This question tests using root words as clues to meaning (CCSS.L.3.4.c). The root word is 'teach' which means to show how. The unknown word 'teaching' contains this root, so we can use what we know about 'teach' to figure out 'teaching'. A root word is the main part of a word that carries the basic meaning. Words that share the same root are related in meaning. When you know one word in a word family, you can use that knowledge to understand other words with the same root. For example, if you know 'friend' means a person you like and trust, you can figure out that 'friendly' means acting like a friend. The word 'teaching' breaks into parts: teach + ing. The root 'teach' means to show how which we know from 'teach'. The suffix 'ing' means the act of doing something. Putting these together: to show how + the act of = the act of showing how. Choice A is correct because it properly uses the root meaning and the suffix. Since 'teach' means to show how, and 'ing' means the act of, 'teaching' means the act of showing how. This shows the connection between words in the same family. Choice C is incorrect because it gives an unrelated definition that misapplies the suffix or confuses with a different word. Students make this error when they misapply the suffix meaning or guess without using root knowledge. To help students: Teach common root word families together (friend-friendly-friendship, help-helper-helpful, teach-teacher-teaching). Strategy for unknown words: (1) Look for root you recognize. (2) Remember what that root means from word you know. (3) Look at any prefixes or suffixes. (4) Combine root meaning + affix meanings. Practice with word family charts showing how root appears in multiple related words. Examples: care (concern) → careful (full of concern) → careless (without concern) → caring (showing concern). Watch for: not recognizing shared roots / ignoring how affixes change meaning / treating every unknown word as completely new.
