	Digging in Mock Rock Mock rock is pretend rock (kind of like play dough, but with sand in it). We make mock rock, bury polished rocks in it, then dig out the polished rocks. Go here to learn how to make mock rock.

Polished Rock Bingo

We played Polished Rock Bingo at Ethan's
birthday party this year. To see an online
version of a Polished Rock Bingo game card,
go here.

To download a Word 2000 version of the
Bingo card, click here. WARNING: This is
a really big file! The advantage of using this
version is that you can rearrange the pictures
to make as many different bingo cards as
you need.

To download an Adobe Acrobat pdf version
of the Bingo card, click here. This is much
smaller than the Word 2000 file, but you can
only print one card at this point. (I'll change
that in the future!)
