A simple way through reasoning

The skills are different shapes of the same move. Odd one out asks what three things share before naming the fourth that is missing it; spot the error asks a child to follow someone else's working and find where it left the road; symbol puzzles hide the same number behind the same shape and ask them to read the structure back out. None of them can be answered by recognising the question and reaching for a remembered method, which is exactly why they are worth setting.

Why this order works

Always, sometimes, never and is-it-always-true are where proof begins. A single counterexample is enough to demote a claim from "always" to "sometimes", while no number of examples is ever enough to promote it — and a child who learns to try zero, one and a negative before answering has a method rather than a hunch. Number sequences run the same reasoning forwards and backwards: name the rule from the terms, then use it to find a term far down the line.
