Decimals and fractions (age 11+)
Work interchangeably with terminating decimals and their corresponding fractions (such as 3.5 and 7/2 or 0.375 and 3/8); convert fluently between the two forms
Lesson
Set out your lesson
“Decimals and fractions (age 11+) 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
- Paper strips or a folded circle
- Pencil and labels (1/2, 1/4)
Extra for the adult
Worked example. Fold a strip in half: each piece is 1/2 of the whole.
Optional challenge. For Decimals and fractions (age 11+), add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Decimals and fractions (age 11+), not mastery.

Check understanding
- Convert any terminating decimal to a fraction in simplest form
- Convert any fraction with a denominator whose prime factors are only 2 and 5 to a terminating decimal
- Explain why some fractions produce terminating decimals and others do not
“If your child sees 0.375 on a calculator display, can they convert it to a fraction in its simplest form — without using the calculator?”
