I have never heard of snap can.
Homework is different than tests. Returning it in a timely manner is vital. It’s not always easy to do for the teacher, but it’s very important.
Just because someone knows something doesn’t make them able to teach it. Teaching is a gift. You have it or you don’t. All the education and certification in the world can’t change that. However, teachers can be taught more effective ways to teach. Continuing education is a great way. Communicating with parents is another. I learned a ton just listening to what they had to say.
I no longer teach...now I homeschool my jr high kid and preschooler. I have been AMAZED at how much more attuned I am to his strengths and gaps in learning. We won’t always homeschool, but I recommend it highly. At least for a year or two.
Oh sorry, snap scan. It is a very small fast scanner to file for computer.
Yes, the math teacher was the daughter of somebody connected with the school, but all the kids in the class who cared about their grade had tutors too because she just couldn’t get her knowledge across and was in her own world.
