Students write letters by hand or on screen. Penny Post drafts a warm, age-appropriate reply, and nothing reaches a student until their teacher approves it and prints it on real paper.
About 20–25 minutes of teacher time, spread so no single day can break it. One capture, one review sitting, one print job: no single step that can eat a Friday.
Students write to Penny on their stationery, or type at the class station. Notebook paper? Fine; the app sorts it out.
Pencil and paper welcome!→Photograph the stack inside the app, the same day. Nothing saves to your camera roll.
→About two minutes later the queue is ready, sorted needs-attention-first.
One pass per letter, side by side: the scan, the typed transcript, Penny's draft, the stamp. Approve, edit, or send back.
→Approved letters drop into the batch as you go; print the day before Mail Day. Letters still in review ride the next cycle.
→Hand out envelopes, tap “delivered”, and watch them tear in. Next week's stationery arrives attached to each reply.
And the loop begins again…↻ One exchange a week keeps a whole year of writing practice going.
Penny's reply below is the real print template, footer and all. What you approve is exactly what prints.
Dear Penny,
We went to the science museum and I saw a real dinosaur bone. It was bigger than my dad! I want to be a paleontologist but I can't spell it. What is your favorite dinosaur?
Your friend, Owen
Dear Owen,
A bone bigger than your dad — incredible! You spelled paleontologist almost perfectly: p-a-l-e-o-n-t-o-l-o-g-i-s-t. My favorite dinosaur is the triceratops because of its three horns. If you could dig up any dinosaur, which one would you hope to find first?
Warm regards,
Penny
…and Owen is already asking when he can write back.
Themes are how you steer each response. Pick one or combine a few. Every stamp changes what the pen pal's letter works on.
Set themes per student, per group, or for the whole class, and change them any week.
Penny is a motivation engine, not an instructor: she creates writing volume — a real audience that always writes back — and the teacher's instruction does the teaching.
Students with a reliable, authentic audience write more, try longer sentences, and like writing better — that's what pen-pal classroom research and the broader authentic-audience literature show. Penny makes that pedagogy reliable: she always writes back, and the teacher approves every word.
Penny Post drafts; you decide. Every reply waits in your review queue until you approve it.
Friendly-letter units live in grades 2–4, and that's where independent reading begins. Penny's reading levels, themes, and stationery are tuned to exactly that span.
The sweet spot. Weekly letters slot into the writing block you already teach, matched to each student's reading level.
Emergent writers draw as much as they write, and replies need reading aloud. We'd rather say “not yet” than do it badly.
At ten, a pen pal everyone knows is pretend starts to feel like an assignment. Fifth grade needs a different shape; it's on the roadmap.
The free pilot is four full letter cycles — a complete friendly-letter unit, free. The keepsake from those cycles downloads free, forever, whether you continue or not.
P.S. Your students' first letters are closer than you think.
