A ten week course · grades 3 to 5

Computer science, with no computers.

Cones, string, index cards and a locked box. Your child never touches a screen, and you never buy a thing. I bring all of it.

Finding the bugThe step that was wrong, and fixing just that one.

Why this class

Why I teach this

My children are growing up around software that hides how it works. A phone sorts a list, picks a route, suggests a video, and never shows its reasoning. I want these kids to see the moving parts once, with their hands, before any of it feels like magic.

The part of computing I teach needs no screen. A nine year old can sort twenty cards on the floor and feel why one way takes longer. They can hold a yarn network and watch what breaks when one connection is cut.

I run my own tech business and I use this thinking every day. The children are not learning to code here. They are learning to take a problem apart, test it, and fix what was wrong.

I don't grade. I help while they work and I give them feedback.

The last week

They open the box themselves

On the final day the certificates are locked in a treasure box, and the only way in is to use what they learned in the first nine weeks. Nobody is given the answer. The class works it out together, and then they take the certificate home.

For families

Send your child, and that is all

What you provide. Nothing. I buy and bring every cone, card, blindfold, ball of yarn and brass fastener. No supply list, no book, no device.

What comes home. A take-home page each week with an activity you can do together, and a short note telling you what the class did and why it matters. Nothing is required and nothing is handed back in.

Screens and privacy. Children use no devices. I use a display at the front for short videos and prompts, and that is the only screen in the room. Student names live on my own class list behind my login. They are not published and not shared.

Celebration. Every child gets a participation sticker every week. There is a weekly prize draw too, and it is a rotation, so every child gets a turn before the course ends.

For teachers and co-ops

Run it yourself

The whole course is written down, so somebody who has never taught computer science can pick it up and run it. I built it that way because I needed a guest teacher myself.

Questions

Questions families ask

Does my child need to know anything first?

No. Week 1 starts with giving directions to a partner. Children who have never thought about computers are not behind.

Is there homework?

No. A page goes home each week with an activity you can do together if you want to. Nothing is collected and nothing is marked.

Is my child graded?

No. I help while they work and I give them feedback. The class is not ranked and children are not compared with each other.

My child is shy. Will they be put on the spot?

Children work in small groups that change week to week, and the closing questions are answered by the whole class together.

Really no screens?

Children use no devices. I use a display at the front for short videos and prompts. Everything they do is physical.

What if we miss a week?

Each week stands on its own, so a missed week does not leave your child stranded. Week 10 draws on all of them, but it is a group escape room, not a test.

What is the prize draw?

A small weekly prize, drawn from the class. It is a rotation, so every child gets a turn before the course ends. It is not a reward for being fastest or best.

Do you keep any information about my child?

Only a first name on my class list, behind my login, used to track whose turn it is for the prize. It is not published and not shared.

Can another teacher run this class?

Yes. There is more in For teachers and co-ops.
