In this unit...
Students will understand that...
Geometry and spatial sense provide a way to describe our physical environment.
Two and three dimensional objects can be described, classified, and analyzed by their attributes.
Measurement is the comparison of an attribute and a tool or system.
Objects, pictures, and numbers can be used to represent problem situations.
Measurement systems have increasing levels of precision.
Measurement systems are made up of relative measures within each system.
Students will keep considering the following questions
What geometric figures describe everyday objects?
How do we describe, sort, and classify 2-D and 3-D figures in more than one way?
How do I know what to measure? What tool, technique, or formula will I use?
How can I use objects and pictorial models to solve different types of problems?
How do I compare or combine objects to make sense of a problem?
How exact does a measurement have to be?
How do I convert measurement units to solve problems?
Students will know:
an attribute is a characteristic or component of a geometric figure.
attributes combine to form the properties of a figure.
formal geometric language is used describe shapes and solids.
geometric attributes can be used to classify and sort shapes and solids.
quadrilaterals can be represented different ways.
2-D shapes can be described by the number of sides and vertices.
3-D solids can be described by the number of faces, edges, and vertices.
the area of a figure is the number of square units needed to cover it exactly without gaps or overlaps.
capacity is the liquid volume a container can hold.
unit fractions with the same area do not have to have the same shape.
unit fractions have a one in the numerator.
measurement systems are made up of basic units and subordinate units (m, cm).
customary units of weight.
customary and metric units of capacity.
the area of complex shapes can be divided to help find the area of the whole figure.
Students will be skilled at:
sorting geometric figures using formal vocabulary, including edge, face, vertex
identifying and classifying 2-D figures by name or attributes
identifying and classifying 3-D figures by name or attributes (cone, sphere, cylinder, triangular prism, rectangular prism and cubes)
applying the mathematical process standards
drawing quadrilaterals that are not rhombuses, parallelograms, trapezoids, rectangles and square
finding the area by covering a rectangle with square units.
applying the mathematical process standards.
represent perimeter or area using models.
solving problems involving increments of time.
adding and subtracting increments of time using models and tools.
finding the missing side length of a polygon when perimeter and remaining lengths are given.
finding the perimeter of a figure.
