Standard 2.0 Knowledge of Geometry: Students will apply the properties of one-, two-, or three-dimensional geometric figures to describe, reason, or solve problems about shape, size, position, or motion of objects.
|
|
A. Plane Geometric Figures
|
1. Analyze the properties of plane geometric figures
|
a. Identify properties of angles using manipulatives and pictures
|
b. Identify, compare, classify, and describe angles in relationship to another angle
Assessment limit:
- Use acute, right, or obtuse angles
|
c. Identify parallel and intersecting line segments
|
|
B. Solid Geometric Figures
|
1. Analyze the properties of solid geometric figures
|
a. Identify cones, cylinders, prisms, and pyramids
Assessment limit:
- Use cones or cylinders
|
b. Describe solid geometric figures by the number of edges, faces, or vertices
Assessment limit:
- Use triangular pyramids, rectangular pyramids, triangular prisms, or rectangular prisms
|
2. Analyze the relationship between plane geometric figures and surfaces of solid geometric figures
|
a. Compare a plane figure to surfaces of solid geometric figure
Assessment limit:
- Analyze or identify the number or arrangement of squares needed to make a cube and triangles/rectangles needed to make a triangular pyramid or rectangular pyramid.
|
|
C. Representation of Geometric Figures
|
1. Represent plane geometric figures
|
a. Sketch acute, right, obtuse angles, and parallel and intersecting line segments
|
|
D. Congruence
|
1. Analyze geometric figures
|
a. Identify and describe geometric figures as congruent
Assessment limit:
- Identify the result in a transformation as being congruent to the original figure
|
|
E. Transformations
|
1. Analyze a transformation
|
a. Identify and describe the results of translations, reflections, and rotations
Assessment limit:
- Use a horizontal line translation, reflection over a vertical line, or rotation of 90° clockwise around a given point of a geometric figure or picture
