It's no secret. We have lots of books in our home.
Some are ours, but a lot we borrow from friends and local libraries.
Each year, as we progress through history in a four year cycle, I try to find a variety of children's books set in, or about the time period we are studying. This is harder for ancient history, but quite easy for our current time period (1400's/1500's to 1850).
Due to the over abundance of selections, I started a new system this year. I still read aloud several selections to the children, but the extra books get placed in a basket. Each child is encouraged to read a few extra books each week.
To further encourage them, I made a graph that records each child's progress. We have four children with four different reading and comprehension abilities. To make it fair, we set guidelines for how many books must be read for each particular child to color a box.
7th grader - read 4 picture books / color 1 box; read 1 chapter book / color 1 box
5th grader - read 2 picture books / color 1 box; read 1 chapter book / color 2 boxes
3rd grader - read 1 picture book / color 1 box; read 1 chapter book / color 4 boxes
Preschooler - listen to 1 picture book / color 1 box
Eventually, we will add some incentive prizes,
but for now, we are simply implementing the system.
