## Reflection: Connection to Prior Knowledge Making Change using Partners of One Hundred - Section 2: Teaching the Lesson

In this lesson students are relating several things we have already touched upon. I do my best early in the lesson to help students make that connection. I want the connection to be obvious. We can hope that students will make the connection on their own, but often that is not the case. Many students see everything as new unless we build the bridges for them. This is especially true for those children who have more trouble with mathematical concepts. They do not automatically realize that what they are learning today has any relation to what they learned yesterday.

I make the bridges between what we have already talked about, to the new material very obvious. I often say, "remember how we...," or "yesterday we ...., do you remember?" In this lesson I made visual and auditory connections to prior experience by describing and using the balance scale for making change, and with counting back by tens.
