Fill various small containers with activities or hands on stuff. One tub could have Moon Sand with some scoopers and spoons, one could have cards that you sew with shoe laces, once with mega blocks, etc. Any inexpensive activity will do. Then take a picture of each one and print it out on a card. Put all the cards in a small box. During the day you can hand him the box, he can point to the one he wants to play with, and then sit at the table with the activity. Set the timer for about 15 minutes. We call this "table time."
Also, when you say that he loves to run around and climb on everything, do you mean in a typical 2-y-o fashion, or is he more active than most? If you mean that he is more active than most and you are trying to keep him busy so that he is not doing these things, also clean up his diet and eliminate toxic household and personal product. These things can affect behaior. You can contact me through my site for more information on this www.LiveWellShopSmart.com. We HAD a jumper and climber, but by changing his diet and removing as many toxins as we could, he doesn't do these things any more :-)
Blessings to you,
