The complete 6-day Prime Numbers And Proof unit for Grade 7 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.
• 6 individual teacher lesson plans (.docx) — same per-day plans, also delivered as separate files so you can print just the day you need
• 6 projectable slide decks (.pptx) — one per daily lesson
• 6 student worksheets (.docx) — one per daily lesson, with full answer keys
• 6 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: 6.NS.B.4, 4.OA.B.4
• Note: the proof and reasoning days extend beyond the listed CCSS standards; the codes anchor the primes, factor pairs, HCF and LCM content.

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: Prime Numbers — Identify prime numbers and composite numbers. CCSS: 4.OA.B.4
• Day 2: Factors And Multiples — List factors and multiples. CCSS: 4.OA.B.4, 6.NS.B.4
• Day 3: Prime Factor Decomposition — Write a number as a product of primes. CCSS: 6.NS.B.4
• Day 4: HCF — Find highest common factor using prime factors. CCSS: 6.NS.B.4
• Day 5: LCM — Find lowest common multiple using prime factors. CCSS: 6.NS.B.4
• Day 6: Counter-Example And Proof — Use a counter-example to disprove a statement. CCSS: MP.3

Use it as

• Whole-unit teach — open the master plan, walk through Day 1, repeat for 6 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 6 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 6-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 — 6 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
