This is a positive sign to inspire students to try their best. Give them the knowledge to know sometimes it will be hard, but you will always be there for support.
This can be a small poster for a desk picture frame or used as poster decoration in the room. The print is an 8 1/2 by 11 PDF file, but could be sent to be printed on larger paper. No matter the size, you could probably print this poster at your school!!
You could also print this and put it in an inexpensive frame as a gift to a teacher!
