Instructions for Always, Sometimes or Never True Choose a statement. Try out different numbers. Write your examples on the statement card. 2. Conjecture: decide whether you think each statement is always, sometimes or never true. Always true: explain why on the poster. Sometimes true: write an example for which it is true and an example for which it is false. Never true: explain why on the poster.
