There are all kinds of wedges, but not
every wedge is useful for specific
jobs. For instance, an axe was
better than a saw for cutting
wood, even though the
teeth of a saw are wedges.
These mice need to divide
a big block of cheese.
Which wedge would
be best to use? You
can try this, too!

The goal is to split the cheese into slices.
2
The mice try splitting the cheese with a kitchen whisk.
Hmmmm… That didn’t work so well.

The mice know that the tines on a fork are wedges, so they try a fork next. Stabbing the cheese with a fork doesn’t really work, either.

A kitchen knife seems to be the answer!

Now all the mice have a slice of cheese. Which wedge worked best for you?
