I decided to use that method in order to see what Eaton wants to do that day. If that was a math, language or something else. I put maximum 10 pages of worksheets of different topics every day. Most of the time they are related to the subject I want to teach in particular week.
There are thousands of free worksheets on Internet. Just browse Google "worksheets for kids" and go to images. I'm sure you will find something interesting for your kid as well.
I also tear pages from books and put them in the plastic cover for protection. This way I can use it with my younger one later on.
Here are some pictures of what I used previously with Eaton:
On the first page I always put pages from Flash Forward Reading book I posted previously.
Those worksheets that required writing something down I changed to 3 years old kid friendly versions using velcro.
Some Polish language pages.
Whenever I see something interesting on a Web I print that out immediately, and put it in my designated folder, so I have it available anytime.
Websites I recently visited are:
Kids Learning Station
Tons of free stuff for joyful learning!
