Here is what I put in their books this time. I found everything online for FREE!
I had a pencil case with a crayons and pencils and a pen on each book.
There were some scavenger hunts and letter word games.
The kids enjoyed this one- find the restaurant
I printed one of these pages for each. I could have printed a couple I think.
Highlights for Kids has several hidden picture pages you can print for free
KrazyDad has GREAT word searches for all levels
I also included several blank pages.
My kids spent HOURS plain M.A.S.H., a made up game about how your life will turn out.
I found these little books on Amazon for about $1.00- $1.50 a piece. They had tons. Hidden pictures, state questions, find the differences, etc. I actually stashed these in my purse; they are tiny. I used them at restaurants. The kids loved them and they are the perfect size!
I hope some if these ideas work for you for your summer travels!
