If you happened to catch the talk on education this morning, Monday, September 14th, on Your Morning Tradition, the following St. Thomas Aquinas prayer is what we prayed. Feel free to copy this for yourselves and for your children.
Ineffable Creator, Who, from the treasures of Your wisdom, have established three hierarchies of angles, have arrayed them in marvelous order above the fiery heavens, and have marshaled the regions of the universe with such artful skill,
You are proclaimed the true font of light and wisdom, and the primal origin raised high 
beyond all things. Pour forth a ray of Your brightness into the darkened places of my mind; disperse from my soul the twofold darkness into which I was born: sin and ignorance.
You make eloquent the tongues of infants. Refine my speech and pour forth upon my lips The goodness of Your blessing.
Grant to me keenness of mind, capacity to remember, skill in learning, subtlety to interpret, and eloquence in speech.
May you guide the beginning of my work, direct its progress, and bring it to completion. You Who are true God and true Man, who live and reign, world without end.
Amen.
