Choosing the right strategy
Select and use appropriate tools and representations strategically, including choosing between mental methods, jottings, formal algorithms, and calculators for arithmetic with multi-digit numbers, decimals, and fractions
Lesson
Set out your lesson
“Choosing the right strategy 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 the right strategy, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Choosing the right strategy, not mastery.

Check understanding
- Choose a mental method for 345 + 200 but a written method for 345 + 278
- Select a ruler vs a metre stick based on the object being measured
- Decide when a number line is more useful than base-ten blocks for a given problem
“When your child faces a maths problem, do they think about which method suits it best — like doing easy ones in their head, using a written method for bigger calculations, or sketching a diagram for geometry?”
