How do you teach the prefix circum-?

Circum- is a narrow prefix with only a handful of school words, but one of them matters a lot: circumference, which every student meets in grade 7 math. Teach it there. Draw a circle, trace the edge with your finger, and say that circum means around. The rest of the word (fer, carry) tells you the line carries all the way around. Circumnavigate is the next easiest, because navigate is familiar.

A quick routine

Draw a circle on the board and trace it while you say, "Circum means around." Show circumference, circumnavigate and circumpolar. For each, the student points to what goes around: the edge of the circle, the ship, the stars near the pole. Then ask, "What would it mean to circumnavigate the school?" A good answer walks the whole outside wall.

What do students mix up with circum-?

Circle and circus come from the same old word for ring, so they feel related, and they are. But they are not built with the prefix circum. Keep the two apart for spelling: circle has no m. Circumstance is the hard one, because the around meaning is hidden. It means the facts standing around an event.

Some of these words change spelling where the parts join. The spelling rules pages cover dropping e, doubling and changing y to i. For the sounds inside these words, see the phonics word lists.
