Part of building a project is to be able to choose the right kind of lumber. Lumber actually has different grades for appearance or strength. I came across a neat site that parents could use to help teach their children about lumber. 

 

Start HERE to learn about things to look for in lumber and to understand how it is graded.

 

Then go to THEIR PAGE filled with terms and definitions that everyone, but especially our boys, need to know before they start buying lumber.
