The “rule of three” is a time-honored pattern in literature, scripture, and advertising. I find that when I write, subconsciously I am often searching for that third example. Three seems more powerful than two or one. When I write, I ponder, type, and delete over and over.
A master teacher once taught me to conclude lessons by asking: “What did you learn? What did you do? How did you feel?” Recently lesson plans moved from a 5-point LEARN model to a 3-step lesson plan: What, Why, How. This shift is intended to tighten instruction for more explicit teaching. What are we learning? Why are we learning this? How do we do it?
Today I was introduced to another Three: Know, Do, Be. What do I know? What will I do? What will I be? This group of 3 seems very powerful to me. It frames the idea that what I know affects what I do and how I walk in the world–what I will become. To me this is hopeful. This idea matters. This is worth all my daily effort. Knowing, Doing, Being. Another form for faith, hope, charity.

This post is food for thought. Now I am going to be looking for those threes!

I love how you included scripture. Know. Do. Be. That is what we need to carry out in our faith life, daily life, teaching life.
Yes yes yes
i agree
Was never a fan
of the LEARN lesson plan model
looked nice on the paper
bit didn’t feel real
felt clunky
There is power in the three. I love the ones you mentioned. Some time ago, I wrote about them in literature, in writing and used the term pitchforking. It’s one of the tools to combine sentences. I hope it’s okay if I share that link here. Would love to hear your thoughts. http://alicenine.net/power-of-three/
