Lesson
Set out your lesson
“One Quantity as a Fraction means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.”
Bring to the table
- Tally sheet or simple bar/dot sketch
- A short set of category counts
Extra for the adult
Worked example. Cats 4, dogs 2 — cats have more. The tally and comparison are the proof.
Optional challenge. For One Quantity as a Fraction, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples One Quantity as a Fraction, not mastery.

One Quantity as a Fraction means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.
Materials: Tally sheet or simple bar/dot sketch; A short set of category counts. 1. Say the goal of One Quantity as a Fraction in plain words once. 2. Adult tallies one category and sketches a bar or dot plot. 3. Child tallies three small data sets and compares the tallest category. 4. Fresh check: one fresh tally comparison. Record and stop. Done: three correct tallies with a comparison sentence each. Proof: parent note of examples and results. Stop: End after the fresh check; keep optional challenge for another day.

Check understanding
- Express 45 minutes as a fraction of 2 hours (= 3/8)
- Express a larger quantity as a fraction of a smaller one and explain why the result exceeds 1
- Simplify the resulting fraction and interpret its meaning in the original context
“If there are 15 boys and 20 girls in a class, can your child express the number of boys as a fraction of the whole class and say whether that fraction is less than or greater than a half?”
