The "Spatial Sense" strand in Grade 4 focuses on developing students' understanding of geometric properties, spatial relationships, and measurements. This curriculum helps students navigate and interpret the world around them through geometry and measurement concepts.
Key Subsections
Geometric Reasoning (E1):
Identifying Geometric Properties: Students learn to identify geometric properties of rectangles, including the number of right angles, parallel and perpendicular sides, and lines of symmetry.
Constructing and Identifying Shapes: They practice constructing two-dimensional shapes and three-dimensional objects, emphasizing understanding their properties and relationships.
Symmetry and Congruence: Students explore concepts of symmetry and congruence by constructing and describing shapes and objects that have matching halves and identifying congruent shapes.
Sample Problem:
Identify the number of lines of symmetry in a given rectangle and describe the properties that make the rectangle symmetrical.

Measurement and Estimation (E2):
Using Appropriate Units: Students learn to use appropriate metric units to estimate, measure, and compare the perimeters of polygons and curved shapes.
Angles: Understanding different types of angles (right, straight, acute, and obtuse) and using tools like protractors to measure and construct angles.
Sample Problem:
Measure the perimeter of a triangle using a ruler and convert the measurements into different metric units.

Three-Dimensional Objects and Views:
Constructing and Visualizing Objects: Students are taught to construct three-dimensional objects and understand different views (top, front, and side) of these objects. They learn to match these views with the corresponding physical objects.
Sample Problem:
Draw the top, front, and side views of a given three-dimensional object and match these views to a physical model.

These components are designed to build a strong foundation in spatial reasoning, critical for understanding and interacting with the physical world. The curriculum integrates practical problems and visual aids to enhance comprehension and engagement.
