standard_description: Recognize that sequences are functions, sometimes defined recursively, whose domain is a subset of the integers. For example, the Fibonacci sequence is defined recursively by f(0) = f(1) = 1, f(n+1) = f(n) + f(n-1) for n ³ 1.
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. The images used introduce students to the context that will be used throughout the lesson.
When students use the placement of objects in a 10-frame, they look for and make use of structure (MP7).

“Noah created this art. He used his fingerprints in a 10-frame and then decorated them like animals.”
“Today, we will make our own fingerprint animals using ink and our thumbs.”
