What this lesson is
A review day. No new concept: today drills subject complement, phrases, objects of prepositions. 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 NOT between compound subject complements: He was angry and tired., ringing tired.
Why it matters — say this in your own words, about ten seconds.
“A writer who knows the parts can build anything.”
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: Commas in a series · Re-teach Level One + Re-teach Level Two + Re-teach Level Three. 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 — “A writer who knows the parts can build anything.” 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: NOT between compound subject complements: He was angry and tired. · the question · ring tired · name it the subject complement. 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 complement, phrases, objects of prepositions. 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 NOT between compound subject complements: He was angry and tired. still marked when they start work.
- The We-do runs 4 items on whiteboards — He's still blasting Poodle's feathers and What?'s hairs and Sidney's shell.Does it tell me about the subject?, Cover your toes, and don't come H the shadow so fast.Does this group act like one word?, Notice that the noun sidewalk is almost like a direct object.Does this group act like one word?, The preposition relates beans to another word in the sentence, dog.Preposition — what?. 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 complement or the phrase or the objects of preposition. Then they work alone, with the same worked example printed at the head of their sheet.
- Close on The action does not have to act on a direct object. — an item they have not met, so it measures rather than reminds — then the line they leave with: “The complement completes the subject.”
- Watch for: Confuses the complement with a direct object — Both sit after the verb. If you see it: “Is the verb DOING something to it, or telling you what the subject IS?” (Remedial sheet 23.)
