Diagrammet a Process

Av Anna Warfield

Vi ger och får instruktioner hela tiden, vare sig det handlar om en webbplats, ett recept på middag eller vägbeskrivning till postkontoret. Vi går igenom olika processer också, liksom många naturfenomen. Livscykler, rutiner, fotosyntes, matsmältning - processer finns överallt! Instruktioner och processer är så mycket lättare att förstå när de åtföljs av bilder. När vi berättar om en process eller skapar ett sekvensdiagram, kan vi fokusera på diskreta steg, orsak och effekt och sekvens.

Storyboard Text

  • Maybe I can help.
  • GAH! Math is so stupid! It doesn't make any sense!
  • This protractor thing is impossible!
  • I will show you how to use it. Well, step 1...
  • 
  • Make sure the protractor is not backwards! It makes life so much easier if you can read the numbers.
  • Before we measure, tell me if this is an acute, right, or obtuse angle.
  • It IS acute, so that means it measures less than 90 degrees. We already know the answer is between 0 and 90 degrees!
  • The line doesn't reach the numbers!
  • Acute?
  • There are two parts of the protractor to help you get the angle in the right place: 1) an upside-down T at the bottom middle 2) the base line (0 degrees or 180 degrees)
  • We want to place the protractor on top of the angle so the middle of the T is at the vertex.
  • Acute angle! 40 degrees! Take that MATH!
  • Rotate the protractor so the vertex of the angle is still at the T, but one leg of the angle is lined up with the 0 degree line.
  • That's OK. Don't you remember that definition about angles? Two RAYS with the same endpoint? Rays go on forever, so we can just extend the legs of the angle.
  • The legs of the angle are extended, so we just need to read the numbers. Our options are 140 degrees or 40 degrees. Which is it?
