Steps

Warm-up
Do this: Ask these out loud. Your child answers out loud; no paper needed.
- Ask: “12 × 2” Listen for: 24
- Ask: “2 × 12” Listen for: 24
- Ask: “5 × 3” Listen for: 15
- Ask: “9 × 4” Listen for: 36
- Ask: “6 × 5” Listen for: 30
Teach the new idea
Say this: “Equal parts make fractions.”
Say this: “Same numerator: smaller denominator, bigger fraction.”
Show how
Show: What fraction does the arrow point to?
$number line$
Say this: “Each whole is cut into 8 equal parts, so each step is \tfrac{1}{8} .”
Say this: “The arrow is 6 steps from 0, so it points to \tfrac{6}{8} .”
Answer: \tfrac{6}{8}
Show: Fill in the missing number: \tfrac{3}{4} = \tfrac{?}{12}
Say this: “The denominator went from 4 to 12: 4 × 3 = 12.”
Say this: “Multiply the numerator by 3 too: 3 × 3 = 9”
Say this: “\tfrac{3}{4} = \tfrac{9}{12}”
Answer: 9
Practice together
Do this: Your child does these with you. Let them try first; help only after a real try.
Ask: What fraction of the shape is shaded?
$bar in 4 equal parts, 1 shaded$
Listen for: \tfrac{1}{4}
If stuck: The whole has 4 equal parts.
Ask: What fraction of the shape is shaded?
$circle in 6 equal parts, 4 shaded$
Listen for: \tfrac{4}{6}
If stuck: The whole has 6 equal parts.
Ask: What fraction of the shape is shaded?
$circle in 3 equal parts, 1 shaded$
Listen for: \tfrac{1}{3}
If stuck: The whole has 3 equal parts.

Game: Fact Bingo
Fill a grid with products. Call out facts such as “7 × 8”. Cover the products. Four in a row wins.
Narration
Say this: “Tell me what you learned today. Show me with your hands or the counters if you like.”
Listen for: Review naming, placing and comparing fractions.
Daily habit
Fact drill daily. Goal: all × and ÷ facts to 12 × 12 in 3 seconds.
