In this unit, students will count and answer how many objects are in a line or a rectangular array, sort and count objects to identify how many are in a category, and find objects in the environment and describe the exact location of the objects using positional words (above, below, beside, etc.).

**Key Concepts:**

- We can count to answer how many objects are arranged in a line or a rectangular array. (Lesson 1)
- Objects can be sorted and counted to identify how many are in a category. (Lesson 4)
- Objects in our environment can be described using positional words (above, below, beside, etc.); (Lesson 7)

**Prior Knowledge Needed:**

- Rote counting and understanding amount counted (Kindergarten, Unit 1)
- Write numbers and count “How many?” within 10 (Kindergarten, Unit 2)
