Equal Parts

• Fractions need equal parts — fair shares.
• Numerator (top) = parts we have; denominator (bottom) = total equal parts.
• Why unequal cuts do not make proper halves or quarters.
• Build fraction sense with Math Mela paper folding.

Level 1 — Core idea

Verbal: Split a rope into 3 equal lengths — each part is one-third.

Symbolic: In 3/5, 5 = equal parts in all; 3 = parts taken.

Visual: Circle with 4 equal sectors — shade 3 → 3/4.

Level 2 — Going deeper

Fold and cut to test equality. If one piece is bigger, it is not a fair fraction of the whole.

NCERT anchor

NCERT Math Mela, Class 3 — Chapter 10 stresses equal division before naming fractions. Always ask: "Are the parts the same size?"

A shape is cut into 3 parts but one is bigger. Can we call each 1/3?

Step 1 — Check equality: parts are **not** same size.
Step 2 — Rule: fractions need equal parts.
Answer: **No** — not fair thirds.

In 5/8, what do 8 and 5 mean?

Step 1 — Denominator 8 → whole split into **8 equal** parts.
Step 2 — Numerator 5 → **5** of those parts taken.
Answer: 8 equal parts; 5 shaded/taken.

• Label numerator and denominator in 2/6.
• Why must parts be equal?
• Is a pizza cut into 3 unequal slices showing thirds?
• Stretch: A strip folded into 6 equal parts — shade 4. What fraction?

Revision tip: Say aloud: "Out of __ equal parts, I have __" before writing the fraction.
