The purpose of this Number Talk is to elicit the strategies and understandings that students have for adding three 1-digit numbers within 20. When students look for ways to decompose addends to make a ten with another addend, and add the remaining addends to find the sum, they look for and make use of the structure of numbers and properties of operations (MP7).
