This Fluency Activity is a part of the Lesson 13, Unit 3, Grade K. The dot cards can be adjusted to facilitate the recognition of hidden numbers. Use dots in more than one color, or include some dots with only an outline. This can be used as a modification for students with visual discrimination difficulties, especially during partner sharing time. This activity deepens students' knowledge of embedded numbers and develops part-whole thinking, foundational to the work of the upcoming modules.
