Desk Arrangements

So I wanted to do tables with roller chairs this year, but it just isn't going to happen. My vice principal advised me to work on small group instruction this year (for the new teacher evaluation yearly goals) so I have decided to place my desks in rows with desks in pairs. I was just going to do straight rows, but I'm thinking that I might be able to do a horseshoe pattern since I do not have as many desks as last year, but it might still be tight. I'll decide next week when I get back in my room and reorganize everything. Right now though, I made my seating charts for straight rows since I know I will definitely have enough space for that.
