I use this product in my first grade classroom at Open House. The students hold the banner in front of them and parents can take their picture with it as a keepsake. I also take their picture with the banner on the first day of school to save for an end of the year memory book I make for the students.
The product includes three different banners for each grade level. I suggest printing on cardstock, and laminating. I place a magnet on the back of mine and stick them to my white board at a "picture station" at Open House. When the students are finished taking their picture with the sign, they place it back on the board for another student to use.
These banners are designed in color AND black and white.
