Steps
Do this: Ask these out loud. Your child answers out loud; no paper needed.
- Ask: “4 × 9” Listen for: 36
- Ask: “2 × 4” Listen for: 8
- Ask: “5 × 3” Listen for: 15
- Ask: “5 × 5” Listen for: 25
- Ask: “4 × 5” Listen for: 20
Say this: “Split the space from 0 to 1 into equal parts. Each jump is one unit fraction.”
Say this: “Fractions can be greater than 1: 5/4 is past 1.”
Say this: “Number line: a line with numbers in order at equal spaces.”
Show: What fraction does the arrow point to?
Say this: “Each whole is cut into 6 equal parts, so each step is \tfrac{1}{6} .”
Say this: “The arrow is 5 steps from 0, so it points to \tfrac{5}{6} .”
Answer: \tfrac{5}{6}
Show: What fraction does the arrow point to?
Say this: “Each whole is cut into 4 equal parts, so each step is \tfrac{1}{4} .”
Say this: “The arrow is 2 steps from 0, so it points to \tfrac{2}{4} .”
Answer: \tfrac{2}{4}
Do this: Your child does these with you. Let them try first; help only after a real try.
Ask: What fraction does the arrow point to?
Listen for: \tfrac{1}{2}
If stuck: Each whole is cut into 2 equal parts, so each step is \tfrac{1}{2} .
Ask: What fraction does the arrow point to?
Listen for: \tfrac{2}{3}
If stuck: Each whole is cut into 3 equal parts, so each step is \tfrac{1}{3} .
Ask: What fraction does the arrow point to?
Listen for: \tfrac{2}{4}
If stuck: Each whole is cut into 4 equal parts, so each step is \tfrac{1}{4} .
7 more practice items on the lesson page, and on Worksheet A and Worksheet B.
- Counting the tick marks instead of the spaces.
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: Place fractions on a number line.
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.
