## Reflection: Intervention and Extension Written Form - Section 4: Closing

To provide an intervention for two students who needed extra support, I asked them to come up to the front white board while other students worked independently on the final task. They loved being able to write on the "teacher's whiteboard." The following videos document the gradual development of their place value understanding.

In this first video, the students begin by representing numbers from the same practice page that all other students were working on during this time.

In this video, I noticed that both students were successful with changing numbers from written form to standard form when the numbers didn't have any zeros.

Here, I increase the complexity of the task by giving the students numbers with zeros.

In this last video, I gave the students even larger numbers with zeros. When I gave the students the last task one of the students said, "This is fun! I wish I could do this the rest of the day!" That's when you know you're providing a successful intervention!
