Merry and I are having a chat over on the Scratch Pad about misuses of verbs. She did some research and came up with some fun sites to help you and your kids sort things out.
Irregular verbs links
Well, I found this interesting link–here 1 or 2 people can play a jeopardy-like game on the computer, they have to be able to type the correct word to fill in the blank. http://www.quia.com/cb/8111.html That’s a fun idea I might be able to do with my kids on our own, hm…
This site has quizes & a crossword puzzle etc… http://grammar.ccc.commnet.edu/grammar/cgi-shl/par2_quiz.pl/irregular_quiz.htm

It has a series of quizes you can do online or print (pretty basic drill-type things though). They’d be more fun adapted into a Jeopardy format, LOL!
