Activities from children’s courses

These twenty-four activities come from computer-skills and digital-literacy courses for children aged 6 to 13, and every one of them works in English and Spanish. I designed them and built each one as a standalone page on the design system of GrassLMS, the LMS I wrote.

Most of them copy programs that children already use, such as File Explorer, Chrome and Google Docs, so the practice carries over. A mistake costs nothing here, and children keep trying things instead of waiting to be told what to press.

The spaceport course

Ten computer-skills tasks share one story about a virus in a spaceport, and a map ties them together. Each task saves its result in the browser, so the map clears a sector once its tasks are done and plays the ending when all four are free.

A copy of File Explorer with folders and a list of things to try

Practising with File Explorer

Sector A starts in a safe copy of File Explorer, where children aged 8 to 11 make, rename and move folders and then follow a path down to one file, in English or Spanish.

Folder names next to an empty folder tree

Rebuild the folder tree

The child puts a scattered folder tree back together from the indentation of the empty slots and learns that indentation shows how deep a folder sits. The task is in English and Spanish.

A grey circuit board with numbered parts and a colour code

Repaint the circuit board

Every part of a grey circuit board has a job, and the child works out that job to find its colour in the code, first on a board of four parts and then on one of six. It works in English and Spanish.

A small pixel rocket plan next to an empty grid

Copy the pixel rocket

The child copies a pixel plan square by square onto a blank grid, which trains careful reading of rows and columns. It works in English and Spanish.

A Google Docs copy with a misspelled radio message and the Find and replace bar

Fixing a message with find and replace

A radio message has five misspelled words and an impossible launch year. The child fixes it with Find and Replace in a copy of Google Docs instead of retyping, in English or Spanish.

A symbol key and two messages written in symbols

Reading a message written in symbols

The child decodes two words with a symbol key that holds one decoy, a symbol that appears in neither message, so careless matching shows up at once. It works in English and Spanish.

A warm-up question about bold text above a document

Formatting a mission report

Five warm-up questions check that the child can see formatting. Then the child applies bold, italic, colour and size to a report while a checklist ticks off each change, in English or Spanish.

A health bar duel with a question about struck-through text

Defend the server from the virus

This is the check after the report, in which children aged 9 to 12 name the formatting on five samples. Every wrong answer explains what the right one looks like, in English or Spanish.

A slide deck copy with download and upload steps underneath

Fixing a slide deck

The child downloads a broken .pptx and fixes it in any slide program. Back on the page, the file is checked slide by slide without leaving the computer, in English or Spanish.

The first of five locked doors with a question about the launch year

Five doors between you and Andy

Children aged 8 to 11 open five doors to free Andy, and each door asks about a task they played around the spaceport. They need the launch year that could never happen, the second word from the cipher, the spacewalk they struck through, the room an .mp3 goes to and which task went with which job.

Everyday computer skills

These activities copy the programs children use at home and at school, so what they practise here carries over to the real thing.

Staying safe online

Both activities train a habit that a rule on a poster does not give, which is reading the address and the source before trusting a page.

How the web and AI work

Here children look inside the technology they use, by switching parts of a web page off or by watching a neural network guess.

Making things and showing them

These activities are about building something with a purpose and then talking about it in front of the class.
