This is common at this level. Students recognize individual affixes but haven't yet internalized that the same root (in this case, 'struct,' meaning build) can pair with different prefixes and suffixes to create a whole family of related words. Help by building word families visually: write the root 'struct' in the center, then branch outward with words built from it (con-struct, in-struct, de-struct, etc.). Point out that the root's meaning (build) stays constant; the affixes add nuance. This visual approach helps cement the pattern.
These suffixes have the same meaning (both create nouns indicating an action or state) and are often pronounced identically, so the confusion is understandable. Rather than teaching them as separate rules, teach them as phonetic variants of the same suffix. When students see a word like 'comprehension,' explain that '-sion' appears after certain letter combinations (like 'hend'). Provide a simple rule: '-tion' is more common overall; '-sion' typically follows 'd' or 's' sounds. For this worksheet, focus on meaning over spelling variation—both '-tion' and '-sion' indicate 'the act or result of.'
A base word is a complete word that can stand alone and have affixes added to it (like 'play' in 'replay'). A root is the core of a word, often from Greek or Latin, that typically cannot stand alone in English (like 'struct' from Latin, found in construct, structure, instruct). This worksheet emphasizes roots because mastering Greek and Latin roots is crucial for accessing academic vocabulary in middle school. Understanding that 'struct' is a root, not a base word, helps students recognize it in words like 'infrastructure' or 'restructure' even when it's buried in the middle of longer words.

This is a sophisticated distinction that challenges many 6th graders. The key is whether removing the beginning portion leaves a recognizable word or root. For example, in 'unhappy,' removing 'un-' leaves 'happy,' a real word. So 'un-' is a prefix. But in 'under,' removing 'un-' leaves 'der,' which isn't a word on its own—'under' is a base word, not a prefix plus root. Similarly, 'receive' begins with 're-,' but removing it leaves 'ceive,' which isn't a standalone word. In this case, 're-' isn't a prefix; 'receive' is a whole word where 're-' happens to be the beginning. When in doubt, check: does the remaining part make sense as a word or recognizable root?
Earlier grades typically focus on common, transparent prefixes and suffixes (like 're-,' un-,' and '-ing'), where the affixes are easy to spot and separate. This advanced worksheet combines multiple affixes in single words, introduces Greek and Latin roots that don't look like typical affixes, and includes academic vocabulary your student may have never encountered. Words like 'multidisciplinary,' 'irreconcilable,' or 'physiotherapy' require students to recognize and manipulate multiple layers of meaning. It's 'hard' because it demands pattern recognition, deep understanding of how roots combine, and the ability to apply morphological knowledge to genuinely new and complex words—skills that go well beyond basic prefix-suffix identification.
