Mirrors are important tools that help to build a young child's self-awareness, self-esteem and cognitive development, and that's why our Mood Mirrors are essential furnishings for every Early Learning classroom. The facial features of our Mood Mirrors are etched into safe, shatterproof acrylic and help a child identify, understand and express their own mood or the mood of other children. The set includes one each of the following: WB0035 Happy Face Mirror, WB0036 Sad Face Mirror, WB0037 How Do I Feel Today? Mirror. Attach to a wall or other surface [mounting hardware not included] or can be hand held.
