Today, I gave Gracyn the chapter 1 test to understand her comprehension of the material covered thus far. Gracyn did very well, only missing 1 problem. She understood the concept of adding 0, using models to add to a group, the commutative property, and the corresponding vocabulary. We will move on tomorrow to Chapter 2 using these same concepts with subtraction. We spent the remainder of the lesson playing addition war together to practice fluency and speed.
