The same four steps that make number talks work. Timing, prompts, and projection mode are handled for you.
A quick image appears just long enough to see, not count, so students reason about quantity instead of counting by ones.
The image hides. Quiet think time lets every student form an answer before anyone speaks.
"How did you see it?" A rotating prompt invites students to share the strategy behind their answer.
The image returns, often animated, to confirm the answer and make the strategy visible to the whole class.
