This month, I am featuring some of my favorite websites for critical thinking and problem solving. Check back each Thursday for this special Thursday Tool School feature. Happy Surfing!
Last week, I shared an awesome resource to help students scrutinize a set of objects for their similarities and differences and then justify Which One Doesn’t Belong? Read the post here! The second website I want to share is one that I also shared a while back, it’s called Estimation 180. This website includes a plethora of images from the real world where students have to estimate a quantity in regards to what is represented in the picture. For an example, see the picture below.
Here’s how it works:
1. Choose an image.
2. For each image, have students answer the following questions:
- What estimate is too low?
- What estimate is too high?
- What is your estimate?
- What is your reasoning? Begin with, “I noticed . . .”
