Help Please - New K-5 Technology Teacher

Hi-

I am so glad that I found this forum.  I was just hired on as a K-5 Technology teacher.  I had applied for a different position which was filled, but they wanted me to be part of the team.  There is very limited lesson plans left for me.

Can I get some suggestions for first weeks lessons, rules, etc???  I see each class once a week for a 45 min. block.  I have about 400 students.  

I have a curriculum map, but just don't have a good sense of a starting place or any solid plan for at least the first two months.

Any info is greatly appreciated.
