Block Posters is a web-based tool to which you can upload a high quality graphic then divide it into letter-sized chunks for printing. Print out each section and put them together on a poster board to make your own poster. If you find a great infographic or poster that you want to display in your classroom, Block Posters is a good tool to use. Block Posters is also good for creating large jigsaw puzzles. In the video embedded below I demonstrate how to use Block Posters.
