An intro to programming concepts with Scratch Session 10A of 10 sessions Final Exercises

Session 9 goals Putting elements together Teaching Playing Telling a good story

The top line is 10% longer, why?

Make a better script Ask the user for a number N Ask the user for a percentage P Find a new number that is P % larger than N. Make lines for N and for N increased by P percent. Why not make a line for N decreased by P percent?

Other exercises Dr Salehi has a good exercise Use multiple sprites Use multiple frames How does it flow? How to control the frames?
