How many roots should a seventh grader know?

Somewhere between twenty and forty, learned in families rather than as a list. Each one unlocks several words, so forty roots is worth several hundred words of reading vocabulary.

Why do all three choices look so similar on these items?

Because if the options came from different families, a student could answer from topic alone. Building every choice from the same root forces them to use the sentence's meaning, which is the actual skill.

Is this the same as prefixes and suffixes?

Related but not the same. A prefix or suffix attaches to a word; a root is the piece the word is built around. Most academic words carry all three, which is why word study gets easier once roots are in place.

A root is the core of a word, and most academic English is built from Greek and Latin ones. Knowing that cred means believe or that spec means look unlocks whole families of words at once. Seventh graders choose the word a sentence needs from a family that shares one root.

How to teach this

Teach roots in families and always with three or four words attached, because a root in isolation is a fact and a root with a family is a tool. Cred gives credible, incredible, credit, and credential; spec gives inspect, perspective, spectator, and suspect. When your student meets an unfamiliar word in reading, the question to ask is not what does this mean but what does it look like. The roots that pay off fastest at this age are the ones that turn up in science and social studies: chron, hydr, therm, cracy, anthro, and terr.

Watch for: A root isn't a prefix; it's the core of the word. Prefixes and suffixes attach to it (in-spect-ion). Knowing one root unlocks a family of words, not just one: port gives transport, export, import, and portable.
