## Reflection: Developing a Conceptual Understanding The Pencil Present: Decomposing 5 - Section 2: Guided Practice

For a second, when I look out and I consider doing group work to help with the challenge, but I know that 2 groups won’t have anyone to help guide the rest of the group through this activity, and one of my 2 buddies who looks like he’s got it, will simply dominate his group if I attempt to make this a group activity today.

While the day was not entirely successful, even with some impromptu scaffolding and modeling, it was a great opportunity to see where we’re at with our understanding and help me know where we need to work during our Friday problem solving days. Sometimes, it’s disheartening to look out and realize that 2 kids grasp a concept, but the good news is that we have plenty of time for concept development and reteaching.
