| A. Geometric Properties [4.2.3.A] |
|
- Identify and describe spatial relationships of two or more objects
in space.
- Direction, orientation, and perspectives (e.g., which object
is on your left when you are standing here?)
- Relative shapes and sizes
- Use properties of standard three-dimensional and two-dimensional
shapes to identify, classify, and describe them.
- Vertex, edge, face, side, angle
- 3D figures - cube, rectangular prism, sphere, cone, cylinder,
and pyramid
- 2D figures - square, rectangle, circle, triangle, pentagon,
hexagon, octagon
- Identify and describe relationships among two-dimensional shapes.
- Same size, same shape
- Lines of symmetry
- Understand and apply concepts involving lines, angles, and circles.
- Line, line segment, endpoint
- Recognize, describe, extend, and create space-filling patterns.
| B. Transforming Shapes [4.2.3.B] |
|
- Describe and use geometric transformations (slide, flip, turn).
- Investigate the occurrence of geometry in nature and art.
| C. Coordinate Geometry [4.2.3.C] |
|
- Locate and name points in the first quadrant on a coordinate
grid.
| D. Units of Measurement [4.2.3.D] |
|
- Understand that everyday objects have a variety of attributes,
each of which can be measured in many ways.
- Select and use appropriate standard units of measure and measurement
tools to solve real-life problems.
- Length - fractions of an inch (1/4, 1/2), mile, decimeter,
kilometer
- Area - square inch, square centimeter
- Weight - ounce
- Capacity - fluid ounce, cup, gallon, milliliter
- Incorporate estimation in measurement activities (e.g., estimate
before measuring).
| E. Measuring Geometric Objects [4.2.3.E] |
|
- Determine the area of simple two-dimensional shapes on a square
grid.
- Determine the perimeter of simple shapes by measuring all of
the sides.
- Measure and compare the volume of three-dimensional objects
using materials such as rice or cubes.
