Lesson 13
Fingerprint Animals (optional)
Lesson Purpose
Lesson Narrative
This lesson is optional because it does not address any new mathematical content standards. This lesson does provide students with an opportunity to apply precursor skills of mathematical modeling. This lesson builds on students’ previous understanding and experiences with writing and composing numbers 11–19.
In this lesson, students make a number book with pages of fingerprint animals for the numbers 11–19. They arrange the animals in a 10frame so that it is easy to see the number as \(10 + \boxed{\phantom{3}}\) and write matching equations like \(10 + 4=14\). Then they put the numbers in order and read the book together.
