Question 1

What makes a good odd-one-out task?

Accepted Answer

A good odd-one-out has at least two defensible answers — so pupils have to argue for a rule, not memorise a fact. The best examples are ones where the "correct" answer surfaces a useful category boundary or misconception.

Question 2

How do I use odd-one-out in a primary classroom?

Accepted Answer

Project four items, give pupils 2 minutes silent think, then 3 minutes paired discussion, then take answers and force justification. Total: 10 minutes, ideal for a starter. Pupils' rules will surface misconceptions you can address immediately.

Question 3

Is odd-one-out a retrieval task or a discussion task?

Accepted Answer

Both, depending on use. As a retrieval task: pupils must recall enough about each item to find a discriminating property. As a discussion task: pupils articulate and defend a category rule.

Question 4

Does Chalk generate the explanations or do pupils write them?

Accepted Answer

Both options. Chalk can generate the "correct" answer plus reasoning for teacher reference, or leave the explanation blank for pupils to construct.

Question 5

Is the odd-one-out tool free?

Accepted Answer

Yes. Free for teachers, with a small footer credit on free-tier exports. Pro removes the credit and unlocks unlimited generations.
