Two Truths and a Lie with Significant Figures

Recently, I had my physical science students work through a series of five stations that had them practicing various aspects of working with significant figures.  One of the stations instructed them to create two truths and a lie about significant figures on a sheet of construction paper.  

I thought I would share what some of my students came up with!

This one was a bit different than the rest, and my students deemed it to be extra tricky!

We found out that pencil on construction paper is impossible to read on the document camera!

This student also made things tricky for her classmates by writing the numbers out in words!

This student decided to write his in neon expo marker.  It's kinda readable.

We went over these one at a time to determine the lie as a last-minute review before our significant figures test.  It was a great chance to put my new document camera (affiliate link) to use!  I used the Ipevo Presenter software to project the image on my SMARTboard.  (You can read how I got a FREE document camera for my classroom here!)  If you wish you had an interactive whiteboard in your classroom, Ipevo is giving away interactive whiteboard systems to deserving teachers for free this month!  You can put in your request here.


  1. What a great idea! I'd love to know what your other stations were!
