What we do.

Lately you've been seeing a lot of congratulations posts about completions of levels and books. In our homeschool, what we do when someone finishes a level, or meets a goal, or completes a unit or something like that, is that I print out a certificate and then we hang them on the child's bedroom door to celebrate their accomplishment.

There are many websites where you can print out some custom certificates. Here are my favorites:
http://www.freeprintablecertificates.net/
http://www.aaacertificates.com/free.php
http://www.dltk-cards.com/award/
http://www.bannersandawards.com/awards/awards.html
http://www.123certificates.com/
http://www.certificatemaker.com/

One of the nice things about doing things this way, is that I can put the certificate of completion in the portfolio of the kid, and so it acts as a record of their progress.
