| Objectives | Students will be able to: (1) read, write and represent numbers to 1,000,000; (2) state the value of any digit. |
|---|---|
| Materials | Extended place charts (HTh TTh Th H T O); national data cards (country populations: Jamaica ~2.8 million, T&T ~1.4 million, Barbados ~280,000); digit cards. |
| Key vocabulary | hundred thousand, million, digit value |
| Engage (starter) | (10 min) The region on cards: Barbados about 280,000 people; Jamaica about 2,800,000 — ten times the digits' journey! National numbers demand six-digit fluency. |
| Develop (main) | (35 min) 1. Chart to hundred-thousands; the million introduced as ten hundred-thousands (the trade rule's grandest performance). 2. Reading protocol: chunk by commas — "two hundred eighty | thousand". 3. Hear-and-write eight with layered zero-traps (405,060). 4. Digit interviews at depth: "the 8 in 280,000 is...?" (Eighty thousand!) |
| Plenary (close) | (10 min) Anchor-desk round: three national figures read broadcast-style. |
| Assessment | 6 of 8 written; interviews at two places; protocol used aloud. |
| Teacher notes | Regional population cards make place value civic — children reading their nation's numbers correctly is quiet citizenship education. |
| Objectives | Students will be able to: (1) write 5- and 6-digit numbers in expanded form and rebuild them; (2) compose numbers from mixed clues. |
|---|---|
| Materials | Expanded strips; clue cards; whiteboards. |
| Key vocabulary | expanded form, compose, decompose |
| Engage (starter) | (10 min) The exploded number: 347,205 blown apart on the board — 300,000 + 40,000 + 7,000 + 200 + 5. Note the missing tens: zeros are SILENCES in the explosion. |
| Develop (main) | (35 min) 1. Decompose four numbers including double-zero cases. 2. Rebuild from shuffled parts (40,000 + 5 + 300,000 + 200 + 7,000 — order the chaos!). 3. Clue construction: "six digits; 4 in the ten-thousands; ones digit double the hundreds..." 4. Author one clue-number per pair for the bank. |
| Plenary (close) | (10 min) Two bank clues cracked publicly. |
| Assessment | Both directions on 3 of 4; one clue-number built; authored clue solvable. |
| Teacher notes | Shuffled-parts rebuilding defeats the rote left-to-right habit — students must THINK in place values, not positions. |
| Objectives | Students will be able to: (1) compare and order numbers to 1,000,000; (2) place large numbers on scaled number lines. |
|---|---|
| Materials | Card sets; long empty number lines (0 to 1,000,000 marked in 100,000s); pegs. |
| Key vocabulary | ascending, descending, scale, position |
| Engage (starter) | (10 min) The stadium claim-off: four attendance figures argued into order by the two-step rule (digits, then left-march). |
| Develop (main) | (35 min) 1. Order six mixed cards ascending. 2. The scaled line challenge: peg 250,000 (halfway to half a million!), 720,000, 95,000 — estimation and place value shaking hands. 3. Between-and-closer questions: "Is 480,000 closer to 400,000 or 500,000?" 4. Descending drill with the vocabulary enforced. |
| Plenary (close) | (10 min) Human line: five card-holders self-place along a rope line; class adjudicates spacing. |
| Assessment | Six ordered; pegs within tolerance; closer-question reasoned. |
| Teacher notes | Line placement at scale is rounding's geometry — Wednesday's rounding lesson will harvest today's spatial sense. |
| Objectives | Students will be able to: (1) round large numbers to any named place; (2) estimate sums/differences of large numbers for real decisions. |
|---|---|
| Materials | Zoom lines; news figures; estimation frames. |
| Key vocabulary | nearest ten thousand, approximately, magnitude |
| Engage (starter) | (10 min) The budget headline: a ministry allocates $4,675,000 — the radio says "about 4.7 million." Rounding runs the news; today we run rounding. |
| Develop (main) | (35 min) 1. One number, four zooms (nearest thousand, ten-thousand, hundred-thousand). 2. Ten mixed roundings at named places. 3. Estimation for decisions: two parish populations totalled roughly — "about how many relief kits?" 4. Sense-checking drill: three computed answers judged reasonable/suspicious against estimates. |
| Plenary (close) | (10 min) Suspicious-answer tribunal: the class convicts one wild answer using estimation evidence. |
| Assessment | 8 of 10 rounded; one decision-estimate; one conviction reasoned. |
| Teacher notes | Estimation as answer-police is the exam skill of the decade — a Grade 6 sitting national assessments next year must already own it. |
| Objectives | Students will be able to: (1) consolidate place value to 1,000,000; (2) complete the week checkpoint. |
|---|---|
| Materials | All kits; checklist; licence stamps. |
| Key vocabulary | All week vocabulary |
| Engage (starter) | (10 min) Medley: one anchor read, one shuffled rebuild, one zoom-rounding. |
| Develop (main) | (35 min) Circuit: T1 read/write/interview one 6-digit number; T2 expanded both directions with a zero-silence; T3 order five cards + peg two on the line; T4 round at two named places + one sense-check verdict. |
| Plenary (close) | (10 min) Millionaire licences stamped. Preview: "Next week the giants MULTIPLY — 2-digit times 2-digit, the full ceremony." |
| Assessment | Checkpoint: six-digit fluency across representation, comparison, rounding. |
| Teacher notes | This week is deliberately computation-light: representation fluency FIRST makes next week's multiplication of large numbers meaningful rather than mechanical. |
