Reflection: Developing a Conceptual Understanding Well...That's Puzzling! 11 - 20 - Section 2: Direct Instruction


Common Core State Standards require that kindergarten students be able to identify the components in a "teen" number (11-19). The purpose of this is to develop a place value understanding.

If we can grow our students understanding that a "teen" number is actually one ten and extra ones, as they learn about numbers, then developing understanding that 20 is actually two tens is a natural next step.

Having students memorize information rather than understand what they are learning is detrimental and will work against them for their entire academic career. On the other hand, building a conceptual understanding on how numbers work will allow them to understand complex manipulation of numbers in higher grades.
