PEN - Preparing Educating Nurturing

Dear Teachers,

In the era of “hide-and-seek learning,” we understand that students may sometimes stray from the core of a lesson. We also recognize the stress and pressure you face in guiding them back on track.

That’s why we’ve developed supportive resources—key concepts, keywords, and more—to assist you in your teaching journey. We are here to stand with you, to amplify your efforts, and to be your voice in making learning more focused, joyful, and meaningful.
