Reflection: Developing a Conceptual Understanding Greedy Gordy Visits the Bakery AGAIN!-Comparing Numerals 11-20 - Section 4: Independent Practice and Informal Assessment


This was an interesting lesson to teach.  Even though students in kindergarten only need to compare numerals through 10 according to the Common Core standards, I thought it would be good to challenge the students by going up to 20. 

It was really interesting for me to see the students who were able to apply what they know about numbers 0-10 to comparing numbers up to 20.  These students were able to quickly look at a pair of numbers and select the greater or lesser number.  They were able to apply their knowledge of numbers to larger numbers.  These students understand a great deal about "structure" and this knowledge will be used over and over again in tasks with increasing difficulty.

I did have two students who relied heavily on the number line for completing the independent practice.  I will need to find out why they needed the number line so much.  Did they not understand how to compare numbers 0-10? or Did they not understand how to apply this knowledge to larger numbers, so they defaulted to using the number line.  This will be something I will need to examine further.
