Odd One Out — questions

Can there be two right answers?

No. For the number sets, the computer checks every common property — odd and even, the 3 to 12 times tables, primes, squares, cubes and the number of digits — so that only one number can be called the odd one out.

What does the words level practise?

English words from the TalentJR Spoken English course grouped by meaning: animals, birds, colours, fruits, body parts, clothes, family, feelings, vehicles, toys and more.

Which level should my child choose?

Words for ages 6–9, easy numbers (odd/even, 5s and 10s) for 7–8, medium (tables 3–9, squares) for 9–11 and hard (primes and bigger tables) for 11+.

Is it free?
