Spatial Sense 2
Project Description: Spatial Sense 2 in the Grade 4 math curriculum focuses on understanding geometric properties and spatial relationships. This unit aims to help students describe and represent shapes, locations, and movements using various geometric concepts.
Objective: The objective is to develop students' ability to navigate the world around them by applying geometric properties and understanding spatial relationships.
Driving Question: How can we use our knowledge of geometry and spatial sense to understand and describe the world around us?
Outcome: Students will be able to plot and read coordinates in the first quadrant of a Cartesian plane, describe and perform translations, reflections, and rotations, and identify the properties of tessellating shapes.
Main Subsections:
Plotting and Reading Coordinates:
Expectation: E1.2 Plot and read coordinates in the first quadrant of a Cartesian plane, and describe the translations that move a point from one coordinate to another.
Sample Problem: Plot the points (2,3), (4,5), and (6,7) on a Cartesian plane and describe the translation needed to move the point (2,3) to (4,5).
