Statements and Truth Values

Statements and Truth Values

What students learn

Students learn to tell whether a sentence is a statement and whether that statement can be labeled true or false. Start with Truth Values Start With Clear Statements to hear the distinction in simple language.

Why it matters

Logic starts with careful reading. Negation Flips a Statement's Truth shows how changing one word can change the whole value of a claim.

Learn the idea

Students also learn to combine ideas with and and or. And and Or Combine Ideas Carefully helps them track more than one condition at once.

Try it

Give the student a list of short sentences such as "7 is prime," "Open the door," and "2 is even and 3 is even." Ask them to sort each one into statement, not a statement, true, or false, and explain why.

Parent guide

Keep the talk concrete and quick. If the student gives an answer without a reason, ask what part of the sentence makes it true, false, or not a statement at all.
