## Reflection: Twinkie the Rabbit: Exploring the Number 12 - Section 4: Independent Practice and Informal Assessment

As my students are competing their independent practice, I really make a point of circulating around the room to check their understanding of the concept.  With just a quick glance, I can tell who has developed one-to-one correspondence and who is still struggling with this concept.

This time, I noticed something very unusual.  One of my students was completing his work.  I was watching him.  He was not counting out 12 vegetables.  He was counting how many vegetables were in the entire row.  He was then SUBTRACTING to figure out how many he needed to color in.  For example, he counted 16 carrots.  He then counted back 4 and colored in the 12 carrots he needed.  I was amazed!  I would not have known that he had such an advanced understanding if I had not taken the time to observe his work informally.  A formal assessment would probably not have revealed this advanced level of understanding.

Summative assessments give teachers valuable information about mastery of standards, but there is a great deal of information that can be gained from informal, formative assessments.  Independent practice is not just practice.  It opens a window of understanding about student learning that is not always observable through a summative assessment.
