Clip to ScrapBook #2

I know our 1st grade teachers all work on subitizing. I believe they do it as a warm-up activity with their students for much of the 1st half of the year. As students sit in a group, the teacher shows cards and students put their thumbs up to show they know the number. The teacher quickly calls on the students. The teachers move to having the pictures in more of an array or groups of objects so the students begin to transition from just the subitizing to adding the 2 numbers and "seeing" the larger number. The teacher asks the students how they saw their answer. Hope that helps!
