My boys have loved some of the following things in their free-time through the years:
1. paper airplane folding kits (especially The Klutz Paper Airplane Book)
2. oragami kits (the page-a-day calendar one was good)
3. Yo-yo kits (Barnes and Noble)
4. Flip Book kits (from Klutz I think)
5. Window Art (from Klutz)
6. Magic Trick kits (from Target)
7. card trick, coin trick, and rope tricks kits
8. juggling set
9. puppet theater (kiddos continually make their own puppets out of socks/paper/craft stick puppets etc.)
10. latchhooking kits (we start out with a small colorful one at first)
11. colored Crayola Model Magic clay to make very small seasonal scenes to set on dresser/windowsill/counters etc. as gifts for others
12. a tape recorder or cd recorder with small microphone to record books on tape/CD (they take turns reading the parts of a selected book and making background noises)
13. kid's cookbook for trying new recipes once-a-week (Better Homes and Gardens New Junior Cook Book)
14. Erector Sets (Build and Play by Meccano is the junior version of this)
15. blank hardback book from Miller Pads and Paper for each child (They write their stories in this to keep them in one place - my boys LOVE this! After they've written the stories in long-hand first, they are allowed to type them in word and add photos. They make typed copies of their books to give to the relatives at a 4th of July celebration my boys put on each year.)
16. Legos (all put together in one huge tub with all direction sets in there too)
17. K'nex (all put together in one huge tub with directions too)
18. shadow theater (from Barnes and Noble)
19. Board Games: Axis and Allies, Risk,Stratego, Monopoly, Sorry, Memoir '44, Zooreka
20. Card Games: Loot, Sleeping Queens, Squandron Scramble, Uno Spin
21. Audio Books
Anyway, this is all of can think of now. This list would be for my older boys 10+ and also includes my 7 year old in much of it. My 3 year old has his own separate things that he loves to do. Maybe this will get the thoughts flowing.
Blessings,
