Reflection: Checks for Understanding Students as Teachers Part II - Section 1: Filming and Working


In this lesson, and in Part I, students not only had to complete the math assigned, they also had to teach the math. For me, this is a project based assessment. As I watch the students try to explain their thinking, I can get a picture of what they do grasp, and any areas where they may need additional help.

Asking a student to teach to another student forces them to try to put into words the things that they do automatically. 

When the child in the video breaks the number into hundreds, tens and ones, and records them correctly as 700 + 40 + 3, and then puts the number back together again, I can see that he has an understanding of expanded notation. He knows that the 7 in 743 stands for 700.

I use this lesson to assess understanding of various concepts relating to place value, addition and subtraction.
