I forgot to insert the pictures of our first data gathering. Here’s the wall with the 5′ – 12′ distances measured out. We had 4 stations. That’s a yardstick on the wall!
Here are some pictures of the kids gathering their data. The farther you stand, the more you see! What would be the measure on the “y-intercept”???
(it would be the width of the tube, or 1.75 inches!)
Finally, here are a couple of pictures of the kids working together on their partner quiz. The conversation is what is so awesome, they’re justifying their answers, questioning their partners, helping each other understand. It’s awesome!
