History of Computers Lesson 9: Minicomputers and UNIX (PDP-1, Spacewar!, PDP-8, C) - printable lesson, ages 11-14

A ready-to-teach lesson that follows our free video, step by step.

Watch a part. Pause. Talk. Try it. Then press play again.

The story: a computer with a screen that needed only one operator, a space battle game at MIT, the $18,000 PDP-8 minicomputer, and UNIX: begun on a little-used machine, rewritten in the C language, and then moved to other computers.

What you get (13-page printable PDF):

- A one-page guide for the grown-up, with the exact times to pause the video

- Key words, and a "think first" question

- Four pupil pages, one for each part of the video: what we just heard, two questions to talk about, and something to try

- Two worksheets: a "chalk disk" with a list of where each word is stored, a matching task, price sums, a "Move it" game that runs one program on two pretend machines, and a cut-out timeline

- The story in four pictures, and an 8-question quiz

- All the answers, teaching notes, and the sources for every fact

For ages 11 to 14 (works from 9 with help). About 45 minutes. You need a pencil, a rubber, scissors and 12 counters.

Every drawing and every word is our own. The free video is at kitson-workshop.pages.dev/#history
