## Reflection: Student Led Inquiry More Than Two Numbers - Section 3: Practice the Concept

I hadn’t yet taught the lesson about making a ten to add.  It was impressive to me that many students, while playing the game, realized that they could choose to add two numbers that make a ten first.

It prompted a great discussion about why it’s a good strategy and why it is helpful.  It was a great segue into my lesson for the following day.

Make Ten Surprise
Student Led Inquiry: Make Ten Surprise

# More Than Two Numbers

Unit 2: The Mission of Addition
Lesson 4 of 8

## Big Idea: The big idea of this lesson is that three (or more) numbers can be grouped together and added. The order of this grouping doesn't matter.
