After being out of teaching for 10 years, I have accepted a 5th grade science class. I have never taught science, I was a middle school math teacher. I am having a little trouble finding "warm ups" to start the class and get them on task quickly. I think my discipline methods are a bit rusty and know that having an activity ready for them as they walk in will make a huge difference, I always did this with math and the students would get settled quickly. I am just struggling with this and it seems to set the tone of the class every day, so if anyone has any resources/suggestions that might help I would love them. I am filling a long term sub position with absolutely no lesson plans or outline, so I'm just kinda feeling my way through. THANKS for any help, me, my students, and my family would be grateful for any kind of help (they have to see me struggle with this)!
