The grammar behind this lesson — read this before you teach it.PrepositionWhat it is. A preposition shows how something sits in relation to something else — in place, in time, or in the way it belongs.
Why our test works. The test asks whether another relationship word could stand in its place — in the box, on the box, under the box. It works because prepositions form a small closed set that all do the same job, so they are interchangeable in a way that nouns and verbs are not. If swapping in another relationship word keeps the sentence sensible, the word is a preposition.
Leans on. Nouns, because a preposition always has a noun after it. If nothing follows, it is doing a different job.
Watch for. The same word can be a preposition or an adverb — he went in has no noun after in, so there it is not a preposition. That is why the test asks about what follows, not just about the word itself.
What this lesson is
A review day. No new concept: today drills subject. Choose the focus from the last assessment rather than from a plan made months ago — the sheet works on whatever you pick. The worked example is built on The tremulous dog on the twenty-third floor has acrophobia., ringing dog.
Why it matters — say this in your own words, about ten seconds.
“Careful words make careful thinking.”
A different reason every lesson, on purpose. It is not on a slide and it
is not a script — if you have a better reason today, use yours. What should land is the
idea, not a sentence they can recite.
Recall — sixty seconds, before anything new
Retrieve: Verb + Adverb · Adverb. Ask for it before you introduce anything, take the answers from boards rather than from hands so you see all thirty, and do not re-teach — note who has lost it and carry on. This is the middle of the launch: context, then this, then why it matters. Only what today leans on — a minute spent retrieving something unrelated costs the same and buys nothing, and the child who cannot recall the prerequisite is the one you will lose in the I-do.
How it goes
- Ten seconds on why it matters — “Careful words make careful thinking.” Your words, not those; it is a different reason every lesson so what lands is the idea rather than a sentence they can recite.
- Then you do one yourself, on screen, one click per move: The tremulous dog on the twenty-third floor has acrophobia. · the question · ring dog · name it a subject. Do it exactly the way you want it done — this is the task they are about to do on their boards, not an easier one.
- You build the same thing on the board and leave it up for subject. The four steps are identical in every lesson of this unit — sentence, question, test, answer — so the children read the method rather than the layout, and today's board shows The tremulous dog on the twenty-third floor has acrophobia. still marked when they start work.
- The We-do runs 1 items on whiteboards — We see the present that is, we remember the past that was, and we wonder about the future that will be.Who or what is this about?. You are scanning for who applies the question and who is guessing from meaning; those look identical on a right answer and completely different on a wrong one.
- Exit directions in full, standing still, before anyone moves — Sheet and pencil · Read the question above each one BEFORE you answer it · Find the subject. Then they work alone, with the same worked example printed at the head of their sheet.
- Close on We see the present that is, we remember the past that was, and we wonder about the future that will be. — an item they have not met, so it measures rather than reminds — then the line they leave with: “The subject is who or what it is about.”
- Watch for: Marks the first word rather than the subject — The subject usually starts the sentence, so position works often enough to hide. If you see it: “Who or what is it ABOUT? Say the whole naming part.” (Remedial sheet 19.)
