Fourth graders have started a new module focused on computer science. We reviewed how computers use inputs and outputs and discussed how computers use a combination of 1's and 0's called binary to store data. They then had a chance to decipher secret codes in binary to unlock messages. Students then learned about a way to store black and white images in a computer with run length encoding. Students created a pattern of out of white and black shaded squares (pixels) and then wrote the code to create the image. Everyone had the opportunity to trade their directions with a classmate who then tried to recreate the image based on the directions. It was a great to see everyone try so hard to decipher each other's code!
