MCT theme hook
You've written letters to people you chose — each sentence stood alone. Today we discover the words that join two ideas into one sentence, making your letter flow instead of feeling choppy.
PWP progress check-in
In your letter, conjunctions will join your ideas so two thoughts can live in one sentence — that's the joining-and-placing work you're building toward.
Steps
- Have students silently read one sentence from their in-progress letter — any sentence. Ask: 'What if we wanted to add one more idea to that sentence without starting a new sentence?'
- Display two short sentences on the board: 'Emily laughed. Roberto laughed.' Ask: 'I used to think we needed two sentences for two people. What word could join them?' Wait for student noticing before naming 'and' as the joining word.
- Write 'Emily and Roberto laughed' on the board. Ask: 'Now I think one sentence can hold two ideas. What changed? What's the glue word doing?'
- Pose the provocation from the source map: 'These two short thoughts feel choppy; what word joins them, and what word tells us where?' Let students wonder before you name conjunctions and prepositions in the Workshop.

Two short sentences from Sentence Island Chapter Two that demonstrate joining with a conjunction. Read the choppy version first, then the joined version, so students hear the difference before naming the pattern.
Entry point: Read each version aloud once — the choppy pair first, then the joined sentence — before asking students what changed.
Comprehension prompts
- What's the difference between the two versions — what do you hear?
- Which version feels smoother to your ear, and why?
Discussion prompts
- When might you want two short sentences instead of one joined sentence?

Conjunctions are the glue words that join two nouns, two verbs, two adjectives, or two adverbs into a compound. The seven coordinating conjunctions (and, but, or, nor, for, so, yet) are the most common; they join words or groups of words of the same kind.
Suggested exercises
Application: Students write three pairs of short sentences about their letter recipient, then join each pair with 'and' or 'but' or 'or'. Example: 'My Future Self will be taller. My Future Self will be older.' becomes 'My Future Self will be taller and older.'
Extension: For faster students, ask them to join three ideas with two conjunctions in one sentence. For slower students, provide sentence frames: '[Noun] is [adjective] and [adjective].' or '[Noun] [verb] and [verb].'
Application: Display five sentences from Grammar Island page 87 on the board. Students identify what KIND of words the conjunction joins in each sentence — two nouns, two verbs, two adjectives, or two adverbs. They label each pair.
Extension: For faster students, ask them to write one sentence where the conjunction joins two verbs and one where it joins two adjectives. For slower students, give them two sentences to analyze instead of five.
Application: Ask students: 'Grammar Island says conjunctions hate to join things that are different. Why would a conjunction not want to join a noun to an adjective?' Let students puzzle for 30 seconds, then discuss in pairs before sharing with the room.
Extension: For faster students, ask them to try writing a sentence that breaks the rule and explain why it sounds wrong. For slower students, give them two example sentences — one that follows the rule, one that breaks it — and ask which one sounds right.
How the secondary supports the primary: The Preposition unit extends the Conjunction unit by adding the placing function to the joining function — together they let students write sentences that hold two ideas joined in time or space.
Prepositions show how two things are related in time, space, or other ways. Each preposition begins a prepositional phrase (the preposition plus the noun or pronoun at the end, called the object). Common prepositions include on, in, under, before, after, from, for.
Synergy: Grammar Island's Preposition unit pairs with Conjunction in one Foundation Workshop because joining and placing are the two moves that let a sentence hold complexity — conjunctions join ideas, prepositions place them in time or space.
Suggested exercises (secondary)
Application: Students write three sentences about where their letter recipient is or when they'll read the letter, using a different preposition in each sentence. Example: 'My Future Self will read this letter in five years. The letter will sit on my shelf until then.'
Extension: For faster students, ask them to use two prepositional phrases in one sentence. For slower students, provide sentence frames: 'The letter is [preposition] [place].' or 'I will write [preposition] [time].'
Application: Display four sentences from Grammar Island page 91 on the board. Students identify the preposition in each sentence and name whether it shows a relationship in TIME or SPACE. They underline the preposition and circle the object.
Extension: For faster students, ask them to write one sentence with a time preposition and one with a space preposition. For slower students, give them two sentences to analyze instead of four.
Application: Students write one sentence about their letter recipient using BOTH a conjunction and a preposition. Example: 'My Future Self will be taller and older, and I will meet them in five years.' The navigator coaches students to identify which word joins and which word places.
Extension: For faster students, ask them to write two sentences — one where the conjunction comes first, one where the preposition comes first. For slower students, provide a sentence frame: '[Recipient] will be [adjective] and [adjective], and I will [verb] [preposition] [noun].'

Today's PWP focus
Continue drafting your letter using conjunctions to join ideas and prepositions to place them. Circle one conjunction and one preposition you used.
Real-time coaching
Watch for students who write two short sentences when one joined sentence would flow better — coach them to try 'and' or 'but' between the sentences. Also watch for students who overuse 'and' — redirect to 'but' or 'or' when the ideas contrast or offer choices.
Coaching moves
- Project one of yesterday's student sentences on the board and add a conjunction live — show the joining move before students try it in their own letters.
- When you see a student write two short choppy sentences, whisper-coach: 'What if you joined those with and or but?'
- When a student uses 'and' three times in a row, ask: 'Which of these ideas contrasts with the others? Try but instead.'
- Circulate and name aloud one strong preposition you see — 'I love how you placed your recipient in five years with that in phrase.'
- Last 3 minutes: students re-read their letter aloud to themselves, listening for one place where a conjunction or preposition made the sentence flow better.

Workshop recap
Today we met conjunctions, the glue words that join two ideas into one sentence, and prepositions, the words that place things in time or space.
Routine close: Today we thought about what we used to think about sentences — that one sentence holds one idea — and now we think one sentence can hold two ideas joined by a conjunction.
Read aloud
Read aloud one sentence from your letter where you used a conjunction to join two ideas, or one sentence where you used a preposition to place something.
Navigator names what worked
Name what makes a conjunction work — it joins words or ideas of the same kind, like two nouns or two verbs, not a noun and an adjective.
Restate the reminder
Conjunctions join ideas, prepositions place them — your letter uses both to make sentences that flow.
Preview
If installment closed: Next lesson we practice conjunctions and prepositions in more sentences, and you'll write another letter using both.
If not closed: Finish your letter at home — write at least three more sentences using conjunctions to join ideas or prepositions to place them. Circle one conjunction and one preposition when you're done, and bring it to the next lesson. → Next lesson we practice conjunctions and prepositions in more sentences, and you'll continue the letter you started.
