## Reflection: Developing a Conceptual Understanding Dot the Dog-Making Ten with Domino Patterns - Section 1: Opening

This lesson touches on several of the Common Core standards.  In creating this lesson, I was think of different approaches to help children better understand the standards around creating ten.  As I was creating this lesson, I was thinking of my own daughter.  She has struggled with addition and subtraction.  I think this is directly related to the instructional approaches in mathematics she experienced during her foundational years in school.  My daughter never really got to the point of "conceptualization".  She mastered memorization, but never really understood what those numbers meant.

As kindergarten teachers, we must help our students conceptualize "ten".  They should be able to break this number apart in every possible way.  Subtizing is such an important skill, but many math series do not provide adequate instruction for students.  The math series I previously taught from had students work with manipulatives and representations of numbers for ONE day and then it quickly moved to memorization.  A lot of key learning was skipped.  A true understanding of numbers takes time to acquire and as teachers, we must be patient and not rush the process.  The time spent on the front end will come back many times over.
