The big idea

Numbers have an order, and each one is exactly 1 more than the one before it.

Slide by slide

#On the screenWhat you say
1Today — WARM-UPPoint at the five parts. Name where we are.
2How many are in the empty box?Boards up on three. This is yesterday's work — The Number 0. Do not help each other; I need to see what each of you kept.
30 answer — own slideShow me. Everyone at once. Check your own board against this.
4Today — I DOWe are at I DO. Boards down and flat.
5Numbers have an order, and each one is exactly 1 more than the one before it.Read this out. Do not explain it yet — the example explains it.
65 2 8 1 build 1 of 5I write the numbers I know, out of order.
75 2 8 1
5 2 8 1 → 1 build 2 of 5
Which is the least? I count up from 0 to find it: 0, 1 — there it is.
85 2 8 1
5 2 8 1 → 1
→ 1 2 build 3 of 5
Next least is 2.
95 2 8 1
5 2 8 1 → 1
→ 1 2
→ 1 2 5 build 4 of 5
Then 5.
105 2 8 1
5 2 8 1 → 1
→ 1 2
→ 1 2 5
→ 1 2 5 8 build 5 of 5
Then 8. Least to greatest.
11Put in order, least to greatest: 4, 1, 3Now the same thing on a new one. Watch — nothing on your boards.
12Count up: 1 comes first.
Then 3.
Then 4.
1, 3, 4 answer — own slide
I say every step aloud as I write it. The board keeps all of it.
13Today — WE DOWe are at WE DO. Boards up.
14Put in order, least to greatest: 7, 2, 5Find the least first. Boards up when you have all three.
152, 5, 7 answer — own slideBoards up. Everyone at once — check yours against this.
16Put in order, least to greatest: 6, 0, 9Careful — one of these is the zero we met yesterday.
170, 6, 9 answer — own slideBoards up. Everyone at once — check yours against this.
18Today — YOU DOWe are at YOU DO. Boards down, books open.
19Dimensions 1A — page 10Open your books to this page. Wait — do not start yet.
20Do — page 10These are the book's own problems, same type as the three we have just done. Work them in the book.
21Today — CLOSURELast part. Answers up.
22“Did I start from the least, or from the one I noticed first?”This is the question to ask yourself every time, not just today.
23Which is less, 3 or 5? Show the lesser number on your board.One last board. Then we are finished.

Mini whiteboards, by segment

SegmentMWBTimeBoardsWhat to hold
WARM-UPretrieval3-5 minBOARDS UPQuestion 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 1 may drop this if the previous lesson was a review — from Grade 4 it is not optional.
I DOnone — they watch3-4 minboards downBoards 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 DOprimary use5-6 minBOARDS UPOne 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 DOon the sheet4-5 minboards downBoards down. This is the book's problems, worked where the work will be kept.
CLOSUREanswers displayed2-3 minboards downAnswers on the board, children check their own. Mark nothing here.
Watch for
Including 0 is deliberate. A child who puts it last has not connected yesterday's lesson to this one, which is exactly what the warm-up was testing.
