problem_activity: Narrative
The purpose of this How Many Do You See is for students to subitize or use grouping strategies to describe the images they see.
When students use grouping strategies to visualize the quantities in the
\(10 + n\)
structure they come to see that some can be taken from one group and added to the other to make a ten and some more (MP7).
Launch
Groups of 2
