These are printable response cards that can be laminated and even attached to rulers to make traffic-like signs.  If you’re conserving colored ink, I use these most often with group activities, and have about 5 or 6, rather than a whole class set.

Quick note: If you put another sheet of paper behind them before laminating, the reverse side is then available to write on with dry-erase markers if you want students to correct false statements or provide evidence or examples for their answers.
