Year 4 · Selective School and Opportunity Class

Year 4 Mathematical reasoning practice for selective school tests

Selective and Opportunity Class questions are not harder arithmetic — they are ordinary arithmetic wrapped in a puzzle. The work is in seeing the structure: which quantity depends on which, and what would happen if one of them changed.

What the section covers

Number puzzles
Working backwards from a result, filling in missing digits, problems with more than one unknown.
Patterns and sequences
Finding the rule, extending it a long way, describing it in words.
Measurement and space
Area and perimeter in unfamiliar shapes, nets and folding, reading diagrams closely.
Logic in numbers
Deciding what must be true, what could be true, and what cannot be true at all.

Sample questions

8 real questions from our Year 4 papers, covering the different ways this section asks things. Answer the ones you can click; the rest show how they work. Nothing to sign up for.
