I just had conferences this week and wanted to share something that I do to help parents remember their date and time. I send home labels that say:
To the parents of __________________
Just a reminder that your conference is scheduled for this evening
at 6:20. I look forward to meeting with you! (Happy face, my name)
I stick the label on the child's coat or shirt and it has REALLY cut down on the number of parents that don't come. It's better than a note because we know they can get lost! Hope this helps you!
