Anxiety can look like a kid who refuses to listen or someone who needs a little push to speak up. Once you recognize the signs of this mental health challenge, you can make sure your students get the support they need. If only you could spend your day teaching—just that, not all the other parts that come with the job. Paperwork, meetings, lunchtime supervision. The list keeps growing longer. Classroom teachers are the first line of defense for noticing when kids need outside intervention.
