As you begin planning lessons for the new school year, you may want to take a look at the Teaching Channel. The website offers free videos of teachers in the classroom delivering effective lessons to their students. You can watch the teachers' interactions with their classes as well as brief interviews with the teachers and students. The Teaching Channel has videos for all the core subjects at a variety of grade levels, including great math lessons. 

One featured video shows Ms. Warburton teaching her algebra class about "mixture problems." In one example, students start with 8 liters of a 25% saline solution and some 70% saline solution.  The question is: How many liters of the 70% solution should you add to the 25% saline solution to get a 40% saline solution?  To help her students get a handle on this challenging question, she first makes a physical mixture of two colored liquids to illustrate how the weaker solution dilutes the stronger one. Then she walks the students through a "Mixture Picture," so they can organize the information more clearly.  Finally, Ms. Warburton introduces the "See Saw" method as another way for students to visualize the information and solve the problem. 

This video offers inspiring math teaching ideas, and there are many more available. The site includes PDFs of supporting materials and a discussion board for other educators to provide feedback about the videos and share their own ideas. The Teaching Channel is a great back-to-school resource. Do you have a favorite teaching video?
