6-y-o has a Lent stretch to pray for someone each day. He's done it twice, sort of:
"I hope my friend ____ is a good boy/doesn't get sick/whatever"
which is not exactly a prayer.
My thought at this point is to say, "I hope so too. Now let's ask God to make it happen." And then I do it.
Any further thoughts?
I would definitely have him pray, and you teach/facilitate.
"I hear and I forget. I see and I remember. I do and I understand."
I was brought up using the 'teaspoon' prayer, tsp (like in cookery books) Thank you, Sorry, Please
You could link that into the Lord's prayer (Matthew 6:9–13)
Thank you: Like worshiping God:
"Our Father in heaven, hallowed be your name."
Sorry: Recognising where you've gone your own way and not God's way:
"Your kingdom come, your will be done, on earth as it is in heaven."
"Give us this day our daily bread, and forgive us our debts, as we also have forgiven our debtors. And lead us not into temptation, but deliver us from evil.'"
But in answer to your question, how can your son be more specific: Maybe drawing, or modeling with Play Doh, the person he wants to pray for would focus his mind more on what is going on in their lives, what they need, etc?
There's also the ACTS model -
