Click the green flag to start. You now have to use your mouse to slide the n slider value. Once you picked a value for n, click the button "Redraw." The N-Leaved Rose will draw a different amount or peddles depending on the value of n.
I used the "Learn to Program with Scratch" book to create this project. I first downloaded the file "Ch 5 N-LeavedRose NoCode.sb2." I then used the book to make three variables and make one block. I then followed the book to create the scripts to make the N-Leaved Rose.
