standard_description: Directly compare two objects with a measurable attribute in common, to see which object has “more of”/“less of” the attribute, and describe the difference. For example, directly compare the heights of two children and describe one child as taller/shorter.
problem_activity: Narrative
The purpose of this warm-up is for students to experience a new part of the Questions About Us routine. Students consider concepts of number in a familiar context. This warm-up focuses on cardinality, or knowing that the last number tells us how many, and keeping track of which images have been counted. In the activity, students share methods for counting the images. After counting the group of images as a class or inviting a student to demonstrate how to count the images, ask students,  “How many students chose cats?” to confirm that students know that the last number tells us how many.
The images included in the Questions About Us Chart blackline master K.2.B are examples of what to display for the Questions About Us warm-ups in Section B. In order to create a display that will be visible to the whole class, print and cut out enough 5-frames so that there is a square for each student in the class. For example, if there are 23 students in the class, cut out four 5-frames and 3 squares out of a fifth 5-frame. Consider laminating the display and using a dry erase marker to write the two choices and record students' responses. If available, the provided images can also be enlarged.
