We started looking at these last week.
Use the PowerPoint to work through.
Save your own copy and add your learning to it.
For some slides you will need to view as a slideshow to see the animation or to click and see the next step appear - SLIDES 7, 9 AND 13. These are for GoogleDraw, not PowerPoint but I think they give you a good idea of what to do. Explore on PowerPoint to find the way you do it there!
I am looking forward to seeing your vector drawings!
