Three figures at the top belong together. The child finds the fourth that belongs with them, which means first working out what "belongs" means here: the shape, the number, the shading, the colour, or something less obvious. The reasoning happens before you ever look at the options.
No account needed. Fresh questions every time you press for five more.
Worth saying out loud the first few times. The order matters more than the speed.
Count, shape, colour, shading. Saying it converts a vague impression into a testable rule.
Whatever differs is not the rule. Usually this is position or rotation, and ruling it out prevents a whole class of wrong answers.
Describe what must be true: "three of them, dotted, six-sided." Do this before reading the options.
Take your list and knock out any option that fails on any single item. Do not weigh options against each other.

These are not guesses. They are what the wrong options in a real question are built from, which is why each one feels reasonable at the time.
The fix: If the three examples are tilted differently, tilt is deliberately irrelevant. What differs between examples can never be the rule.
The fix: The rule is usually two or three properties together. Write them all down before choosing.
The fix: Green and blue is a colour rule. Solid, striped and dotted is a shading rule. They are separate and both appear.
The fix: Count each option deliberately. Count is the property most often used to separate two otherwise identical options.
Three figures are shown that belong to the same group, and you choose a fourth that belongs with them. Unlike an odd one out, nothing is being excluded: you are identifying a rule from examples and then applying it.
Odd one out gives you a set and asks which member does not fit. Classification gives you a set that all fit and asks you to extend it. The reasoning is the same in both directions, but classification requires you to state the rule positively before you can answer.

Ask what is different between the three examples first, not what is the same. Differences are easier to see, and everything that differs can be crossed off the list of possible rules. What remains is usually the rule.
Typically two or three: for example three shapes, all dotted, all six-sided. The options are built so that each one satisfies most of the rule and fails on exactly one property, which is why a partial answer feels so convincing.
Count, then shape, then shading, then colour, works well because count and shape are the least ambiguous. Whatever the order, the point is to use the same one every time so nothing gets skipped under pressure.
One skill at a time is how you fix a weakness. A full timed test is how you find out whether it is fixed.
