First of all, I applaud you to be able to keep 30 kindergarteners on task with ANY program you do!!
That said, I think if you remember the first rule of any management program, and most definitely with Daily 5--TAKE YOUR TIME!!
Those first few weeks of school should be spent getting your kiddos to build stamina in the early lessons. (Refer to the book and here on the website).
When it says "day 1, day 2, etc", think in terms of accomplishments--when you've accomplished what it suggested for Day 1 (although it may be 4 days for your group), then start the suggested Day 2 lessons. Make sense?
These are general suggestions, and those with similar experiences with large class sizes will be able to give more "one the job" suggestions
