Number System + Objectives of Maths
Place Value · Fractions · Decimals · NCF 2005 · Objectives of Teaching
संख्या पद्धति + गणित शिक्षण के उद्देश्य
🎯 Learning Objectives
- Place value (स्थानीय मान) — 5-digit numbers समझना
- Fractions — proper, improper, equivalent, operations
- Decimals — fractions to decimals conversion
- Objectives of teaching Maths — Cognitive, Affective, Psychomotor
- NCF 2005 के मुख्य recommendations for Maths
Example: 47,352 में 7 का स्थानीय मान = 7,000
In 47,352 → 7 is in thousands place → its place value = 7,000.
Face value of 7 = always 7 (regardless of position).
| Type / प्रकार | Definition / परिभाषा | Example |
|---|---|---|
| Proper Fraction उचित भिन्न | Numerator < Denominator (अंश < हर) | 3/4, 2/7, 5/9 |
| Improper Fraction विषम भिन्न | Numerator ≥ Denominator (अंश ≥ हर) | 7/3, 9/4, 5/2 |
| Mixed Number मिश्रित संख्या | Whole number + proper fraction | 2¾, 3½, 5⅔ |
| Equivalent Fractions समतुल्य भिन्न | Same value, different numerator/denominator | 1/2 = 2/4 = 3/6 = 4/8 |
| Simplest Form सरलतम रूप | HCF of numerator and denominator = 1 | 4/6 → 2/3 (÷2) |
📐 Key Formulas — Number System
| Objective Type | Hindi / हिंदी | Examples in Maths |
|---|---|---|
| Cognitive / संज्ञानात्मक | ज्ञान, समझ, application, analysis | Solving equations, understanding proof, applying formulas |
| Affective / भावात्मक | Attitude, appreciation, values towards maths | Developing interest in maths, reducing maths anxiety |
| Psychomotor / मनोगात्मक | Physical/skill-based — drawing, constructing | Drawing geometric figures with compass/ruler, using abacus |
| NOT an objective ⭐ | "Educational" is NOT one of the 3 domains of objectives. PSTET directly asks this — answer = "Educational" is not an objective of teaching maths. | |
यह most frequently asked pedagogy fact है।
• Maths should connect to daily life
• Child-centred learning
• Problem-solving approach
• Fear of Maths कम करना
• Mathematics should be meaningful, not just procedural
• Children should construct knowledge themselves
• Contextual learning from daily life
• Remove math phobia / anxiety
"Curriculum" is derived from Latin
Mathematical concepts development order: Experiences (III) → Drawing pictures (I) → Symbolic representation (II) → Language (IV) = III, I, II, IV
📌 Key Takeaways — Day 1
- Place value ≠ Face value. Face value of any digit is always that digit itself.Common student error: reading correctly but writing wrong = place value misconception
- Fractions types: Proper (3/4) | Improper (7/3) | Mixed (2¾) | Equivalent (1/2=2/4)LCM method for adding/subtracting fractions — always find common denominator first
- 3 objectives of teaching Maths: Cognitive + Affective + Psychomotor"Educational" is NOT one of the objectives — PSTET directly asks this!
- NCERT Maths textbooks = NCF 2005 recommendation (NOT NPE 1986)"Curriculum" word = derived from Latin language
- Concept development order = Experiences → Pictures → Symbolic → Language (III, I, II, IV)
Ratio, HCF, LCM + Bloom's Taxonomy
Ratio · Proportion · HCF · LCM · Bloom's 3 Domains · 6 Cognitive Levels
अनुपात, समानुपात, HCF, LCM + ब्लूम का वर्गीकरण
🎯 Learning Objectives
- Ratio — same unit में convert करके simplify करना
- Proportion — 4th proportional, mean proportional
- HCF और LCM — prime factorization method
- Bloom's Taxonomy — 3 domains और Cognitive के 6 levels
- Who classified each domain जानना
📐 Ratio Rules / अनुपात के नियम
Use: Simplifying fractions, dividing things equally
Use: Adding/subtracting fractions, finding common time
12 = 2²×3 | 18 = 2×3²
HCF = 2×3 = 6
12 = 2²×3 | 18 = 2×3²
LCM = 2²×3² = 36
| Domain / डोमेन | Classified By / वर्गीकरण | Focus / केंद्र |
|---|---|---|
| Cognitive / संज्ञानात्मक | Bloom (1956) | Thinking, knowledge, understanding — सोचने की क्षमता |
| Affective / भावात्मक | Krathwohl (1964) | Feelings, attitudes, values — भावनाएं |
| Psychomotor / मनोगात्मक | Simpson / Harrow | Physical skills, motor abilities — शारीरिक कौशल |
| Level | Cognitive Domain Level | Hindi | Example in Maths |
|---|---|---|---|
| 1 (Lowest) | Knowledge / ज्ञान | याद करना | Recall formula of area of triangle |
| 2 | Comprehension / बोध | समझना | Explain why area = ½ × b × h |
| 3 | Application / प्रयोग | उपयोग करना | Solve: area of triangle with b=6, h=4 |
| 4 | Analysis / विश्लेषण | विश्लेषण करना | Compare different methods of solving |
| 5 | Synthesis / संश्लेषण | नया बनाना | Create a new problem using the concept |
| 6 (Highest) | Evaluation / मूल्यांकन | निर्णय करना | Evaluate which solution method is best |
"Cognitive domain objectives classification किसने दिया?" → Bloom
"Affective domain को subgroups में कब divide किया?" → Krathwohl, 1964
"Domains of Educational Objectives की संख्या है?" → 3 (Three)
"SOLO stands for?" → Structure of Observed Learning Outcome
📌 Key Takeaways — Day 2
- Ratio — ALWAYS convert to same unit first before calculating9/9 papers में ratio आया — यह मत छोड़ें। 75 paise : 4 rupees = 75:400 = 3:16
- HCF with ratio: Numbers = HCF × ratio parts. (HCF=12, ratio=1:2:3 → 12, 24, 36)LCM = for adding fractions | HCF = for simplifying fractions
- 3 Domains: Cognitive (Bloom, 1956) | Affective (Krathwohl, 1964) | PsychomotorCognitive domain के 6 levels: Knowledge → Comprehension → Application → Analysis → Synthesis → Evaluation
- SOLO = Structure of Observed Learning Outcome
- Greatest ratio: convert to decimals and compare. Ratio > 1 means numerator > denominator.
Geometry + Teaching Methods
Triangles · Angles · Area · Perimeter · Inductive vs Deductive · Abacus
ज्यामिति एवं क्षेत्रमिति + गणित शिक्षण की विधियाँ
🎯 Learning Objectives
- Triangle types — by sides और by angles
- Triangle angle sum property (180°)
- Area and Perimeter of basic shapes
- Euclid — Father of Geometry जानना
- Inductive vs Deductive method of teaching Maths
- TLM — Abacus, 3D resources for geometry
Father of Mathematics (broadly) = Pythagoras
"Mathematics" word coined by = Pythagoreans
| Triangle Type | By Sides (भुजाओं के आधार पर) | By Angles (कोणों के आधार पर) |
|---|---|---|
| Equilateral / समबाहु | All 3 sides equal | All angles = 60° |
| Isosceles / समद्विबाहु | 2 sides equal | 2 base angles equal |
| Scalene / विषमबाहु | All 3 sides different | All 3 angles different |
| Acute / न्यूनकोण | — | All angles < 90° |
| Right / समकोण | — | One angle = 90° |
| Obtuse / अधिककोण | — | One angle > 90° |
📐 Key Geometry Formulas
| Method | Hindi | How it works | Maths Example |
|---|---|---|---|
| Inductive Method ⭐ | आगमन विधि | Specific examples → General rule. Child discovers pattern. Observation → Generalization | Show 3+5=8, 7+5=12, 9+5=14 → Child discovers "adding 5 pattern" |
| Deductive Method | निगमन विधि | General rule → Specific examples. Teacher gives formula first. Criticized: mechanical practice, little attention to meaning. | Teacher gives formula, students apply. Rote-learning tendency. |
| Analytic Method | विश्लेषण विधि | Start from unknown (what to find) → work backwards to known | Given area, find side of square: A=s² → s=√A |
| Synthetic Method | संश्लेषण विधि | Start from known → reach unknown. Opposite of analytic. | Given side, find area: s=5 → A=25 |
| Heuristic Method | खोज विधि | Student discovers by themselves with minimal guidance | Let child figure out area formula by counting squares on graph paper |
Teaching aids most used in: Arithmetic (not Algebra, not Calculus). TLMs are most practically used in Arithmetic teaching.
📌 Key Takeaways — Day 3
- Father of Geometry = Euclid | "Mathematics" word = coined by PythagoreansTriangle angle sum = 180°. If two angles known, third = 180 − sum of two
- Heron's formula: s = (a+b+c)/2, Area = √[s(s-a)(s-b)(s-c)]Area of triangle = ½ × base × height — simpler formula for right/given height triangles
- Inductive = Specific→General (examples first) | Deductive = General→Specific (formula first)Deductive method criticized: mechanical, little meaning, isolated practice — ALL of these
- TLM most used in Arithmetic | Abacus = best tool for decimal addition (Class III)3D geometry resources: Tennis ball, Room, Cylindrical rod — all are valid
Simple Interest, Percentage + Diagnostic Test
SI Formula · Profit-Loss · Percentage · Diagnostic & Remedial Teaching in Maths
साधारण ब्याज, लाभ-हानि, प्रतिशत + निदानात्मक परीक्षण
🎯 Learning Objectives
- SI formula — Principal, Rate, Time की calculation
- Amount = Principal + SI
- Profit-Loss percentage formula
- Percentage problems — finding X% of Y
- Diagnostic Test importance in Maths (3 uses)
- Remedial Teaching — best feedback strategy
📐 Simple Interest Formulas
📐 Percentage Formulas
1. शिक्षण में (In teaching)
2. परामर्श और मार्गदर्शन में (In counseling)
3. उपचारात्मक शिक्षण की व्यवस्था में (For remedial teaching)
→ तीनों सही हैं — All of the given options ✅
1. In teaching — to understand student's current level
2. In counseling and guidance — identify needs
3. For remedial teaching arrangements
→ All three = correct. PSTET answer = "All of the given options"
• Case history or interview
• Clinical observation
• Informal testing
→ तीनों valid methods हैं। "None of the above" सही answer है (मतलब सब सही हैं)
Case history/interview ✓ | Clinical observation ✓ | Informal testing ✓
→ PSTET: "Which is NOT a method?" → Answer = "None of the above" (all listed ARE valid methods)
→ Each student checks their own answers (self-evaluation) — fastest and most effective for immediate feedback
1. Diagnostic test दो → 2. Specific error identify करो → 3. Different method से reteach करो → 4. Practice दो → 5. Re-evaluate
Key: DIFFERENT method — same method repeat करना = same result
📌 Key Takeaways — Day 4
- SI = PRT/100 | Amount = P + SI. Find P, R, or T by rearranging.PSTET SI type: Find Rate given two different time amounts → find SI per year first
- Proportionality: cross-multiply and solve for unknown additionAdd 2 to each of 2, 7, 10, 25 → 4, 9, 12, 27 → proportional (4×27 = 9×12 ✓)
- Diagnostic test importance = Teaching + Counseling + Remedial = ALL threeMethods of diagnostic test: Case history, Clinical observation, Informal testing — ALL valid
- When exam is near: Teacher should complete syllabus by extra time in school (NOT call students home)
Algebra + Symbol Interchange + Dyscalculia
Linear Equations · Symbol Problems · Patterns · Dyscalculia · Micro-teaching
बीजगणित, प्रतीक प्रश्न, अनुक्रम + अधिगम अक्षमता
🎯 Learning Objectives
- Symbol interchange problems — step-by-step approach
- Linear equations — one variable solve करना
- Number patterns — triangular and square numbers
- Dyscalculia — definition, symptoms, teaching strategies
- Micro-teaching — controlled practice system
- Gates के problem-solving steps
Replace each symbol with its new meaning, then solve normally. अर्थ बदलो, फिर normal calculate करो।
| Pattern Type | Hindi | Sequence | Formula |
|---|---|---|---|
| Triangular Numbers | त्रिभुजीय संख्याएं | 1, 3, 6, 10, 15, 21... | n(n+1)/2 |
| Square Numbers | वर्ग संख्याएं | 1, 4, 9, 16, 25, 36... | n² |
| Cube Numbers | घन संख्याएं | 1, 8, 27, 64, 125... | n³ |
| Fibonacci | फिबोनाची | 1, 1, 2, 3, 5, 8, 13, 21... | Each = sum of previous two |
Class 4 का Karan को numbers और calculations में problem है → Dyscalculia।
→ केवल Numbers (संख्या) — basic counting
HCF/LCM, Mensuration, Factors — नहीं सीख सकता (abstract concepts)
एक छोटे group में, limited time में, specific skill practice करना।
Gates द्वारा problem solving के steps बताए गए हैं।
(Exact number: PSTET में directly आया है)
📌 Key Takeaways — Day 5
- Symbol interchange: Replace symbols/numbers first → then apply BODMAS normally7/9 papers में आया — यह type practice करना बहुत ज़रूरी है। हर paper में 2-3 ऐसे questions होते हैं।
- Algebra pattern: Oranges = 4x + 15. "Remaining" = added outside the groupsLinear equation pattern: Set up equation first, then solve. Common PSTET approach.
- Dyscalculia = Maths-specific difficulty, NOT low IQ (Karan Class 4 wala question = Dyscalculia)Pre-operational stage (Piaget, 2-7 yrs) = only Numbers can be taught, not HCF/LCM
- Micro-teaching = Controlled Practice की system (not uncontrolled, not wide topic)
- Triangular numbers: 1,3,6,10,15 → n(n+1)/2 | Square numbers: 1,4,9,16,25 → n²
Statistics + Full Maths Pedagogy
Mean · Median · Mode · Evaluation · Values of Maths · Mathematical Language
सांख्यिकी + गणित शिक्षाशास्त्र का पूर्ण पुनरावलोकन
🎯 Learning Objectives
- Mean, Median, Mode calculate करना
- Values of Mathematics — Utilitarian, Disciplinary, Cultural
- Mathematical language build करने के तरीके
- Evaluation — Broadest concept, bases of evaluation
- Triangular process of teaching — 3 focal points
- Place of Mathematics in curriculum
📐 Mean, Median, Mode Formulas
| Value Type | Hindi | Meaning | Example |
|---|---|---|---|
| Utilitarian / Practical | उपयोगितावादी मूल्य | Daily life में use — practical value | Calculating change, measuring, budgeting |
| Disciplinary | अनुशासनात्मक मूल्य | Develops systematic, logical thinking, discipline | Following steps, logical reasoning |
| Cultural | सांस्कृतिक मूल्य | Maths as part of human civilization — Vedic Maths | Aryabhata, Brahmagupta, Vedic Mathematics |
| Social | सामाजिक मूल्य | Cooperation, sharing, fairness through maths | Dividing resources equally |
| NOT a value ⭐ | Irrationalism (अतार्किकता) is NOT a major educational value of Mathematics — PSTET directly asks this! | ||
Evaluation includes measurement AND judgment.
Teaching Method शिक्षण की त्रिकोणीय क्रिया का केंद्र बिंदु नहीं है
Teaching Method is NOT a focal point — it's the process between the three, not a vertex. Direct PSTET question.
→ Daily life की भाषा से जोड़कर, concrete experiences से, और gradually abstract symbols की तरफ बढ़ाकर।
Geography, Economics, Commerce, Life Sciences — सब से।
→ Topological Structure (संस्थानिक संरचना)
• "Most desirable teacher quality?" → Explain difficult aspects as simply as possible
• "Teacher's function?" → Teaching and learning (not just teaching)
• "Math teacher function?" → Teaching and learning (D — "teaching and learning" always preferred over "just teaching")
• "Good learning habits — what's desirable?" → Firm determination and initiative of learner
• "Mathematics is a part of?" → Geography, Economics, AND Commerce (all three)
📌 Key Takeaways — Day 6
- Mean = Sum/n | Median = middle value (arranged) | Mode = most frequentEven number of values: Median = average of 2 middle values
- Values of Maths: Utilitarian + Disciplinary + Cultural + Social. Irrationalism = NOT a value.Broadest concept: Evaluation > Measurement > Examination (Evaluation is most comprehensive)
- Evaluation basis = Objectives (not teaching aids, not lesson plans)Test discrimination < 0.30 = cannot differentiate low and high achievers
- Triangular process focal points = Teacher, Pupil, Contents. Teaching Method = NOT a focal point.Topological structure = limit and neighborhood concepts
- Maths is part of Geography + Economics + Commerce (all three)
