The big idea

The places continue: ten thousands sit to the left of thousands, and the comma marks the thousands off in threes.

Slide by slide

#	On the screen	What you say
1	Today — WARM-UP	Point at the five parts. Name where we are.
2	Which is greater, 6,204 or 6,240?	Boards up on three. This is yesterday's work — Grade 3 — comparing four-digit numbers. Do not help each other; I need to see what each of you kept.
3	6,240 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	The places continue: ten thousands sit to the left of thousands, and the comma marks the thousands off in threes.	Read this out. Do not explain it yet — the example explains it.
6	10,000 build 1 of 5	Ten thousands, written out.
7	10,000 40,000 build 2 of 5	Four of them.
8	10,000 40,000 47,000 build 3 of 5	Add 7 thousands.
9	10,000 40,000 47,000 47,260 build 4 of 5	Add 2 hundreds, 6 tens.
10	10,000 40,000 47,000 47,260 47,263 build 5 of 5	And 3 ones. Read it: forty-seven thousand, two hundred sixty-three.
11	Write the value of the 5 in 58,164.	Now the same thing on a new one. Watch — nothing on your boards.
12	The 5 is in the ten thousands place. Five ten-thousands. 50,000 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	Write the value of the 3 in 93,072.	Name the place before you write the value. Boards up.
15	Thousands place. 3,000 answer — own slide	Boards up. Everyone at once — check yours against this.
16	Write the value of the 4 in 40,619.	Count the places from the right, with a finger.
17	Ten thousands place. 40,000 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 5	Open your books to this page. Wait — do not start yet.
20	Do — page 5	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	“How many places from the right is this digit?”	This is the question to ask yourself every time, not just today.
23	What is the value of the 8 in 28,400?	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
Children read 93,072 as 'ninety-three thousand seventy-two' and lose the empty hundreds. Require the whole number read aloud before the answer is written.
