Pixel Programming

Make art using pixels (post-it notes). Work in teams and see if you can make your program perfect!

Plan

  • What supplies will you need for this activity? 
  • How will you display the instructions and the programs? 
  • Where will you do this activity? 

Do

  • Have everyone work in pairs. 
  • Give each pair two different colours of sticky notes. 
  • Practice coding together as a group using program 1 (see materials list). Choose which colour you will start with. 
  • When everyone has completed program one, give each pair a program sheet and a solution sheet. 
  • Start with one person per pair trying to code off of the program sheet. The second partner should check the solution to see if it’s correct – if it’s not, work together to “debug” the program, or correct the mistake. 
  • Switch roles. 

Review

  • Was it easy to follow the program? 
  • What did you learn about coding with pixels? 
  • Were your patterns close? Or did you need help debugging your program? 

Materials

  • Post-it notes in two different colours (10 per pair) 
  • Printed copies of the programs and solutions for the main activity. 
  • A way to display the instructions for everyone to see (e.g. an overhead projector, or a printed copy per pair). 
  • Paper and pencils  

Keep it Simple

Work as a big group to give instructions and have everyone follow the program in small groups or pairs – working together will help you to follow the pattern more easily.  

Take it Further

Practice following a few programs to get the hang of how they work. Then, write your own code for your partner to follow. Were you able to write a code that your partner could understand?
