What it is. The red margin divides the page into two jobs: numbering on the left, writing on the right.
Why our test works. The margin is already printed, so the rule costs nothing to enforce and pays every time a page is read back. A child who numbers inside the writing area loses the number the moment the line wraps.
Leans on. Lesson 4's move onto notebook ruling.
Watch for. Grade 2 does not have the full heading yet — that arrives midyear. Do not add it here or the lesson carries two new things at once.
Use the notebook's red margin and its line spacing the way the page intends. The worked example is the one you build on the board: Teacher shows the notebook page and names what practice paper never had: a red margin with The class reads the teaching page printed at the top of the sheet — our own writing, 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, building it on the board and leaving it up: Teacher shows the notebook page and names what practice paper never had: a red margin with numbers to its left, and lines closer together than the practice bands. Both papers stay side by side. The board copy is what they look back at when they stall, so it stays there for the whole lesson.
The We-do is the main whiteboard moment of the lesson — short answers, boards up on your signal, every child visible at once. Class finds the red margin, writes one number left of it, and writes one sentence right of it. If the answer is a whole sentence rather than a word, take it on the printed sheet instead, because a sentence written on a whiteboard is written once and destroyed.
They read the teaching page — printed at the top of today's sheet — with you, either read-aloud or FASE, never round robin. Stop at the worked example and let them look at it.
Exit directions in full, standing still, before anyone moves. Then they work alone: Copy two sentences into notebook ruling, starting right of the red margin every time.
You close on the exit direction — Show me your writing starting right of the red line. — taken from every child before anyone stands, and then the line you want them to still have tomorrow: Numbers left of the red line, writing right of it.
