What it is. You have both words and you know both meanings. Grade 8 is where you stop needing to think about which.
Why our test works. Unit 1 was met in Grade 3 and again in Grade 6, so nothing here is new and a child will recognize every item. Recognition is exactly the trap: it feels like knowledge and produces nothing. The test asks about SPONTANEOUS USE because that is the only evidence that separates a word a child owns from one they can pick out of a line-up. At this level no sentence stems are offered, so nothing hides the difference.
Leans on. Grades 3 and 6 met this unit. Grade 8 removes the scaffolding.
Watch for. Do not accept a correct answer to a direct question as evidence. Look at their project draft — that is where ownership shows.
Use 12 school words in sentences of your own, and choose which version suits who is reading. The worked example is built on We could not ascertain the cause., ringing ascertain. The class reads Writing Book 8, p.45 — our own page, so a child who was absent can still get the lesson.
You open by saying where this sits — what it follows and what it is part of — in one sentence, and then you give them the reason it matters, in your own words, for about ten seconds.
Then you do one yourself, on screen, one click per piece: the word ascertain alone first, and you wait — let them look at it before you give them the meaning. Then find out arrives beside it, and you point from one to the other with your hand. Then the sentence underneath: We could not ascertain the cause.. Three clicks, three things said. Do not let the whole slide arrive at once — a slide that arrives whole gives the answer before the question is asked.
The We-do is the main whiteboard moment of the lesson — short answers, boards up on your signal, every child visible at once. Class rewrites two everyday sentences into school-word, then judges one case where the everyday version is BETTER. Discuss in pairs using the frames. If the answer is a whole sentence rather than a word, take it on their notebooks instead, because a sentence written on a whiteboard is written once and destroyed.
They open Writing Book 8 to page 45 and read it with you. Stop at the worked example and let them look at it.
Exit directions in full, standing still, before anyone moves. Then they work alone through the five steps — match, choose, frame, write their own. The frames stay on screen while they write: No frames today. You have had them three times; the words are yours. Say both halves of that — the frame is there if they need it, and it is better writing without it. Walk and note who used it; that is your group for tomorrow, not a mark against them today.
You close on the exit direction — Say one sentence using ascertain. — taken from every child before anyone stands, and then the line you want them to still have tomorrow: And know when the plain word is the better one.
