SQUARE ONE TV has three goals, outlined here for easy reference.
GOAL I. To promote positive attitudes toward and enthusiasm for mathematics by showing the following:
A. Mathematics is a powerful and widely applicable tool useful to solve problems, to illustrate concepts, and to increase efficiency.
B. Mathematics is beautiful and aesthetically pleasing.
C. Mathematics can be understood, used, and even invented by nonspecialists.
GOAL II. To encourage the use and application of problem-solving processes by modeling the following:
A. Problem Formulation
- Recognize and state a problem.
- Assess the value of solving a problem.
- Assess the possibility of solving a problem.
B. Problem Treatment
- Recall information.
- Estimate or approximate,
- Measure, gather data, or check resources.
- Calculate or manipulate (mentally or physically).
- Consider probabilities.
- Use trial-and-error or guess-and-check.
C. Problem-Solving Heuristics
- Represent problem: scale model, drawing, map; picture, diagram, gadget; table, chart, graph; use objects, act out.
- Transform problem: reword, clarify; simplify; find subgoals, subproblems, work backwards.
- Look for: patterns; missing information; distinctions in kinds of information (pertinent or extraneous).
- Reapproach problem: change point of view, reevaluate assumptions; generate new hypotheses.
D. Problem Follow-up
- Discuss reasonableness of results and precision of results.
- Look for alternative solutions.
- Look for, or extend to, related problems.
GOAL III. To present sound mathematical content in an interesting, accessible, and meaningful manner by exploring the following:
A. Numbers and Counting
- Whole numbers.
- Numeration: role and meaning of digits in whole numbers (place value); Roman numerals; palindromes; other bases.
- Rational numbers: interpretations of fractions as numbers, ratios, parts of a a whole or of a set.
- Decimal notation: role and meaning of digits in decimal numeration.
- Percents: uses; link to decimals and fractions.
- Negative numbers: uses; relation to subtraction.
B. Arithmetic of Rational Numbers
- Basic operations: addition, subtraction, division, multiplication, exponentiation; when and how to use operations.
- Structure: primes, factors, and multiples.
- Number theory: modular arithmetic (including parity); Diophantine equations; Fibonacci sequence; Pascal's triangle.
- Approximation: rounding; bounds; approximate calculation; interpolation and extrapolation; estimation.
- Ratios: use of ratios, rates and proportions; relation to division; golden section.
C. Measurement
- Units: systems (English, metric, nonstandard); importance of standard units.
- Spatial: length, area, volume, perimeter, and surface area.
- Approximate nature: exact versus approximate, i.e., counting versus measuring; calculation with approximations; margin of error; propagation of error; estimation.
- Additivity.
D. Numerical Functions and Relations
- Relations: order, inequalities, subset relations, additivity, infinite sets.
- Functions: linear, quadratic, exponential; rules, patterns.
- Equations: solution techniques (e.g., manipulation, guess-and-test); missing addend and factor; relation to construction of numbers.
- Formulas: interpretation and evaluation; algebra as generalized arithmetic.
E. Combinatorics and Counting Techniques
- Multiplication principle and decomposition.
- Pigeonhole principle.
- Systematic enumeration of cases.
F. Probability and Statistics
- Basic quantification: counting; representation by rational numbers.
- Derived measures: average, median, range.
- Concepts: independence, correlation; "Law of Averages."
- Prediction: relation to probability.
- Data processing: collection and analysis.
- Data presentation: graphs, charts, tables; construction and interpretation.
G. Geometry
- Dimensionality: one, two, three, and four dimensions.
- Rigid transformations: transformations in two and three dimensions; rotations, reflections, and translations; symmetry.
- Tessellations: covering the plane and bounded regions; kaleidoscopes; role of symmetry; other surfaces.
- Maps and models in scale: application of ratios.
- Perspective: rudiments of drawing in perspective; representation of three-dimensional objects in two dimensions.
- Geometrical objects: recognition; relations among; constructions; patterns.
- Topological mappings and properties: invariants.
