Which Wedge?

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!

What you'll need:

variety of tools

cutting board

block of cheese

safety goggles 
(The mice have them!)

1

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.

3

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.

4

A kitchen knife seems to be the answer!

5

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