The big idea

A digit's VALUE is what it is worth where it stands — not the digit itself.

Slide by slide

#	On the screen	What you say
1	Today — WARM-UP	Point at the five parts. Name where we are.
2	Write 3 thousands, 0 hundreds, 7 tens, 2 ones.	Boards up on three. This is yesterday's work — Numbers to 10,000. Do not help each other; I need to see what each of you kept.
3	3,072 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 digit's VALUE is what it is worth where it stands — not the digit itself.	Read this out. Do not explain it yet — the example explains it.
6	4,573 build 1 of 5	The number 4,573.
7	4,573 4 → 4,000 build 2 of 5	The 4 is in the thousands place. Its value is 4,000.
8	4,573 4 → 4,000 5 → 500 build 3 of 5	The 5 is in the hundreds place. Its value is 500.
9	4,573 4 → 4,000 5 → 500 7 → 70 build 4 of 5	The 7 is in the tens place. Its value is 70.
10	4,573 4 → 4,000 5 → 500 7 → 70 4,573 = 4,000 + 500 + 70 + 3 build 5 of 5	The 3 is ones. 4,000 + 500 + 70 + 3.
11	What is the value of the 6 in 2,614?	Now the same thing on a new one. Watch — nothing on your boards.
12	The 6 is in the hundreds place. Six hundreds is 600. 600 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 is the value of the 8 in 8,192?	Name the place first, then the value. Boards up.
15	Thousands place. 8,000 answer — own slide	Boards up. Everyone at once — check yours against this.
16	What is the value of the 3 in 5,038?	Find the 3 carefully — count the places from the right.
17	Tens place. 30 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 3A — page 10	Open your books to this page. Wait — do not start yet.
20	Do — page 10	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	“Which place is it in, and what is one of those worth?”	This is the question to ask yourself every time, not just today.
23	What is the value of the 9 in 4,900?	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. Grade 3 may drop this if the previous lesson was a review — from Grade 4 it is not optional.
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
5,038 puts the 3 in the tens with a zero beside it. Children read past the zero and call it hundreds. Have them count places from the right, with a finger, every time.
