Send your students home with a "TOP SECRET" envelope labeled: For parent & guardian eyes only! Inside the envelope, put the provided mystery reader information sheets inside. Fill in your own name, dates, and times. On the blank table chart, write in the dates that work with your schedule, copy it, and parents/guardians can circle the top 3 dates they can do. Have parents/guardians return the clue sheet back to you in the envelope. Students will LOVE seeing their loved ones surprise the class and read to everyone. I hope you enjoy this product as much as we do! I purchased these envelopes at Wal-Mart.
