Happy Scratch Day!

UPDATED for 2017!

To mark Scratch Day, here are some teaching resources I made – mostly, but not all, to do with ICT / Computing:

Binary Numbers Quiz – binary to denary

Binary Numbers Quiz – denary to binary

Hexadecimal to Base 10 Revision Game

The MakeyMakey Visual Piano

Designed to use easily-accessible keys to play tunes on an 8-note scale, with keys that light up in appropriate colours.

Binary Maths Cards

Designed to work with the Computer Science Unplugged binary cards, I use this a tool when teaching and revising binary – a big hit with students who can come up and slap the interactive whiteboard to convert decimal to binary and back.

Checksum Game

Another one to get your students using on the big screen – introduce parity bits with this CS Unplugged card trick.

Bubble sort

A simple and pleasingly noisy bubble sort that allows students to see a bubble sort run in real time – and pick apart the code that makes it work.

Scaredy Squirrel Turns

I made this for a Year 2 class to help them learn about quarter turns (we didn’t do degrees in Year 2 then, though they probably do radians now). I got the children up to the board and asked questions like ‘how should we get Scaredy to face the bees?’ or ‘if Scaredy makes a half turn, what will he see?’ in a cross-curricular link with our literacy topic.

Scaredy Squirrel Game

People told me they were too young, but I wanted to get Year 2 coding, and invented this game with a familiar character to show them what Scratch could do. You have to guide Scaredy back to the safety of his tree, avoiding the various perils on the way. The results were, I think, a big success.
