Block-Posters
Purchasing posters for your classroom can quickly add up and not everyone has access to a poster maker (printer) at school. You can get around this challenge by using BlockPoster to print individual pages than then you can assemble to create a large size poster.
It is very easy, just go to Blockposters.com, upload your image, follow the prompts to download your poster, print, assemble, and post!
Here is an example of an image of the Eiffel Tower by Cyril Mazarin used to create a poster for a French classroom.
