Thanks Dottie for the cool book idea - Times the Fun Way book - we ordered this after I saw your post and it came in the mail today....most of the lessons are really cool and I can see how they can help a child visualize that particular math fact. My son was SUPER excited to see the book because he has been dying to learn his tables and has a horrible time with memorization. I feel really silly but had never been shown the way you can do 9's times tables on your fingers - the book was easy to understand and is well written - he already learned the 4x4 lesson (you have to be 16 to drive a 4x4) and thinks it's cool that he can finally keep that in his memory :-) Thanks!
