We are studying ponds currently in our first grades, so this fits right in! I read a book about ponds and we've read a number of books and articles about frogs. Did you know that frogs have teeth? Toads don't, though.
So - my poem for frogs
A Tongue Twister poem is made up of lines/verses that are hard to say when read aloud by using similar consonant sounds in succession (use of alliteration). In other words, the poem ties your tongue into knots. This form does not require end or internal rhyme.
Funny 'phibian family of
On four foot long logs in a fog
With fascinating flopping flippers
For fine fitting freshwater slippers
Feasting on freshest flitting fluttering fly-bys
Faithful friends, not fearsome foes
