My classes just finished working on their Triple Nine Wall Clocks and would like to share some of their solutions for getting the integers from one through twelve. They found several ways to find most of the clock numbers, and your students likely will also. They turned in their projects today. Once I’ve scanned and uploaded them, we’ll share some of these student projects in another post. Here are selected solutions:

Give this a try; I’m sure your students will increase their number sense and all of you will enjoy the experience!
