My grandaughter made her first quilt at 5 years (a teen now and no time to sew). Grand boys( 9 and 11) built a wood walkway a couple of years ago. Its not straight or level by any means but I love it. They measured, sawed, drilled and nailed while I sat in chair and "suppervised. Older grand boys built a split rail fence at 8 and 10. It took them awhile to figure out where to dig the next post hole so the rails fit but finished it. It still stands along my drive. Loved teaching them all how to do things. When mine were small there just was not enough time to do more than chores (we farmed and raised beef cattle). They learned responsibility without knowing it and became proficient mechanics in repairing equipment. Things that have taken them far in their adult lives.
