Elementary TPRS/CI Question

We don’t talk much about using TPRS/CI instruction with really young kids. But some of us teach at those levels, certainly we have Eric and others. Here is a question that I hope gets lots of answers:

…how can I make this method work for kindergarten? I only have 45 minutes with each class once every six school days. How should I modify TPRS for this situation, if at all…?

All answers and ideas on this are welcome!
