# Snow Day – no-printer-needed computing-themed activities for those at home #SnowDay #UKsnow

If your younger kids are at home but you don’t have access to a printer then we have some computing-themed activities that you can do on a computer to keep them entertained. (If you do have a printer there are also printable versions available too).

All of our free CS4FN magazines and booklets can be read as a PDF on a computer, and of course our CS4FN blog is designed with online reading in mind. Items highlighted in yellow here can also be done without a printer.

## 1. Egyptian kriss-kross (.pdf, .xlsx)

There’s also an Egyptian word search which you can use on a PDF with the highlight function to select the words as you find them. More Kriss-Kross puzzles below…

## 2. Symmetrical pixel puzzles (.xlsx)

Symmetrical colour by number pixel puzzles are a square grid with half of the information given to you. There are two tasks – (1) follow the numbers’ colour key (e.g. 4 = green, 5 = blue) to colour in each square – by changing the cell’s background colour, and (2) copy that information to the half of the grid that doesn’t have the numbers in, as a mirror image. “This can also be used as an introduction to the idea of compression – if you know something about the properties of a picture you can reconstruct the image despite storing fewer numbers!” You can do these puzzles in a spreadsheet.

## 3. Maths kriss-kross puzzles (.pdf)

Our two Maths Kriss-Kross puzzles require you to do a little bit of arithmetic first before entering the answer into the puzzle (PDF version for doing on a computer), and writing in the whole calculation. For example 1 + 2 = ? would be written in a space for 5 symbols, like this

## 4a. Technology kriss-kross (.pdf)

There’s only one space ‘touchscreen’ can fit and once it’s there it will help narrow down which other words can fit around it. You can do this puzzle on a computer, no printer needed. Do you know what all the words in our technology kriss-kross puzzle mean?

## 4b. Some more interdisciplinary kriss-kross puzzles (.pdf)

Each requires a bit of computational thinking to come up with a strategy to fill the puzzle in, but the actual puzzle content might be about animals or different words to spell.

## 5. Word caterpillar patterns (.pdf)

For younger children our caterpillar patterns look at similar sounding (and spelled) words, with a gap to fill in a missing word. Can be done on a PDF on a computer too (or with a printer). There are also number caterpillar pattern puzzles which use coloured dots (e.g. 4 = • • • •) as a counting puzzle.
