To cover some bible work for my younger kiddos, we read through this book:
It has wonderful lessons, discussion points, Q&A, in addition to a prayer. We aim to cover 1 "letter" a week. This goes along perfectly with any type of Letter of the Week program.
To help solidify the learning and bible verse memorization, I have my learning to write age kids use the this printable I created. Here's an example:
There's a page and verse for each letter of the alphabet, following the book.
It shows the verse, has an area for them to draw out an example of the verse, then the verse as handwriting/copy work.
