I got the bag and trays at Christmas Tree Shop. The trays were $1.89. The metal was better than plastic for the magnetic activities.
I made tags of 30-40 minute progressions. Jordan helped me figure this out. The first one was Binghamton, NY. At this first "stop", (we didn't actually stop), I gave them each a tray and folder. In the folder were copies of games and puzzles. There were also pictures to color. When we arrived at each "tag", I told them what "game" to do.
The second "tag", I had them take out their pictures and had them color them. I judged them and gave the winner a prize. Another "stop", I pulled out a new book on CD. (I got that at a yard sale the week before with my Mom. It was a Hardy Boy book, so it was great,, we went through a few tags with that activity.)
I also put magnets on the backs of a Scrabble game pieces.
This also helped the younger ones see how we were progressing. I didn't have to answer the dreaded, "Are we almost there yet?" or "How much longer?" because they could see how much longer. Titus fell asleep when we only had about 4 more tags to go and was so excited because he looked up and said, "Mom, look! We're almost there!"
I stamped a truck and called it us. I then taped it to some bias tape and put that on a clothes pin. It moved along as we did. Here we were at the Mass border.
At another tag, I gave each of the boys a handful of marshmallows on their tray, a straw and a cup. They had to suck the marshmallows up with the straw and put them into their cup. First one done, won. Just little "games" like this helped pass the time and make good memories.
