I have developed this reading log over several years of tweaking it to meet all of my needs. The log is designed to monitor the length of time the child reads each night and how many books she reads and how many are read to her. The log also monitors who is working with the child at home. The other sheet (I print this double-sided) includes instructions for the family member to help increase the child's fluency and comprehension at home.
Two words in the instructions are in red and bold to indicate they need to be changed by you to match the number of books you send home.
Designed for First Grade with "book baggie" or "take home reading folder" use, you can modify this to meet your requirements and grade level. If you would like family instructions for emergent readers, please take a look at my Kindergarten Reading Log (with family instructions) here
