L.1.4

Determine or clarify the meaning of unknown and multiple-meaning words and phrases based on grade 1 reading and content, choosing flexibly from an array of strategies.

Objective

Students will be able to work out a word's meaning from the sentence around it or from its root and ending, and say which way they used.

Students are successful when they can

  • Reads the whole sentence before guessing, and gives a meaning that fits it: "soggy" in "My sock fell in the bath and came out soggy" means very wet.
  • Covers an ending to find the root: "jumping" — cover -ing, read "jump."
  • Says which way they used: "I used the sentence" or "I used the parts."

What you need

  • Five sentence strips, each with one bold word (listed in the Teach and guided practice)
  • Ending cards: -s, -ed, -ing, and a sticky note for covering
  • The printable practice sheet linked at the end of this plan

The lesson

Warm-up — cover the ending

5 min
  1. Write three words: "jumping," "kicked," "hats."
  2. Cover the ending of "jumping" with a sticky note. The class reads "jump." Uncover it: "jumping." Ask what -ing tells us. Fish for: "It is happening now."
  3. Do the same with "kicked" (-ed means it already happened) and "hats" (-s means more than one).
  4. Say: "The little word inside is called the root. The ending changes it a little bit, but not a lot."
“When a word looks long, cover the end. There is often a word you know hiding inside.”

Teach — two ways in

13 min
  1. Write: "My sock fell in the bath and came out soggy." Point at "soggy." Say: "I do not know this word. I am not going to guess from the s. I am going to read the whole sentence."
  2. Read it aloud. Think aloud: "It fell in the bath. What happens to a sock in a bath? It gets wet. So soggy must mean wet — really, really wet."
  3. Check it: put "very wet" in its place and read the sentence again. It still makes sense. That is how we know.
  4. Now write: "The puppy was resting in its bed." Point at "resting." Say: "This time the parts help." Cover -ing. Read "rest." Ask what rest means. Fish for "having a sleep or a sit-down." Uncover: resting means having a rest right now.
  5. Hold up two cards: "Use the sentence" and "Use the parts." Ask which one we used for soggy and which for resting.
  6. Do one more with the class choosing the card: "The ducks splashed in the puddle." Cover -ed: "splash." Both cards help here — the sentence says puddle, the root says splash.
“Read the whole sentence first. The word is not alone on the page — the other words are there to help it.”

Guided practice — four words

12 min
  1. Give pairs four strips: "The cake was so tiny it fit in my hand." / "The boys were painting the fence." / "The kitten was frightened of the loud bang and hid." / "She opened the gift and gasped."
  2. For each bold word (tiny, painting, frightened, gasped) they write or say a meaning and hold up the card they used.
  3. Tiny and frightened need the sentence; painting needs the parts; gasped can use either. Do not tell them this in advance.
  4. Ask one pair for frightened: "What told you?" The answer to look for: "loud bang and it hid — so it means scared."
  5. Take feedback: which was harder, and why? Most will say frightened, because the root "fright" is not a word they know well.
“Show me your card. Now prove it — which other words in the sentence helped you?”

Independent practice

8 min
  1. Students complete the word-meaning page: circling the meaning that fits each sentence, then splitting words into root and ending.
  2. Remind them to read the whole sentence aloud in a whisper before circling.
  3. Watch for children who circle by the first letter; ask them to read the sentence to you before they choose.

Close

2 min
  1. Write: "The baby was sleepy after her bath, so she yawned." Ask what sleepy means and which way they worked it out.
  2. Fish for both: the root is "sleep," and the sentence says she yawned.

What goes wrong, and why

Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.

Guesses from the first letter: reads "soggy" and says it means "soft" or "sorry."

Why: The first letter is the part they can decode quickly, and a word starting with the same sound feels like a good match. They are treating meaning as a sound puzzle.

Fix: Cover the hard word completely and read the sentence with a "mmm" in the gap. Ask "What would make sense here?" The guess must come from the sentence before they look at the letters.

Splits a word where there is no ending: "cat" inside "catch," or "be" inside "bed."

Why: Finding a little word inside was praised, so they look for any little word, whether or not the leftover letters are a real ending.

Fix: Check the leftover. After you cover the root, is what is left -s, -ed or -ing? In "catch," "ch" is not an ending, so it is not cat plus something. Keep the three ending cards on the desk to compare.

Uses only one strategy for every word, even when it does not help.

Why: The first strategy they learned has become the whole toolkit, and nothing makes them stop and choose.

Fix: Make them name the strategy before they answer: hold up a card first, then explain. Once choosing is a visible step, the other card becomes an option.

If they are not there yet

  • Offer two meanings to choose between for each word: "Does soggy mean very wet or very dry?"
  • Use only words whose roots the child can already read: jumping, kicked, hats, played.
  • Read each sentence to the child first, so their effort goes into the meaning, not the decoding.

If they finish early

  • Add "un-" to three words — happy, kind, lock — and say what un- does each time.
  • Find a word where the parts trick you: "butter" is not "butt" plus -er. Explain how you know.
  • Write your own sentence that would help a friend work out the word "gigantic."

Exit ticket

"The cat was hungry, so it gobbled its food." What does "gobbled" mean? Which way did you use?

What to look for: "Ate it fast" with "I used the sentence — it was hungry." A meaning with no strategy may be a lucky guess: ask them to show you. "Gobbled means goblin" means they are matching sounds and need the cover-the-word move again.

Questions about Working Out a New Word

How long does the Working Out a New Word lesson take?

40 minutes, split across 5 timed sections: warm-up 5 min, teach 13 min, guided practice 12 min, independent practice 8 min, close 2 min. The minutes are stated per section and add up to the stated length, so the plan can be cut or extended at a section boundary rather than abandoned halfway.

Which standard does Working Out a New Word teach?

CCSS.ELA-LITERACY.L.1.4 — L.1.4, Language for Grade 1: “Determine or clarify the meaning of unknown and multiple-meaning words and phrases based on grade 1 reading and content, choosing flexibly from an array of strategies.” In plain terms, work out a new word from the sentence around it or from its parts.

What do I need to teach this lesson?

Five sentence strips, each with one bold word (listed in the Teach and guided practice), ending cards: -s, -ed, -ing, and a sticky note for covering and the printable practice sheet linked at the end of this plan. Everything listed is either ordinary classroom equipment or a free printable from this site — there is nothing to buy and nothing to prepare beyond photocopying.

What mistakes should I expect in this lesson?

Three, each a reasoning error rather than carelessness: guesses from the first letter: reads "soggy" and says it means "soft" or "sorry."; splits a word where there is no ending: "cat" inside "catch," or "be" inside "bed." and uses only one strategy for every word, even when it does not help. The plan gives the thinking behind each one and the teaching move that addresses the thinking rather than the symptom.

How do I know whether the lesson worked?

The exit ticket asks: “"The cat was hungry, so it gobbled its food." What does "gobbled" mean? Which way did you use?.” "Ate it fast" with "I used the sentence — it was hungry." A meaning with no strategy may be a lucky guess: ask them to show you. "Gobbled means goblin" means they are matching sounds and need the cover-the-word move again. That tells you whether the class needs a reteach or a thirty-second conversation before you plan tomorrow.

Is there a worksheet to go with Working Out a New Word?

Yes — 1 printable L.1.4 worksheet, linked at the end of the plan and free like the rest of the site. Each one comes with an answer key and 25 versions, so the practice after the lesson can be a different paper on every desk.

Is Working Out a New Word free to use?

Yes. The plan, its printables and their answer keys are free to read, print and photocopy for your own class, with no account and no email capture. It was last reviewed on October 8, 2026. Please do not resell it or republish it as your own.
