Standards addressed in this module:
Praxis:
Mathematics Curriculum, Instruction, and Assessment
Teaching strategies and activities that will aid in the development, delivery, and evaluation of the following:
- Rational numbers – for example, fraction and decimal equivalence; computation; modeling
- Curriculum components – for example, scope and sequence of skills and materials; appropriate materials and technology; learner objectives
- Use of manipulatives and developmentally appropriate materials; variety and reliability
- Content specific pedagogy – for example, theories necessary for implementing a sound instructional program such as accessing prior knowledge, constructing knowledge, modeling, informal reasoning, graphic organizers
- Problem solving – for example, investigate and understand content;formulate problems from everyday situations; develop strategies applicable to a wide range of problems; verify and interpret results; build student confidence; identify and solve problems that are developmentally appropriate
Conceptual Knowledge and Procedural Knowledge
Demonstrate number sense and operation sense, that is, an understanding of the foundational ideas of numbers, number properties, and operations defined on numbers (whole numbers, fractions, and decimals).
- Order: demonstrate an understanding of order among whole numbers, fractions, and decimals
- Equivalence: demonstrate an understanding that a number can be represented in more than one way
- Numeration and place value: demonstrate an understanding of how numbers are named, place value, and order of magnitude of numbers
- Computation: perform computations; adjust the result of a computation to fit the context of a problem; identify numbers or information or operations needed to solve a problem
NETS:
Demonstrate the ability to:
- Use technology tools and information resources to increase productivity, promote creativity, and facilitate academic learning.
- Use content-specific tools (e.g., software, simulation, environmental robes, graphing calculators, exploratory environments, Web tools) to support learning and research.
- Use technology resources to facilitate higher order and complex thinking skills, including problem solving, critical thinking, informed decision making, knowledge construction, and creativity.
- Use technology to locate, evaluate, and collect information from a variety of sources.
- Observe and experience the use of technology in their major field of study.

Expected module outcomes:
The student will be able to:
- Access and evaluate an elementary level interactive website.
- Demonstrate competencies in integer, rational and real number operations.
- Explain the mathematical foundations of real number computational algorithms.
- Identify advantages and disadvantages of each method of delivery: text, hands-on manipulative and interactive educational sites.
Performance-based assessment of module outcomes:
Students will complete a module summary in an electronic journal based on comparisons of text, hands-on manipulatives, and interactive educational sites. This module summary will be used in the culminating unit activity (see Unit Overview).
