There are quite a few students who have grown accustomed to weekly/biweekly ice packs, and since enforcing stricter ice pack rules, I now often send them back without doing anything.
"I bumped my knee on a chair yesterday."
"Well, I'm glad you are able to walk well and there is no swelling or redness. You are stronger than you think! Go back to class!"
"My side has been hurting this week."
"Does your parent know?"
"Well I'm glad to see there is no bruising, redness, swelling, or tenderness when I touch it and you are walking well, so you can go back to class!"
(without hesitation) "The other day, a boy opened a door and it hit my cheek and it still hurts."
"Well, it's great news that there is no redness or swelling or anything there. I believe you that it hurts but it looks like it is healing great, you can go back to class!"
Or, today's 4th grader who should make it into the "Good Kids" thread,
"My eye is red because I have allergies, this happens a lot. I splashed water on it already, which is what I usually do, and it feels better."
"That's great! Has there been any drainage?"
"Did a teacher send you here?"
"Would you like a cool wet paper towel to take with you?"
"No, it feels better"
"Well, you did a great job! You can go back to class."
But we should never underestimate the importance of our teaching! One kindergarten teacher asked us today to explain to a scared student who had been told "if that gets infected your arm is going to get chopped off" that his elbow scrape was not infected and his arm was not going to be chopped off--and I went through all the signs of infection and how I did not see any of them present. He assessed his own elbow and seemed to calm down. That was exciting!
