However, I'll do my best to link to the resources I made or used. If you have a question about something, like how I did the fold or where I got the resource, please ask in the comments and I can probably tell you what I did.
For the basic structure of the pages I used this nice free Prayer Lapbook.
It has some basic questions and answers (what is prayer, where do we pray, etc) and then a section on the Lord's Prayer as a model or pattern for prayer. (I'm going to post that part in another post so this doesn't get too long).
The prayer lapbook is not a Catholic resource, though, so I made some modifications. I wanted to include some of the Catholic doctrine on prayer, so I formatted some of the Baltimore Catechism questions and answers. I didn't use everything I put here, just the ones I wanted for the present.
Here's the formatted version:
Catechism on Prayer
You can find many of the folds I used at Homeschool Share Free Templates.
Many of them were also in the prayer lapbook.
What is Prayer, When Should We Pray, Why We Pray, Does God Hear Our Prayers, How to Pray
Trifold book: What is Prayer? It uses the prayer lapbook and includes the Catechism teaching on prayer.
Prayer is the lifting up of our minds and hearts to God.
Wheel book: When Should we Pray? I put some of the catechism answers like "morning and night", "in times of temptation", "at mass". They can also be found in the printable above.
