## Reflection: Intervention and Extension Assessing Ability to Find Combinations of 10 - Section 2: Assessment Activity

I have 14 students in class today.  Thirteen of the students had no problem meeting the standard (of finding at least 5 combinations), and most found them all.  However, I have one student who has some solid thoughts but really struggles to organize her thoughts and record her thinking in an efficient way (for a variety of social and emotional reasons).

As I was circulating, I sat with her and worked with her on using cubes to build combinations and then to record her thinking with equations.  Although she did find 5 combinations, it was with assistance.  Therefore, I will be noting in her grade based on the assessment that she is nearing expectation but not quite there yet.

It was important to sit with her and build upon the knowledge she already had.  I could have treated it as a true assessment and offered no intervention.  However, this wouldn't have allowed me to see exactly what she could do and wouldn't have allowed her to have any success with the task.

There is a photo of her work in the section resource.  You can see how I had her erase what she had started and then started over.
