Golden Time ideas

As you may have read a couple of blog posts ago, I've recently started working with some new classes. This is the first time I've had such young learners, and I'm learning quickly!

I've decided to implement a traffic light system, but at first I wasn't sure what the consequence of getting moved to a red light could be. Then I found out about Golden Time, which means time at the end of the week when the learners have time to do activities of their choice in the classroom. The idea is that any time a student gets put onto a red light, they lose minutes of Golden Time.

I love the idea of Golden Time, and it seems like a really good idea to combine with the traffic light system, but I'm not sure how I can implement the concept in my setting.

That's where I'd like to ask for your advice.

I'm working in a school during their lunch hour. My students are 6 and 7 years old, and the classroom that we use is a secondary school room. So, it's neither my room, nor their room. There are no resources in the room that I can use, apart from the tables, the chairs, and the blackboard. There isn't a lot of floor space, unless the tables are moved - which is problematic, as they have to be returned to their original positions at the end of the lesson.

My idea is to join the tables together into groups of four, and have a different activity at each table for the last 20 minutes of the last class each week. The activities need to be easy and quick to organise, and self-explanatory, as there won't be time to explain the activities and for the students to have enough time to enjoy them.

I'd really appreciate any ideas or advice you could offer me on this.
