Another Routine to Build Number Sense - Count Around the Circle

I just read the book Build Mathematic Understanding Every Day in Grades 3-5 by Jessica Shumway. In her book Jessica has shared some routines to incorporate into your daily routine in grades 3-5, I would say some of them would also work with grades 7 & 8. Her book is available from Stenhouse Publisher.
The routine I found most powerful was one called Count Around the Circle. In this routine students are in a circle and count from a certain number by a certain amount. It is important to note, Jessica suggests starting with an easy count to set up the routine. For example counting by 1's, 5's or 10's and starting with 0. So the first person counting by 5's from 0 would say 5, then next 10 and so on.
Some things she calls "expectations":

1.  Everyone listens and keeps track in their head.
2. Give think time for people who need it (don't give them the answer) Student can ask for help if they feel they can't get it after some think time. She suggests choral counting circles if there are issues. 

One other thing that I think is REALLY important is recording the numbers as they go around the circle. This is where the discussion and the real "math talk" comes from after the count. See the example below:

   

                 

The book has tons of examples and ideas for counting around the circle - check it out here
