Devotions at Home: A Tutorial includes devotional suggestions for use with the Lutheran Service Book and makes suggestions for additional resources.
This PDF includes a chart for reading through the Book of Psalms in 30 days.
Also, just so you know, The Story Bible is broken down into 140 sections, which would give you one story a day, five days a week, for 28 weeks. That’s pretty good for ages 3-8! Great for devotions at home with younger ones!
Here is a link to a page that sorts CPH Bibles according to age. It also has 5 Bible reading plans you can download and follow, including a one-year, two-year, Bible narratives, chronological, and daily lectionary. 🙂
For reading plans through the Lutheran confessions, you can go here for a summer plan, here for a yearly plan, and here for a Lenten plan. (By the way, Luther’s Large Catechism is great reading for middle schoolers and older.)
