The big idea

Ten hundreds make one thousand. The pattern of the places keeps going.

Slide by slide

#	On the screen	What you say
1	Today — WARM-UP	Point at the five parts. Name where we are.
2	Numbers to 10,000	First lesson of the year, so there is nothing behind us yet. We start at the idea.
3	Today — I DO	We are at I DO. Boards down and flat.
4	Ten hundreds make one thousand. The pattern of the places keeps going.	Read this out. Do not explain it yet — the example explains it.
5	[100] × 10 build 1 of 5	Ten hundred-flats.
6	[100] × 10 [1000] build 2 of 5	Stacked, they make one thousand.
7	[100] × 10 [1000] [1000] [1000] [1000] build 3 of 5	Three thousands.
8	[100] × 10 [1000] [1000] [1000] [1000] 3 thousands 2 hundreds 4 tens 6 ones build 4 of 5	Two hundreds, four tens, six ones.
9	[100] × 10 [1000] [1000] [1000] [1000] 3 thousands 2 hundreds 4 tens 6 ones 3,246 build 5 of 5	Written as a numeral, with the comma.
10	Write the number: 5 thousands, 1 hundred, 8 tens, 3 ones.	Now the same thing on a new one. Watch — nothing on your boards.
11	Thousands: 5. Hundreds: 1. Tens: 8. Ones: 3. 5,183 answer — own slide	I say every step aloud as I write it. The board keeps all of it.
12	Today — WE DO	We are at WE DO. Boards up.
13	Write the number: 2 thousands, 7 hundreds, 4 tens, 9 ones.	Build it place by place, left to right. Boards up.
14	2,749 answer — own slide	Boards up. Everyone at once — check yours against this.
15	Write the number: 6 thousands, 0 hundreds, 5 tens, 0 ones.	Two empty places here. Every place still needs a digit.
16	6,050 answer — own slide	Boards up. Everyone at once — check yours against this.
17	Today — YOU DO	We are at YOU DO. Boards down, books open.
18	Dimensions 3A — page 6	Open your books to this page. Wait — do not start yet.
19	Do — page 6	These are the book's own problems, same type as the three we have just done. Work them in the book.
20	Today — CLOSURE	Last part. Answers up.
21	“Does every place have a digit, even the empty ones?”	This is the question to ask yourself every time, not just today.
22	Write four thousand and six as a numeral.	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
6,050 has two zeros in different roles. A child who writes 650 has treated an empty place as no place at all — the single most consequential misunderstanding in place value.
