Growth mindset/LEARN bulletin board/banner. Powerpoint file with 420pt font. Each slide has an indicator to show which fonts get printed on which colour paper (you can use any colour, but Astrobrights are always my favourite! Simply print on 6 different colours of paper, laminate (for durability), cut, and enjoy!
