We send these kids to.... school. Places with lots of people and social expectations. Places that are busy, noisy, bright and distracting. Places where we are asking them to learn things that are HARD!
Is it any wonder that sometimes kids find it overwhelming. For some kids this means going inside themselves and shutting down learning. For some kids it means going walkabout around the classroom at inconvenient times. For other kids it may mean a meltdown of one kind or another.
What these kids need is a way to let their teacher or teachers aide know that they are struggling before they get to the point of no return. What the adults need is a way to help the kid quickly and effectively get back in a good space for learning.
