It's not much, but I now present the few words that form the opening salvo of this Teacher's Dictionary. Feel free to add to it any terms that you have heard or thought of yourself!
"Choir practice" -- Code name for after-hours meetings held by some teachers, typically on Fridays, in an establishment where discussions are held, friendships are strengthened, and alcoholic beverages may or may not be consumed. See also TEAM BUILDING, GROUP MENTORING, and GARDENING WITH GRANDMA.
"DJing" -- The very annoying practice of some administrators, when using the school's Public Address system, of droning on and on, as many morning DJs do on the radio. What should be a 30 second announcement turns into a 6 minute beat-down as the speaker feels the need to comment extensively on the short announcement.
"gradecation" -- Taking a day off merely for the purpose of catching up on grading papers. Gradecations are typically NOT fun.
"maximum kiddage" -- The largest amount of students that can fit in a certain area. When planning for pull-out math tutoring, I tried to give each small group maximum kiddage so as to get the most children covered.
"milk carton photo" -- A student who is consistently absent or missing from class. Similar to the "Have you seen me?" photos on the side of a milk carton, but with less calcium enrichment.
"repeat customer" -- A student who has been retained for another year. Some kids just like 3rd grade so much they want another shot at it.
A small beginning, I know. But perhaps in time, this will grow to be worthy of its own internet page. Let the submissions begin!!
