Steps
Do this: Ask these out loud. Your child answers out loud; no paper needed.
- Ask: “7 × 5” Listen for: 35
- Ask: “3 × 6” Listen for: 18
- Ask: “2 × 6” Listen for: 12
- Ask: “3 × 10” Listen for: 30
- Ask: “2 × 10” Listen for: 20
Say this: “Same denominator: compare the numerators. 5/8 > 3/8.”
Say this: “Same numerator: the smaller denominator is bigger. ⅓ > ⅕.”
Say this: “Compare: decide which is greater.”
Show: Write < or > : \tfrac{1}{2} ___ \tfrac{1}{4}
Say this: “Both have 1 part. Fewer cuts make bigger parts, so the smaller denominator wins.”
Say this: “\tfrac{1}{2} > \tfrac{1}{4}”
Answer: \tfrac{1}{2} > \tfrac{1}{4}
Show: Write < or > : \tfrac{1}{6} ___ \tfrac{1}{3}
Say this: “Both have 1 part. Fewer cuts make bigger parts, so the smaller denominator wins.”
Say this: “\tfrac{1}{6} < \tfrac{1}{3}”
Answer: \tfrac{1}{6} < \tfrac{1}{3}
Do this: Your child does these with you. Let them try first; help only after a real try.
Ask: Write < or > : \tfrac{5}{8} ___ \tfrac{7}{8}
Listen for: \tfrac{5}{8} < \tfrac{7}{8}
If stuck: The parts are the same size, so compare the numerators: 5 and 7.
Ask: Write < or > : \tfrac{3}{4} ___ \tfrac{1}{4}
Listen for: \tfrac{3}{4} > \tfrac{1}{4}
If stuck: The parts are the same size, so compare the numerators: 3 and 1.
Ask: Write < or > : \tfrac{1}{6} ___ \tfrac{5}{6}
Listen for: \tfrac{1}{6} < \tfrac{5}{6}
If stuck: The parts are the same size, so compare the numerators: 1 and 5.
7 more practice items on the lesson page, and on Worksheet A and Worksheet B.
- Thinking ⅕ is bigger than ⅓ because 5 is bigger.
Each player rolls a die (1–6) and takes that many sixths, or halves of that number in thirds. First to build one whole exactly wins.
Say this: “Tell me what you learned today. Show me with your hands or the counters if you like.”
Listen for: Compare fractions with the same denominator or the same numerator.
Fact drill (× and ÷) twice a week. Count by halves and fourths on the number line.
Spread over the week
5 sessions of 25–30 minutes. Stop while it is still going well.
- Session 1. Warm-up, then teach the new idea (steps 1 and 2).
- Session 2. Warm-up again, then show how with the examples.
- Session 3. Practice together, then play the game.
- Session 4. More practice on the worksheet, and the daily habit.
- Session 5. Quick check: narration and a few practice items. Move on when it is mostly right.
