Choosing mathematical tools
Select and use appropriate tools and representations strategically: choose between mental, written, and diagrammatic methods; use calculators for checking; select fraction models suited to the task
Lesson
Set out your lesson
“Choosing mathematical tools 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 Choosing mathematical tools, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Choosing mathematical tools, not mastery.

Check understanding
- Decide to use mental multiplication for 25×4 but a written method for 167×3
- Choose fraction strips rather than a number line to compare 3/8 and 1/4
- Use a ruler and squared paper to verify area by counting squares after calculating l×w
“When your child is working on maths, do they choose the right method — doing simple calculations in their head, using written working for complex ones, and sketching a diagram when a problem involves shapes or fractions?”
