| 1 | Today — WARM-UP | Point at the five parts. Name where we are. |
| 2 | Work out 7 × 400. | Boards up on three. This is yesterday's work — Grade 5 — multiplying by tens. Do not help each other; I need to see what each of you kept. |
| 3 | 2,800 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 | An EXPRESSION is a calculation with no equals sign. An EQUATION states that two expressions are equal. | Read this out. Do not explain it yet — the example explains it. |
| 6 | 3 + 4 × 2 build 1 of 5 | Here is a calculation. |
| 7 | 3 + 4 × 2 expression → value build 2 of 5 | It has no equals sign, so it is an expression. It has a value. |
| 8 | 3 + 4 × 2 expression → value 3 + 4 × 2 = 11 build 3 of 5 | Now I claim its value is 11. |
| 9 | 3 + 4 × 2 expression → value 3 + 4 × 2 = 11 equation build 4 of 5 | An equals sign has appeared. This is now an equation. |
| 10 | 3 + 4 × 2 expression → value 3 + 4 × 2 = 11 equation expression: evaluate · equation: judge build 5 of 5 | An equation can be TRUE or FALSE. An expression can only be evaluated. |
| 11 | Is 5 × 3 − 2 an expression or an equation? Evaluate it. | Now the same thing on a new one. Watch — nothing on your boards. |
| 12 | No equals sign, so it is an expression. Multiplication first: 15 − 2. 13 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 | Is 12 ÷ 4 = 3 an expression or an equation? Is it true? | Look for the equals sign first. Boards up. |
| 15 | Equals sign, so an equation. 12 ÷ 4 = 3, so TRUE. answer — own slide | Boards up. Everyone at once — check yours against this. |
| 16 | Is 8 + 2 × 5 = 50 an expression or an equation? Is it true? | Careful — evaluate properly before you judge it. |
| 17 | Equation. 8 + 10 = 18, not 50. FALSE 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 6A — page 2 | Open your books to this page. Wait — do not start yet. |
| 20 | Do — page 2 | 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 there an equals sign?” | This is the question to ask yourself every time, not just today. |
| 23 | Write one expression and one equation on your board. | 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. |
