Be an Assessment Junkie! ✅ Descriptive feedback ✅ Narrative commentary ✅ Vital for learning ✅ Low stakes 👏 We can live w/o grading; but it's hard to live w/o assessmt + feedback. #AMLEcommunity

Elementary kids shouldn’t have more than an hour or two of work per day. That’s it. That’s all they need. Many miss teachers. Some are scared & anxious. & they just want their parents to be parents right & not feel like they have to be the education warden. Focus on play & family

Lucy: What we DO NOT want schools to do is to cancel all teaching for a month to do running records. Sadly this is so common and we lose much teaching time! #leadingwell #G2Great

Teacher Evaluations should: 👍 Make Teachers BETTER, not bitter 👍 Build Morale, not destroy it 👍 Be Often 👍 Not be the only time admins are in classrooms 👍 Offer Practical Ways to Improve 👍 Lead to a two sided, calm Conversation 👍 Never be about, "Gotcha" 👍 Be Encouraging

The BEST idea ever! Put a Draw-It slide as the first slide in your @Nearpod presentation! Gives the kids something to do while they are waiting on the others to login. The kids loved it!
