Odd One Out Numbers Worksheet
How to think it through (Test every number): Check each number for a property: even/odd, prime (only two factors), square (4, 9, 16 …), or a multiple of 3, 4, 5 … 9. Find the property that three numbers share and one does not. Make sure no other property points at a different number — then that one is the odd one out.
