The big idea

A pattern is a rule applied again and again. Find the rule from two steps, then check it against a third.

Slide by slide

#	On the screen	What you say
1	Today — WARM-UP	Point at the five parts. Name where we are.
2	What is the value of the 9 in 392,608?	Boards up on three. This is yesterday's work — Numbers to 1,000,000. Do not help each other; I need to see what each of you kept.
3	90,000 answer — own slide	Show me. Everyone at once. Check your own board against this.
4	Today — I DO	We are at I DO. Boards down and flat.
5	A pattern is a rule applied again and again. Find the rule from two steps, then check it against a third.	Read this out. Do not explain it yet — the example explains it.
6	1,200 1,400 1,600 ___ build 1 of 5	A sequence.
7	1,200 1,400 1,600 ___ 1,200 → 1,400 is +200 build 2 of 5	From the first to the second: what happened?
8	1,200 1,400 1,600 ___ 1,200 → 1,400 is +200 1,400 → 1,600 is +200 build 3 of 5	Check it on the next pair. Same jump.
9	1,200 1,400 1,600 ___ 1,200 → 1,400 is +200 1,400 → 1,600 is +200 rule: + 200 build 4 of 5	The rule is +200. It held twice, so I will use it.
10	1,200 1,400 1,600 ___ 1,200 → 1,400 is +200 1,400 → 1,600 is +200 rule: + 200 1,600 + 200 = 1,800 build 5 of 5	Apply it.
11	What comes next? 3,500 4,000 4,500 ___	Now the same thing on a new one. Watch — nothing on your boards.
12	3,500 → 4,000 is +500. Check: 4,000 → 4,500 is +500. 4,500 + 500 = 5,000 answer — own slide	I say every step aloud as I write it. The board keeps all of it.
13	Today — WE DO	We are at WE DO. Boards up.
14	What comes next? 12,000 11,000 10,000 ___	Find the jump, then CHECK it on the second pair. Boards up.
15	−1,000 each time. 9,000 answer — own slide	Boards up. Everyone at once — check yours against this.
16	What comes next? 2,000 2,200 2,400 ___	Do not assume the jump from the first pair alone.
17	+200 each time. 2,600 answer — own slide	Boards up. Everyone at once — check yours against this.
18	Today — YOU DO	We are at YOU DO. Boards down, books open.
19	Dimensions 4A — page 16	Open your books to this page. Wait — do not start yet.
20	Do — page 16	These are the book's own problems, same type as the three we have just done. Work them in the book.
21	Today — CLOSURE	Last part. Answers up.
22	“Did the rule hold twice, or did I only check it once?”	This is the question to ask yourself every time, not just today.
23	What comes next? 700 1,400 2,100 ___	One last board. Then we are finished.

Mini whiteboards, by segment

Segment	MWB	Time	Boards	What to hold
WARM-UP	retrieval	3-5 min	BOARDS UP	Question up, boards up on the count. Everyone shows at once — a child who waits to see a neighbour's board has not retrieved anything.
I DO	none — they watch	3-4 min	boards down	Boards DOWN and flat. This segment is watching, and a child writing is not watching. Say so once at the start of the year and then hold it.
WE DO	primary use	5-6 min	BOARDS UP	One step, then boards up. Do not let them run ahead to the answer — the point is that everybody is on the same step at the same time.
YOU DO	on the sheet	4-5 min	boards down	Boards down. This is the book's problems, worked where the work will be kept.
CLOSURE	answers displayed	2-3 min	boards down	Answers on the board, children check their own. Mark nothing here.

Watch for
Checking the rule on a SECOND pair is the whole method. A child who reads one jump and runs will be right most of the time and wrong exactly when the question is testing something.
