I've done this bulletin board every year, and the kids (and adults) love it! I send out a letter to the parents asking for random items, and this is what I got this year:) The item to search for changes every day.
I like the idea of it but those letter with the zigzag - so difficult to read - would do my head it. Would look better in all black. Poster could do with a bit of sprucing up as well. Growth mindset bulletin board
