My parents came to visit this week.
(Hence my absence....mom and I were busy rearranging and organizing! :)
My dad introduced us to Numbrix Puzzles. Have you seen or done these?
My oldest loved them, so I searched and found a website full of them. I think I'll throw these in for fun in her daily work once a week. This site has a few options and difficulty levels.
I'm also going to take these into my Essentials kids as well.
