My son is not school age yet, but when I was growing up, my mother always took us shopping to pick out gifts for all our teachers. I intend to do the same.
She also had us bring in end of the year gifts, does anyone still do that?
I teach preschool, and many children bring end of the year gifts. Some do not- and that's OK! What I love are the notes from the parents- they are always so grateful to see the growth in their children over the year.
My favorite end of the year gift was a hydrangea. I had become close to the family and to the mom, having taught all three of her daughters. I planted the hydrangea in my back yard, and I take a picture of it every year, showing her daughter who gave it to me how much it has grown over the years. It's a nice way to stay in touch with them!
