The complete 5-day Pythagoras' Theorem unit for Grade 9 Math. Open a folder, click a file, teach a lesson.

What's included

• Master unit plan (.docx) — ONE document with every day's lesson plan inside, plus a unit cover (big picture, prerequisites, end-of-unit goals, concrete resources, assessment notes) and a scope-and-sequence table. Read the whole unit at one sitting before you teach Day 1.
• 5 individual teacher lesson plans (.docx) — same per-day plans, also delivered as separate files so you can print just the day you need
• 5 projectable slide decks (.pptx) — one per daily lesson
• 5 student worksheets (.docx) — one per daily lesson, with full answer keys
• 5 differentiated exit quizzes (.docx) — three tiers per day (Support / Core / Stretch, 9 questions total), with answer keys — quick formative assessment to check each day's LO
• Recipe-graded across every day — varied question types, real-world contexts, differentiated three-tier practice

Standards alignment

• CCSS: 8.G.B.6, 8.G.B.7, 8.G.B.8

Differentiation

• Support — scaffolded with smaller numbers, simpler contexts, visual prompts.
• Core — age-related expectation (the bulk of the class).
• Stretch — greater-depth reasoning, multi-step worded problems, generalisation.
• Dig Deeper — early-finisher extension every day.

Daily learning objectives

• Day 1: The Theorem — State Pythagoras' theorem and identify the hypotenuse. CCSS: 8.G.B.6
• Day 2: Find The Hypotenuse — Use a² + b² = c² to find the hypotenuse. CCSS: 8.G.B.7
• Day 3: Find A Leg — Rearrange a² + b² = c² to find a leg. CCSS: 8.G.B.7
• Day 4: Pythagorean Triples — Recognize common Pythagorean triples (3-4-5, 5-12-13, 8-15-17). CCSS: 8.G.B.6
• Day 5: Worded Problems — Apply Pythagoras' theorem to a real-world context. CCSS: 8.G.B.7, 8.G.B.8

Use it as

• Whole-unit teach — open the master plan, walk through Day 1, repeat for 5 days.
• Sub cover bank — pull out any single day for cover lessons; each lesson is self-contained.
• Department resource — share across a team for consistent delivery.
• Homework pack — print the 5 worksheets and use the unit as a half-term homework cycle.

Answer keys

• Every practice question has an answer-key entry — worksheet, exit quiz, dig-deeper.
• Inverse-verified at packaging time — every numerical answer is recomputed by code; zero key errors across the 5-lesson unit.

Why this is a unit, not a worksheet pack

• Sequenced — the lessons build on each other from foundation through assessment
• Spiral retrieval — every day starts with retrieval of prior learning
• Variety baked in — no flat compute-only lessons; every day has reasoning, worded problems, spot-the-mistake, cloze, multi-part scaffolds
• Premium quality at a unit price — 5 lessons for less than the cost of buying them all individually

Format

• Microsoft PowerPoint (.pptx) — 16:9 widescreen
• Microsoft Word (.docx) — A4 / US Letter friendly
• US spelling and CCSS alignment
• Verdana / Calibri only — renders cleanly on any school PC
