## Reflection: Adjustments to Practice Word Problems with 3 Addends Part II - Section 2: Whole Group Interaction

You can see in the video that my students selected numbers to add that equaled 10 and thank goodness that was their choice. Next year, when I teach this lesson I will begin by reminding my students about the short cuts we have learned and focused on when adding. I have covered many strategies that build fluency in adding; adding zero, doubles facts, commutative property of addition, adding one, etc. I need to refresh their memory that here is a perfect opportunity to use these strategies and make those connections.
