There are a few “sing-along” hymns in 3GRD-4GRD Latin. I have them on a youtube list here, including a sung version of the Pater Noster that we like.
Here you can find the Pater Noster and Gloria Patri spoken slowly or quickly in Latin. YES! However, his Table Blessing is SO FAST, we can’t use it.
An alternative site is THIS ONE. He recites the Our Father in English first, so you need to skip ahead to :45, if you just want the Latin. He does the same for the Gloria Patri, but his Table Blessing is at just in Latin and at a nice, slow speed.
I also have the lyrics and prayers in my Memory Book post here.
