Comparing Numbers up to 100

Joyful Mathematics 2 — Fun with Numbers. Comparing scores and ordering roll numbers on a line follows the greater-than and less-than ideas in Fun with Numbers.

• To compare two numbers using >, <, and =.
• The rule: compare tens first, then ones if tens are equal.
• To order numbers from smallest to largest on a number line.

Verbal: Ask: Which has more tens? If tens are equal, ask which has more ones?

Symbolic: 47 < 52 because 4 tens < 5 tens. 63 < 68 because tens equal (6) and 3 < 8.

Level 1 — Compare tens first

• 47 vs 52 → compare 4 tens vs 5 tens → 47 < 52
• 63 vs 68 → same tens (6), compare ones: 3 < 8 → 63 < 68

Level 1 — Symbols

Level 1 — Number line tip

Numbers to the right are larger. 45 is right of 40.

Level 2 — Equal tens

If tens digits match, ones digit decides: 81 vs 87 → 1 < 7.

Level 2 — Indian context

Comparing scores in a kho-kho match (34 vs 41 runs) or mangoes sold at a stall.

Which is greater: 58 or 85?

Step 1 — Compare tens: 5 vs 8
Step 2 — 8 tens > 5 tens, so 85 > 58
Step 3 — Write: 58 < 85
Answer: 85 is greater

• Fill in: 64 ___ 46
• Arrange 71, 17, 77 from smallest to largest.
• Is 90 greater than 89? How do you know?

Stretch: Arrange these kho-kho scores from highest to lowest: 41, 14, 40, 44. Explain using tens first.

Revision tip: Draw a 0–100 number line and mark your roll number and a friend's — the number on the right is always greater.
