They work out that 2 hundreds, 6 tens and 4 ones, 1 hundred and 16 tens and 4 ones, and 2 hundreds, 5 tens and 14 ones all make 264. They order 407, 478, 483 and 487 and disprove the claim that the largest ones digit gives the largest number. Later they place numbers on a line from 400 to 500, calculate 398 + 27 two ways, and find out how many of 560 library books are left after 135 are borrowed and 48 returned.\u003c\/p\u003e\n\u003ch2\u003eWhat's Included\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e31-page student book with a cover and a \"Your learning journey\" page for prior knowledge\u003c\/li\u003e\n\u003cli\u003eSix 4-page modules: learning text and examples, Tasks 1 and 2 with a help box, Task 3 plus a \"think further\" application with sketch space, and extra practice with a reflection\u003c\/li\u003e\n\u003cli\u003e\"My project\" over two pages: students build a number museum for a number between 100 and 999\u003c\/li\u003e\n\u003cli\u003e\"Learning check without the text\" with one prompt per module\u003c\/li\u003e\n\u003cli\u003e\"My glossary and reflection\" page with a term for each module\u003c\/li\u003e\n\u003cli\u003e14-page teacher guide: objectives, six-step lesson sequence, differentiation, answer pages for every module, project support and expected learning-check responses\u003c\/li\u003e\n\u003cli\u003eFour assessment criteria scored 0–4 points\u003c\/li\u003e\n\u003cli\u003ePrint-ready A4 PDF that prints on US Letter with fit-to-page\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSix Modules\u003c\/h2\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eBundling and place value\u003c\/strong\u003e — ten ones make a ten, ten tens make a hundred, and why 305 is not 35\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRepresenting numbers\u003c\/strong\u003e — digits, place-value sums and exchanging bundles without changing the total\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComparing and ordering\u003c\/strong\u003e — comparing from the left, the \u0026lt; and \u0026gt; signs, and ordering 805, 850, 580 and 508\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber lines and neighbors\u003c\/strong\u003e — reading tick-mark intervals and finding the neighboring tens and hundreds of 463\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEfficient calculation\u003c\/strong\u003e — compensation strategies such as 400 + 27 − 2 and checking with an estimate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWord problems and checking\u003c\/strong\u003e — finding the relevant numbers, spotting the one you do not need and answering with a unit\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch2\u003eStudents Will Learn To\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRead and write three-digit numbers by place value, including numbers with a zero\u003c\/li\u003e\n\u003cli\u003eCompare and order numbers to 1000 and place them on a number line with a given interval\u003c\/li\u003e\n\u003cli\u003eAdd and subtract mentally by reaching the next hundred and compensating\u003c\/li\u003e\n\u003cli\u003eSolve word problems, leave out irrelevant numbers and check the answer against the context\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePerfect For\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGrade 3 place value and mental math units, or a grade 4 review at the start of the year\u003c\/li\u003e\n\u003cli\u003eSmall-group intervention for students who mix up digits and place values\u003c\/li\u003e\n\u003cli\u003eRoughly maps to Years 3–4 number and place value in England (lower KS2) and Years 3–4 in Australia\u003c\/li\u003e\n\u003cli\u003eHomeschool families and sub plans, since each module has a worked example and its own answer page\u003c\/li\u003e\n\u003cli\u003eMath centers that use place-value blocks and a class number line\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhy Teachers Choose This Unit\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAnswer pages for Tasks 1–3 and the extra practice in all six modules\u003c\/li\u003e\n\u003cli\u003eThree paths in the teacher guide: support, core path and extension\u003c\/li\u003e\n\u003cli\u003eFour 0–4 point criteria: key concept, example and reasoning, application\/product, revision\u003c\/li\u003e\n\u003cli\u003eModules usable separately; the whole unit runs about 8–12 lessons\u003c\/li\u003e\n\u003cli\u003eIllustrations are AI-generated discussion prompts; exact numbers come from the labeled tables and number lines\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAlso part of the \u003ca href=\"https:\/\/teachlessons.us\/products\/discovery-bundle-4-units-numbers-to-1000-stone-age-patterns-printing-voices-songs-grades-3-6\"\u003e\u003cstrong\u003eDiscovery Bundle\u003c\/strong\u003e\u003c\/a\u003e: four complete units for $49.90, or all ten units in the \u003ca href=\"https:\/\/teachlessons.us\/products\/complete-learning-books-bundle-10-units-grammar-math-science-history-esl-art-music-grades-3-6\"\u003e\u003cstrong\u003eComplete Learning Books Bundle\u003c\/strong\u003e\u003c\/a\u003e for $99.90.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eCreated with AI assistance: ChatGPT (OpenAI) and Claude (Anthropic).
