The "Back to School Color-Coded Fun" activity bundle is a great way to introduce yourself and your students to each other.
There are 3 card groups; red for the 'Would you rather' questions, yellow for Math, and blue for English. Use the Math and English just for generally assessing the students so you can get an idea of where each student stands in those areas without turning it into a big deal.
This is for that first week or two of school when students are eager to be back, but not that eager to learn! This will help you get them moving, and talking, and engaging with you as well as one another.
And the best part is there is no loser - everybody comes out a winner with this fun get-to-know you/assessment activity.
You can use it at the beginning of the school year when all the kids still want to make a great first impression, and again later in the year when you've all gotten to know each other. You will see how far they've come; even the shy ones who will have slowly, but surely, matured and come out of their shell.
