L.1.6

Use words and phrases acquired through conversations, reading and being read to, and responding to texts, including using frequently occurring conjunctions to signal simple relationships (e.g., because).

Objective

Students will be able to use a new word in a sentence of their own that shows what it means, and join two ideas with "because," "but" or "so."

Students are successful when they can

  • Writes a sentence that would not make sense if the new word were swapped for another: "The enormous elephant could not fit through the door."
  • Uses "because" to give a reason: "I was grumpy because I lost my hat."
  • Chooses "but" when the second idea goes against the first: "I wanted to play, but it was raining."

What you need

  • Five words from the class word wall: enormous, grumpy, gently, peek, crowded
  • Joining word cards: and, but, so, because
  • The printable practice sheet linked at the end of this plan

The lesson

Warm-up — five from the wall

5 min
  1. Point to five wall words one at a time: enormous, grumpy, gently, peek, crowded.
  2. For each, ask "Where did we meet this word?" and "Show me with your face or hands." Grumpy gets a frown; peek gets hands over eyes with a gap.
  3. Say: "Knowing a word means you can use it in your own sentence, not just say it."

Teach — a sentence that proves it

13 min
  1. Write: "The enormous thing was there." Ask: "Does this sentence show me you know what enormous means?"
  2. Do the swap test. Cross out enormous and write "tiny": "The tiny thing was there." It still works. So the first sentence proved nothing.
  3. Write a better one: "The enormous elephant could not fit through the door." Swap in "tiny": "The tiny elephant could not fit through the door." Now it sounds silly — so the sentence proves the meaning.
  4. Now hold up "because." Write: "Max was grumpy." Ask: "Why?" Add: "Max was grumpy because his ice cream fell on the floor." Say: because tells us the reason.
  5. Hold up "but." Write: "I wanted to peek at my present, but Mom said to wait." Say: but means something gets in the way.
  6. Hold up "so." Write: "The bus was crowded, so we stood up." Ask what so tells us. Fish for "what happened next because of it."
“Write a sentence I could not write unless I knew what the word means. If I can swap the word out and it still works, try again.”

Guided practice — two words, two joins

12 min
  1. Each child chooses two wall words and says a sentence for each to a partner before writing anything.
  2. The partner does the swap test aloud: they say the sentence with "tiny" or "happy" instead and decide whether it still works.
  3. Each child writes their two sentences. One of them must use a joining-word card.
  4. Circulate with one question: "Which word in your sentence proves the meaning?" For "I tiptoed gently so the baby would not wake," the answer is "baby would not wake."
  5. Read two good sentences aloud to the class and say what makes them good.
“Tell your partner your sentence first. If it passes the swap test out loud, it is ready to write.”

Independent practice

8 min
  1. Students complete the new-words page: matching each word to its meaning and choosing the right joining word.
  2. Children who finish write one more sentence with a wall word and "because."
  3. Sit with anyone using "and" in every gap and ask: "Is this a reason, a but, or just more?"

Close

2 min
  1. Read two sentences: "The room was crowded." and "The room was so crowded that I could not find a chair." Ask which proves the meaning.
  2. Fish for the second, "because it says there was no space."

What goes wrong, and why

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

Writes a sentence the word could be swapped out of: "I saw a grumpy dog."

Why: They used the word and the sentence is correct, which is what they heard the task ask for. They do not yet see that a sentence can be correct and still show nothing.

Fix: Run the swap test on their sentence with them: "I saw a happy dog." Ask what would show us the dog was grumpy. Help them add the evidence: "The grumpy dog growled at everyone."

Joins everything with "and": "I was cold and I put my coat on and I went out."

Why: "And" joins anything to anything and never sounds wrong, so it is the safe choice. They have not had to think about how two ideas are related.

Fix: Ask about the link: "Did you put your coat on because you were cold?" Offer the cards and let them choose: "I was cold, so I put my coat on." Read both aloud and ask which tells us more.

Copies the sentence the word came from in the book: "The enormous giant stomped."

Why: That sentence is known to be right, and using it feels safe. Copying is a reasonable way to avoid being wrong.

Fix: Ask for a sentence about their own life: "When have you seen something enormous?" Moving the word to a new place is what shows it has been learned.

If they are not there yet

  • Work with one word only, and give a sentence starter: "The enormous ___ could not ___."
  • Use picture prompts: a photo of a crowded bus to talk about before writing about crowded.
  • Offer just two joining words, "because" and "but," with a picture on each card.

If they finish early

  • Use two wall words in one sentence that proves both: "The grumpy giant gently put the kitten down."
  • Write the same pair of ideas with "so" and with "because" — "It rained, so we stayed in" and "We stayed in because it rained" — and say what changed.
  • Bring a new word from home or a book, write a sentence that proves it, and add it to the wall.

Exit ticket

Choose a word from the wall. Write a sentence that shows you know what it means. Use "because" or "but."

What to look for: A sentence that fails the swap test, such as "I peeked through the curtain because I wanted to see the snow." A sentence that still works with any word swapped in means the swap test needs showing again. "And" instead of the asked joining word means more work on reasons.

Questions about Using New Words in Your Own Sentences

How long does the Using New Words in Your Own Sentences 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 Using New Words in Your Own Sentences teach?

CCSS.ELA-LITERACY.L.1.6 — L.1.6, Language for Grade 1: “Use words and phrases acquired through conversations, reading and being read to, and responding to texts, including using frequently occurring conjunctions to signal simple relationships (e.g., because).” In plain terms, use new words in your own writing, including joining words like because.

What do I need to teach this lesson?

Five words from the class word wall: enormous, grumpy, gently, peek, crowded, joining word cards: and, but, so, because 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: writes a sentence the word could be swapped out of: "I saw a grumpy dog."; joins everything with "and": "I was cold and I put my coat on and I went out." and copies the sentence the word came from in the book: "The enormous giant stomped.". 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: “Choose a word from the wall. Write a sentence that shows you know what it means. Use "because" or "but.".” A sentence that fails the swap test, such as "I peeked through the curtain because I wanted to see the snow." A sentence that still works with any word swapped in means the swap test needs showing again. "And" instead of the asked joining word means more work on reasons. 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 Using New Words in Your Own Sentences?

Yes — 1 printable L.1.6 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 Using New Words in Your Own Sentences 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.
