I picked this baby up oh about 5 years ago at a Scholastic Book Fair when my youngest son was in still in elementary school. (How much do I love Scholastic Book Fairs? Even more now that they've picked up DON'T FEED THE BOY. Look for it!)
I didn't know at the time that I would be writing poems for kids -- I just thought it was a fun thing to have around the house. :)
Now, it's my go-to source when I'm working on a poem for kids, even though I'm not really into writing rhymed-n-metered verse. Oh, the joys of internal rhyme! And sure, you can find rhyming dictionaries online. But this one is so easy to use.
What's your secret weapon?
