Question: Why can't I skip my 20 minutes of reading tonight?

Answer:  Let's figure it out mathematically!

Student A reads 20 minutes five nights of every week;
Student B reads only 4 minutes a night. . . or not at all!

Step 1: Multiply minutes a night x 5 times each week.
       Student A reads 20 minutes x 5 times a week = 100 minutes/week.
       Student B reads 4 minutes x 5 times a week = 20 minutes/week.

Step 2: Multiply minutes a week x 4 weeks each month.
       Student A reads 400 minutes/month.
       Student B reads 80 minutes/month.

Step 3: Multiply minutes a month x 9 months/school year.
       Student A reads 3600 minutes/school year.
       Student B reads 720 minutes/school year.

Student A practices reading the equivalent of ten whole school days a year.
Student B gets the equivalent of only two school days of reading practice.

By the end of the sixth grade, if Student A and Student B maintain these
same reading habits,
   Student A will have read the equivalent of 60 whole school days.
   Student B will have read the equivalent of only 12 school days.
One would expect the gap of information retained will have widened
considerably and so, undoubtedly, will school performance.  How do you
think Student B will feel about him/herself as a student?

Some questions to ponder;
   Which student would you expect to read better?
   Which student would you expect to know more?
   Which student would you expect to write better?
   Which student would you expect to have a better vocabulary?
   Which student would you expect to be more successful in school and in
life?

Why read 30 minutes a day?

If daily reading begins infancy, by the time the child is five years old,
he or she has been fed roughly 900 hours of brain food!
Reduce that experience to just 30 minutes a week and the child's hungry
mind loses 770 hours of nursery rhymes, fairy tales, and stories.

A kindergarten student who has not been read aloud to could enter school
with less than 60 hours of literacy nutrition.  No teacher, no matter how
talented, can make up for those lost hours of mental nourishment.

Therefore. . .
   30 minutes daily: 900 hours
   30 minutes weekly: 130 hours
   less than 30 minutes weekly: 60 hours
