Know Roots and Inflections - 1st Grade Writing

1. Look at these words. Which words belong to the word family for cook?
   Answer: cook, cooked, cooking Cook, cooked, and cooking are correct because they are all forms of the word cook with different endings. Cooks, books, and looks mix in words that are not related to cook. Cookie, cooker, and cooking put in some unrelated words along with one true form. Cooked, cleaning, and helping mix in words that do not belong to the cook family.

3. Look at these words: jump, jumps, jumped, jumping. Which is the root word?
   Answer: jump We're finding the root word. The root word is the simplest form. Jump is the root because it has no endings.

5. Look at these words: walk, walks, walked, walking. Which is the root word?
   Answer: walk We're looking for the root word. Walk is the root word. It's the simplest form without any endings.
6. Look at these words. Which word is an ending form of the root word clean?
   Answer: cleaning This question aligns with CCSS.L.1.4.c, which focuses on identifying frequently occurring root words and their inflectional forms. A root word (or base word) is the main word before any endings are added, and inflectional forms are versions of the same word with endings like -s, -ed, or -ing added; for example, 'look' is the root word, and 'looks,' 'looked,' and 'looking' are its inflectional forms—they're all forms of the same word 'look' with different endings. In this stimulus, the task is to identify an inflectional form (or 'ending form') of the root 'clean' from the choices, where 'cleaning' is the form with the -ing ending. The correct answer, 'cleaning' (B), works because it is an inflection of 'clean,' adding -ing while keeping the same root and meaning. Distractors like 'clan,' 'clear,' and 'clown' fail as they are unrelated words with different roots and meanings, not inflections of 'clean.' To teach, practice adding endings to roots like 'clean' to form 'cleans,' 'cleaned,' 'cleaning.' Use word sorts to distinguish families, watching for confusions between similar-sounding but different roots.
7. These words come from the same root word: play, plays, played, playing. Which is the root word?
   Answer: play We need the root word here. The root word is the base word. 'Play' is the root before adding endings.
8. These words come from the same root word: help, helps, helped, helping. Which word is the root word?
   Answer: help We're finding the root word in this family. Help is the root word. Helps, helped, and helping all have endings added.
9. Look at these words: help, helps, helped, helping. Which is the root word?
   Answer: help This question aligns with CCSS.L.1.4.c, which focuses on identifying frequently occurring root words and their inflectional forms. A root word (or base word) is the main word before any endings are added, and inflectional forms are versions of the same word with endings like -s, -ed, or -ing added; for example, 'look' is the root word, and 'looks,' 'looked,' and 'looking' are its inflectional forms—they're all forms of the same word 'look' with different endings. The root word stays the same; we just add endings to show different times (looked = past) or different uses (looks = he/she looks, looking = right now), and word families share the same root. In this stimulus, the root word is 'help' and the inflections are 'helps' (with -s), 'helped' (with -ed), and 'helping' (with -ing). 'Help' is the root word because it's the base form before any endings, and the other words (helps, helped, helping) are all forms of 'help' with endings added. A common distractor like 'helped' fails because it is an inflection (it has the -ed ending), not the root word—the root is 'help' without any endings. To help students, teach them to identify roots by covering the ending: for 'helps,' cover '-s' to see 'help' as the root; practice common endings like -s, -ed, -ing, and use word sorts to group families by root, watching for mixing different word families or choosing inflections as roots.
10. Look at these words: cook, cooked, cooking. Which is the root word?
    Answer: cook The correct answer is cook because it is the base word found inside cooked and cooking. Cookie is incorrect because it is a different word entirely, not a form of cook. Cooking is incorrect because it has an added ing. Cooked is incorrect because it has an added ed.
11. Read the word family. What is the root word in talks, talked, talking?
    Answer: talk This question aligns with CCSS.L.1.4.c, which focuses on identifying frequently occurring root words and their inflectional forms. A root word (or base word) is the main word before any endings are added, and inflectional forms are versions of the same word with endings like -s, -ed, or -ing added; for example, 'look' is the root word, and 'looks,' 'looked,' and 'looking' are its inflectional forms—they're all forms of the same word 'look' with different endings. In this stimulus, the word family includes talks, talked, and talking, where 'talk' is the root word, and the inflections are 'talks' (with -s), 'talked' (with -ed), and 'talking' (with -ing). The correct answer, 'talk' (A), works because it is the base form without endings, and the listed words are all inflections derived from 'talk.' Distractors like 'talked,' 'talking,' and 'tall' fail; 'talked' and 'talking' are inflected forms, not the root, while 'tall' is a different word with a separate root and meaning. Teach by covering endings, such as '-ed' in 'talked' to reveal 'talk.' Practice with word families and sorts, addressing errors like confusing similar-sounding words (e.g., 'talk' vs. 'tall') or selecting inflections as roots.
12. Look at these words: play, plays, played, playing. Which word is the root word?
    Answer: play This question aligns with CCSS.L.1.4.c, which focuses on identifying frequently occurring root words and their inflectional forms. A root word (or base word) is the main word before any endings are added, and inflectional forms are versions of the same word with endings like -s, -ed, or -ing added; for example, 'look' is the root word, and 'looks,' 'looked,' and 'looking' are its inflectional forms—they're all forms of the same word 'look' with different endings. The root word stays the same; we just add endings to show different times (looked = past) or different uses (looks = he/she looks, looking = right now), and word families share the same root. In this stimulus, the root word is 'play' and the inflections are 'plays' (with -s), 'played' (with -ed), and 'playing' (with -ing). 'Play' is the root word because it's the base form before any endings, and the other words (plays, played, playing) are all forms of 'play' with endings added. A common distractor like 'played' fails because it is an inflection (it has the -ed ending), not the root word—the root is 'play' without any endings. To help students, teach them to identify roots by covering the ending: for 'plays,' cover '-s' to see 'play' as the root; practice common endings like -s, -ed, -ing, and use word sorts to group families by root, watching for students who group by endings instead of roots or confuse similar roots.
13. Look at these words. Which words belong to the word family for play?

Plays, plan, and plate mix in words that are not related to play. Playing, looking, and walking put play with words that do not belong in its family. Played, player, and replay also mix in forms that go beyond simple endings.
14. Look at these words: cat, cats, cap, cut. Which word is the root word for cats?

15. Read the word family: look, looks, looked, looking. Which is the root word?
    Answer: look We're finding the root word. The root word is the simplest form. 'Look' is the root because it has no endings.
16. Look at these words: cat, cats. Which word is the root word?
    Answer: cat Cat is the root word because it is the small word that cats is built from by adding an ending. Cut and cap are different words that do not relate to cat or cats at all. Cats has an ending added to show there is more than one.

18. Look at these words. Which words are forms of the root word cook?
    Answer: cook, cooked, cooking This question aligns with CCSS.L.1.4.c, which focuses on identifying frequently occurring root words and their inflectional forms. A root word (or base word) is the main word before any endings are added, and inflectional forms are versions of the same word with endings like -s, -ed, or -ing added; for example, 'look' is the root word, and 'looks,' 'looked,' and 'looking' are its inflectional forms—they're all forms of the same word 'look' with different endings. In this stimulus, the task is to identify which group consists of forms of the root 'cook,' and option A lists 'cook' (root), 'cooked' (with -ed), and 'cooking' (with -ing), all sharing the same root. The correct answer, A, works because these are the root and its inflections, with endings added to 'cook' for different tenses. Distractors fail by mixing unrelated words, like B with 'cookie' and 'cooker' (derivational), C with different roots like 'book' and 'look,' or D with words from other families. Teach word sorts to group by roots, and practice adding endings to 'cook.' Watch for errors like grouping by sounds or including non-inflectional forms.

    Answer: help We're finding the root word. Root words have no endings. 'Help' is the root without -s, -ed, or -ing.
