| 1 | Today — WARM-UP | Point at the five parts. Name where we are. |
| 2 | Write the first four multiples of 11. | Boards up on three. This is yesterday's work — Multiples. Do not help each other; I need to see what each of you kept. |
| 3 | 11, 22, 33, 44 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 | Every whole number above 1 breaks down into primes in exactly one way. A prime has no factors but 1 and itself. | Read this out. Do not explain it yet — the example explains it. |
| 6 | 60 = 6 × 10 build 1 of 5 | Break down 60. I take any factor pair. |
| 7 | 60 = 6 × 10 60 = 2 × 3 × 10 build 2 of 5 | Neither is prime, so I keep going. 6 = 2 × 3. |
| 8 | 60 = 6 × 10 60 = 2 × 3 × 10 60 = 2 × 3 × 2 × 5 build 3 of 5 | 10 = 2 × 5. |
| 9 | 60 = 6 × 10 60 = 2 × 3 × 10 60 = 2 × 3 × 2 × 5 60 = 2 × 2 × 3 × 5 build 4 of 5 | All four are prime. I order them. |
| 10 | 60 = 6 × 10 60 = 2 × 3 × 10 60 = 2 × 3 × 2 × 5 60 = 2 × 2 × 3 × 5 unique: 2 × 2 × 3 × 5 build 5 of 5 | Starting from 4 × 15 instead gives the same primes. Always does. |
| 11 | Write 36 as a product of primes. | Now the same thing on a new one. Watch — nothing on your boards. |
| 12 | 36 = 4 × 9. 4 = 2 × 2 and 9 = 3 × 3. 36 = 2 × 2 × 3 × 3 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 84 as a product of primes. | Any starting pair is allowed. Keep splitting until every factor is prime. Boards up. |
| 15 | 84 = 4 × 21 4 = 2 × 2, 21 = 3 × 7 2 × 2 × 3 × 7 answer — own slide | Boards up. Everyone at once — check yours against this. |
| 16 | Write 45 as a product of primes. | One of these primes appears twice. |
| 17 | 45 = 9 × 5 9 = 3 × 3 3 × 3 × 5 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 7A — page 4 | Open your books to this page. Wait — do not start yet. |
| 20 | Do — page 4 | 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 | “Is every factor on my list prime?” | This is the question to ask yourself every time, not just today. |
| 23 | Write 50 as a product of primes. | One last board. Then we are finished. |
| 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. |
