Tongue Twisters

I made a page of different tongue twisters to introduce the idea, then I've compiled a few different tongue twisters together into one poem, intended to be read all at once. There are 9 different bits to it.

I'd say introduce the first document in one class to introduce the diea, then the poem in the next.

In my school's English club, we're timing ourselves to see how fast we can say it as a group, each student taking two lines.
