Beneath all the rancorous debate in D.C. education are countless teachers who spend long hours preparing lessons, mentoring children, grading papers and working to get better at their craft.

This week, parents and students and leaders from across the city have together waged a campaign to thank educators for their often-unsung work.

Across the city, PTAs have put on special luncheons. Principals have thrown ice cream socials and treated teachers to free sessions with massage therapists.  D.C. Public Schools urged parents and District residents to take to social media to show their appreciation for teachers, tweeting thanks with the hashtag #dcpslove.

Mayor Vincent C. Gray (D) surprised two teachers — Sarah Burke, a stalwart at School Within a School who is retiring this year, and the lucky winner of a raffle at Washington Math Science Technology Public Charter School — with the hottest tickets in town, to tonight’s Wizards playoff game against the Indiana Pacers.

Education Secretary Arne Duncan and Jill Biden — wife of the vice president and a teacher herself — paid a visit to Marie Reed Elementary in Adams Morgan. And a couple of show biz celebrities also saw fit to take part at the urging of Chancellor Kaya Henderson.

“Let’s make this a trending topic all week long!” Henderson wrote in a letter to parents Monday.

This is  the last day to weigh in during what is, officially, Teacher Appreciation Week across the country. Most teachers don’t mind, though, if recognition for their efforts comes at other times of the year.
