Chapter 18

Measurement and Geometry: Measure, identify and draw angles,
perpendicular and parallel lines, rectangles, and triangles by
using appropriate tools (straightedge, ruler, compass, protractor) 
Mathematical reasoning: Apply strategies and
results from simpler problems to more complex problems. 
Mathematical reasoning: Use a variety of methods such as words, numbers,
symbols, charts, graphs, tables, diagrams, and models to explain
mathematical reasoning. 
Chapter 19

Measurement and Geometry: Know that the sum of the angles of any triangle
is 180º and the sum of the angles of any quadrilateral is
360º and use this information to solve problems. 
Measurement and Geometry: Measure, identify and draw angles,
perpendicular and parallel lines, rectangles, and triangles by
using appropriate tools (straightedge, ruler, compass, protractor) 
Measurement
and Geometry: Students identify,
describe, and classify the properties of, and the relationships
between plane and solid geometric figures. 
Mathematical reasoning:
Use a variety of methods, such as words, numbers, symbols, charts,
graphs, tables, diagrams, and models to explain mathematical
reasoning.

Chapter 21

Measurement and Geometry: Derive
and use the formula for the area of a triangle and of a parallelogram
by comparing them with the formula for the area of a rectangle. 
Measurement and Geometry: Students understand and compute the volumes and
areas of simple objects. 
Chapter 21

Measurement and Geometry: Construct
a cube and rectangular box from twodimensional patterns and
use those patterns to compute the surface area for these objects. 
Measurement and Geometry: Visualize
and draw twodimensional views of threedimensional objects made
from rectangular solids 
Measurement and Geometry: Students identify, describe, and classify the
properties of, and the relationships between plane and solid
geometric figures. 
Measurement and Geometry: Students understand and compute the volumes and
areas of simple objects. 
Measurement and Geometry: Understand
the concept of volume and use appropriate units in common measuring
systems to compute the volume of rectangular solids. 
Measurement and Geometry: Differentiate
between, and use appropriate units of measures for, two and
threedimensional objects. 
Mathematical reasoning: Express the solution clearly and logically
by using the appropriate mathematical notation and terms and
clear language; support solutions with evidence in both verbal
and symbolic work.
