Take a sheet of paper and plot a five-pointed STAR. Make a block 'DRAW STAR' in My Blocks that glides to the 5-points of your star and draws it. Press the SPACEBAR to Draw. If you are using a tablet or iPad and your on-screen keyboard covering half the screen is a nuisance) try the bumped up version of the STAR which doesn't require you to press the spacebar. It's at: https://scratch.mit.edu/projects/282411564/ (FOOTNOTE: The apple has nothing to do with drawing the STAR. It's a coordinate reader !)
I began on paper and decided to draw the star on the xy-grid-30px I used the 'Talking Mouse' to tell me the coordinates.
