Also Long Ago

Once upon a time there was a boy who is not so little anymore.  In kindergarten he built a roller coaster from K-Nex.  Today, as a fourth grader, he built a cool "beehive" using Contraptions.

 

 

A Long, Long Time Ago

A long, long time ago a group of first graders built the "tallest marble run EVER."  Those first graders grew-up and are now fifth graders.  One from the old group and a few new kids built the new "tallest marble run EVER."  I enjoy watching the drop-ins at moments like this!
