The big idea

To compare two numbers, match them one to one. Whichever has some left over is greater.

2Put in order, least to greatest: 8, 3, 5Boards up on three. This is yesterday's work — Order Numbers. Do not help each other; I need to see what each of you kept.
33, 5, 8 answer — own slideShow me. Everyone at once. Check your own board against this.

6 > 4 4 < 6 build 5 of 5
So 6 is greater than 4. And 4 is less than 6.
11Which is greater, 5 or 3?Now the same thing on a new one. Watch — nothing on your boards.
12Match five against three.
Two are left over on the 5 side.
5 is greater than 3. 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.
14Which is greater, 7 or 9?Match them in your head, then boards up with the greater number.
159 is greater than 7. answer — own slideBoards up. Everyone at once — check yours against this.
16Which is less, 6 or 2?This one asks for LESS. Read it twice before you write.
172 is less than 6. 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 13Open your books to this page. Wait — do not start yet.
20Do — page 13These 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“Am I being asked which is greater, or which is less?”This is the question to ask yourself every time, not just today.
23Show the greater number: 4 or 8?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.

CLOSUREanswers displayed2-3 minboards downAnswers on the board, children check their own. Mark nothing here.
Watch for
The second WE DO switches to LESS on purpose. Children answer the question they expected rather than the one asked, and this is the cheapest place in the year to catch it.
