Carla, when you say you are busy "...checking in the clubbers..." I get the impression you are referring to the Check-in List grid? If so, you CAN reduce the number of records in the grid by selecting a particular club name in the toolbar's drop down list of club names instead of the default of "All Clubs".
Further, you can drag and drop the Team Color or Grade column header into the grouping area above the grid to organize all the records into logical groups so that they match your worksheet.
Below is a screen capture example of the Check-in List grid showing only Sparks and the records are grouped on Team Color. (though you could group on Grade or Leader Name too)
