This check in can be used in a few different ways.  
I like to ask about specific times of day and jot that down or ask the child to write it or draw that time of day next to the number.
eg: what number were you when you opened your eyes this morning?
Got home from school?
At break time at school?
Thought about doing your homework?
After you completed your homework?
A check in is super handy for getting a conversation going. Use it as a starting point and then use open questions in response to answers eg: "tell me more about that"
