Lesson objective: Understand that objects in our environment can be described using positional words (above, below, beside).

This is a student's first formal introduction to the new topic naming the location of an object or shape as students use positional words to describe objects in a familar environment. A conceptual challenge students may encounter is the use of specific vocabulary to describe location.

The concept is developed through work with familar objects, which provides the foundation for the transition to conceptual understanding using shapes.

This work helps students deepen their understanding of equivalence because an object's quantity remains the same regardless of position in the enviroment (extending one to one correspondence).

Students engage in Mathematical Practice 3 (Construct viable arguments and critique the reasoning of others) as they defend their choice describing object location.

**Key vocabulary:**

- above
- below
- beside
- next to

**Special materials needed:**

- Positional word arrows
- Positional word shape cards (example attatched in additional materials)
