I can't seem to remember to cancel when I multiply mixed numbers! How can I remember it?

I missed a question on a math test because I can't remember to cancel when I multiply mixed numbers! I need an idea on how to drill that into my brain so that mistake won't make me miss a question again.

Question applies to ages: 11, 12, 13

The phrase is "Cheaters Make Me Crazy." The first letters of those words are C M M C, which stand for the four steps in the process:

Change mixed numbers to fractions
Multiply the numerators
Multiply the denominators
Cancel

Some teacher will use the phrase "Cheese Makes Mice Run," with the first three letters C M M being the same as above, and the last letter, "R," standing for "Reduce and simplify," which my son says is the same as "cancel."

So, if you can remember either "Cheaters Make Me Crazy," or "Cheese Makes Mice Run," you'll have all the steps drilled into your brain and you won't forget to cancel.

Hope this helps.
