{"product_id":"find-the-hidden-number-year-3","title":"Find the Hidden Number - Year 3","description":"\u003cp\u003eFinding a missing number is easier when students know what the whole represents. This unit guides Year 3 learners through unknowns in different equation positions, beginning with models and guided decisions before moving to mixed practice, a partner challenge and an independent assessment. Students explain their choice and check a result rather than relying on a keyword rule.\u003c\/p\u003e\u003cp\u003eThe teaching sequence spans five 45–60-minute lessons. Start with 27 + ? = 64 and ? − 27 = 37 to discuss the whole and known part. Model how subtraction finds a missing part and how combining parts finds a missing whole. Students then compare related equations, repair a reversed-subtraction claim and apply the method to fresh values. The teacher guide includes equipment, access options, keys and marking guidance.\u003c\/p\u003e\u003ch2\u003eWhat's included\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e26-page unit-plan PDF with contents and three-page teacher guide.\u003c\/li\u003e\n\u003cli\u003eColour part–whole display and 12 model cards.\u003c\/li\u003e\n\u003cli\u003eThree practice sheets, two rehearsal sheets and one assessment, each followed immediately by a matching red-answer page.\u003c\/li\u003e\n\u003cli\u003ePartner-game instructions and 12 challenge cards.\u003c\/li\u003e\n\u003cli\u003eCriterion-based rubric with space for evidence and a next teaching step.\u003c\/li\u003e\n\u003cli\u003eEditable 18-slide PowerPoint teaching presentation.\u003c\/li\u003e\n\u003cli\u003eEditable 26-slide PowerPoint question-and-answer quiz.\u003c\/li\u003e\n\u003cli\u003e70-page watermarked Preview PDF.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eLearning focus\u003c\/h2\u003e\u003cp\u003eIdentify the whole and known part; find missing addends, subtrahends and minuends; justify answers with a model or inverse relationship; check a result in the original equation.\u003c\/p\u003e\u003ch2\u003eClassroom use\u003c\/h2\u003e\u003cp\u003eFive lessons of approximately 45–60 minutes.
