I love colorful displays, so this crayon classroom door display "Get Ready for a COLORFUL YEAR! OUR NEW PACK" is an idea I'd love to use. This idea would also look great as a Back to School bulletin board display. Put all the kids names up to be a crayon.
BAck to school activities: Icebreakers: Back to School Board Games: FREEBIE is a collection of 3 printable Back to School Board Games by Games 4 Learning. Perfect as 'getting to know you' games for the few first days of school!
