Would you like to create your own simple Google Slides Warmup? Just use this template: goo.gl/eDgVdu (click the "Make a Copy" button) and edit away! If you need GIFS, here's my folder "GIF Collection": goo.gl/jxpCCK. (If you're unsure how to add the GIFS to the Slide, Slides 3 and 4 here: goo.gl/hLpu5E show you how to do it.)Enjoy! And, please, share out what you create if you are able to do so.
If you have a pdf that you'd like to enlarge, you can do so right from within Adobe Reader. Here's how: Go to "Print", then choose "Poster": Next, set the scale to "200%" for 4 pages (experiment for larger) and I prefer no overlap, so set it to 0: PRINT!!
