Welcome to Module 2!
What would you do if I said walk straight, turn right? Well... You'd probably just walk straight and take a right at the door! Robots, though, just don't get it. They'd walk straight for 1 step, turn right, and stare at a wall. Worse yet, if you told them to walk straight, turn right, and walk straight again, they'd just walk straight into the wall! And they'd crash right through it if you didn't tell them not to.
Step 1 - Read the orange chart above and get ready to learn about speaking to computers in their language. Watch the video about writing instructions or algorithms HERE.
Step 2 - Graph paper programming. Look at the symbols and images on this PAGE (make sure to scroll down to the 3rd page on this link). Use the symbols and a scrap piece of paper to write the algorithm for one of the images. Have someone else figure out which image your instructions would create. Try it again.
Step 3 - How are you doing? Try the Graph Paper Self-Assessment. You don't need the actual paper. Just think your way through each task.
Step 4 - Think you understand algorithms? What things in real life require specific steps in a specific order? Add to our collection of real life algorithms!
