The 4C's are important 21st century skills that naturally connect to the skills in STEM/STEAM. These posters come in two different sets and have a black and white bookmark.
Set 1: All in different patterned purples with Collaboration, Communication, Creativity, and Critical Thinking
Set 2: Posters in four different colors (Red: Collaboration, Blue: Communication, Yellow: Creativity, Green: Critical Thinking)
This is a great companion product to my STEM and STEAM Poster Set found here https://www.teacherspayteachers.com/Product/STEM-and-STEAM-Poster-Set-1981275
