Math Vocabulary

Every term, the visual way. Each word comes with examples, a non-example, and often a short video—so students meet a concept by seeing it, not memorizing it. Find a term, project it, and let the noticing begin.

Introduce Any Term

Don’t lead with the definition—lead with the visual. Show the examples and non-example before the meaning, and let students build the word themselves.

1

Show, don’t define

Project the term with its examples and non-example. Hide the definition.

2

Notice & wonder

Ask: what do you notice? What makes the examples different from the non-example?

3

Describe it

Students try to put the meaning into their own words—then discuss as a class.

4

Reveal the definition

Now show the real definition. Play the video to lock it in.
