A. Geometric Properties

1. Identify and describe spatial relationships among objects in space and their relative shapes and sizes.
   • Inside/outside, left/right, above/below, between
   • Smaller/larger/same size, wider/ narrower, longer/shorter
   • Congruence (i.e., same size and shape)
2. Use concrete objects, drawings, and computer graphics to identify, classify, and describe standard three-dimensional and two-dimensional shapes.
   • Vertex, edge, face, side
   • 3D figures - cube, rectangular prism, sphere, cone, cylinder, and pyramid
   • 2D figures - square, rectangle, circle, triangle
   • Relationships between three- and two-dimensional shapes (i.e., the face of a 3D shape is a 2D shape)
3. Describe, identify and create instances of line symmetry.
4. Recognize, describe, extend and create designs and patterns with geometric objects of different shapes and colors.

B. Transforming Shapes

1. Use simple shapes to make designs, patterns, and pictures.
2. Combine and subdivide simple shapes to make other shapes.

C. Coordinate Geometry

1. Give and follow directions for getting from one point to another on a map or grid.

D. Units of Measurement

1. Directly compare and order objects according to measurable attributes.
   • Attributes - length, weight, capacity, time, temperature
2. Recognize the need for a uniform unit of measure.
3. Select and use appropriate standard and non-standard units of measure and standard measurement tools to solve real-life problems.
   • Length - inch, foot, yard, centimeter, meter
   • Weight - pound, gram, kilogram
   • Capacity - pint, quart, liter
   • Time - second, minute, hour, day, week, month, year
   • Temperature - degrees Celsius, degrees Fahrenheit
4. Estimate measures.

E. Measuring Geometric Objects

1. Directly measure the perimeter of simple two-dimensional shapes.
2. Directly measure the area of simple two-dimensional shapes by covering them with squares.
