Students use the windows of a friendly house as labeled arrays to connect equal groups, multiplication and division.\u003c\/p\u003e\u003cp\u003eThe workbook uses one convention throughout: the first factor counts the rows and the second counts the windows in each row. Students begin with 3 rows of 4 windows (4 + 4 + 4 = 12), then turn an array a quarter turn to see that 3 × 4 and 4 × 3 both make 12, and that switching the factors in 5 × 5 changes nothing. They find missing factors by listing every array of 12 windows, and they build the fact family for 2, 5 and 10. One question asks whether 2, 4 and 9 can make a fact family, and another asks them to correct 12 ÷ 4 = 8. Later they break 7 × 5 into 5 × 5 and 2 × 5, and check a window question that cannot be solved because information is missing. Each block has Understand, Practice, Explore and Apply pages.\u003c\/p\u003e\u003ch2\u003eWhat's Included\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e28-page student workbook with six four-page learning blocks, a learning check (p. 27) and a word bank (p. 28)\u003c\/li\u003e\n\u003cli\u003e12-page teacher guide with answers, preparation notes and differentiation\u003c\/li\u003e\n\u003cli\u003eMixed prompts: draw, build with counters, explain, correct a mistake\u003c\/li\u003e\n\u003cli\u003eEditable DOCX text version (pagination may differ)\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\u003ch2\u003eSix Learning Blocks\u003c\/h2\u003e\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eEqual groups\u003c\/strong\u003e — write addition and multiplication sentences for rows of windows, and see why 5 + 2 does not count five baskets of two keys.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTurn an array\u003c\/strong\u003e — switch the factors in 3 × 4 or 2 × 6 and explain why the total stays the same.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFind the missing factor\u003c\/strong\u003e — solve 3 × __ = 12 and list all arrays of 12; 18 lanterns in 3 equal rows gives 18 ÷ 3 = 6.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA fact family\u003c\/strong\u003e — write four related facts for 2, 5 and 10, and tell sharing 20 cookies from packing them in bags.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBreak apart a larger array\u003c\/strong\u003e — use 5 × 4 + 2 × 4 for 7 × 4, and spot that 5 rows plus 4 rows is nine, not eight.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCheck a word problem\u003c\/strong\u003e — sketch, write a number sentence, and decide when a question has too little information.\u003c\/li\u003e\n\u003c\/ol\u003e\u003ch2\u003eStudents Will Learn To\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConnect equal groups, addition and multiplication\u003c\/li\u003e\n\u003cli\u003eRead an array by rows and switch the factors\u003c\/li\u003e\n\u003cli\u003eFind a missing factor and use division to check multiplication\u003c\/li\u003e\n\u003cli\u003eBreak apart a larger array to make an easier calculation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePerfect For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHalloween week in Grades 2–3, or the fall-themed alternative The Mysterious Fall House\u003c\/li\u003e\n\u003cli\u003eSmall-group math blocks and early finishers\u003c\/li\u003e\n\u003cli\u003eSub plans: one block needs only the workbook pages, counters and the answer key\u003c\/li\u003e\n\u003cli\u003eArrays practice before or after a multiplication unit\u003c\/li\u003e\n\u003cli\u003eUK and Australia: roughly maps to Year 3–4 (UK) and Year 3 (AU) multiplication and division\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy Teachers Choose This Unit\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThe guide gives answers and error-diagnosis advice: counting, wrong operation and equal groups need different support\u003c\/li\u003e\n\u003cli\u003eThe teacher guide gives SUPPORT, CORE and CHALLENGE guidance\u003c\/li\u003e\n\u003cli\u003eOnly labeled window arrays are counting models; decorative illustrations are not, which keeps counting honest\u003c\/li\u003e\n\u003cli\u003eStudents explain and correct, so the focus stays on thinking rather than speed\u003c\/li\u003e\n\u003cli\u003eDivision is introduced through models, so students need only counting and grouping to start\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003ePair it with \u003ca href=\"\/products\/haunted-house-classroom-adventure-halloween-learning-stations-grades-2-4\"\u003eHaunted House Classroom Adventure\u003c\/a\u003e and \u003ca href=\"\/products\/haunted-house-for-sale-descriptive-writing-workshop-grades-3-4\"\u003eHaunted House for Sale!\u003c\/a\u003e for a Halloween week across math and writing.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eCreated with AI assistance: ChatGPT (OpenAI).
