Lesson objective: Understanding that objects in our environment can be described using positional words.

This is a new topic for students to work on learning, understanding, and applying positional word vocabulary to describe an object's location.

The concept is developed through work with familar enviromental settings, which connects new vocabulary with known understanding of settings.

This work helps students deepen their understanding of equivalence because an understanding of an object's position in our environment as described using positional words deepens student understanding of how many objects remain constant regardless of position.

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

**Key vocabulary:**

- above
- below
- beside
- next to

**Special materials needed:**

- Shape cards- circle, square, rectangle, triangle
- Arrow cards with positional words recorded on each (Suggested color equivalence, ie. blue arrow always refers to the positional word above)
