A cute display in the spring outside the classroom door. you could use this for adjectives and have the students write adjectives that describe them self on the petals or do an addition problem with the petals.
Have students paint circles in shades of green great bulletin board for my Eric Carle author study. Would add a writing piece where kids would paint the cover of thier favorite book and write the title and why they like it.
This voice levels poster is used in most preschools during my placesment, I think it is an effective way for teachers to control the voices in the kinder. Child also remember the colors and related voice levels that they should use inside and outside.
Chatter tracker--I like this as a reminder to students about the voice level to have during specific times of the day. I wouldn't use this exact phrasing, and I would actually make a stop light to "light up" as a reference for the kids.
