This complete unit combines explicit teaching, worked examples, practical games and carefully sequenced independent practice so students can move from identifying the whole and parts to solving and explaining mixed problems.\u003c\/p\u003e\u003cp\u003eThe 24-slide editable PowerPoint presentation introduces bar-model structure, models addition and subtraction, explores unknown wholes and missing parts, and develops operation choice and mathematical reasoning. Colour displays, 16 task cards and two games provide supported and collaborative practice. Seven black-and-white worksheets progress from matching models to drawing representations and solving mixed word problems. A two-page assessment, matching answer pages and a five-level rubric support evidence-based evaluation.\u003c\/p\u003e\u003cp\u003eUse the unit as a five-lesson teaching sequence or select individual components for small groups, intervention, homework, revision or assessment.\u003c\/p\u003e\u003ch2\u003eWhat’s Included\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e24-slide editable teaching presentation\u003c\/li\u003e\n\u003cli\u003e22-slide editable quiz with 10 question-and-answer pairs\u003c\/li\u003e\n\u003cli\u003e32-page unit plan\u003c\/li\u003e\n\u003cli\u003eFour-display set covering bar-model basics, the whole, missing parts and operation connections\u003c\/li\u003e\n\u003cli\u003e16 Bar Model Challenge Task Cards, recording sheet and answer page\u003c\/li\u003e\n\u003cli\u003eRace to the Whole and Missing Part Mission games\u003c\/li\u003e\n\u003cli\u003eSeven worksheets covering matching, addition, subtraction, drawing models, word problems, equal parts and mixed challenges\u003c\/li\u003e\n\u003cli\u003eMatching answer pages for the recording sheet and all seven worksheets\u003c\/li\u003e\n\u003cli\u003eTwo-page Bar Model Problem-Solving Assessment with answers\u003c\/li\u003e\n\u003cli\u003eFive-level landscape rubric\u003c\/li\u003e\n\u003cli\u003e10 matching answer pages in total\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eLearning Focus\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eIdentify the whole and the parts in a part-part-whole model\u003c\/li\u003e\n\u003cli\u003eRepresent addition and subtraction stories with bar models\u003c\/li\u003e\n\u003cli\u003eFind an unknown whole or a missing part\u003c\/li\u003e\n\u003cli\u003eConnect bar models, number sentences and word problems\u003c\/li\u003e\n\u003cli\u003eChoose an appropriate operation\u003c\/li\u003e\n\u003cli\u003eExplain and justify mathematical reasoning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eClassroom Use\u003c\/h2\u003e\u003cp\u003eSuitable for whole-class explicit teaching and worked examples, guided mathematics groups, intervention, partner task-card work and games, independent practice, differentiated consolidation, formative quiz review and summative assessment.\u003c\/p\u003e\u003ch2\u003eFormats and Answer Support\u003c\/h2\u003e\u003cp\u003eFiles are supplied in PDF and editable Microsoft PowerPoint PPTX formats.
