
Various types of "dry-erase" stickers and contact paper are available at online retailers.
