  1. Math Operational Terms University of Texas/TSC Brownsville Prepared by Dr. Elva Cerda Pérez

  2. Mathematical OperationalTerms

  3. Patterns • A pattern is a model to be copied or a design from which to work. • Example: (Pattern) Source: New Concise Webster’s Dictionary, 1990 Edition

  4. Estimation • Estimation presents students with another dimension of mathematics; terms such as about, near, closer to, between, and a little less than illustrate that mathematics involves more than exactness. • Example: Without counting, estimate which has less than 5 and which has more than 5. 5 Source: 1989 NCTM Standards: Grades K-4 Standards 5: Estimation http://standards.nctm.org/previous/currevstds/k4s5.htm

  5. Drawing Pictures • Drawing pictures are natural ways that students communicate their mathematical investigations from early childhood through 2nd grade. • Example: A child’s notation for 10½. Source: 1989 NCTM Standards: Grades K-2 Communication http://standards.nctm.org/document/chapter4/comm.htm

  6. Concrete Representations: Models • Representations are more powerful tools for thinking; they make mathematical ideas more concrete and available for reflection. They support and extend reasoning by helping students focus on essential features of the mathematical situation. • Example: 1 + 1 = 2 (Using cubes) += Source: Principles and Standards http://www/nctm.org/tcm/2001/01/p288.htm

  7. Graph • A graph is the set of all points that correspond to the ordered pairs that satisfy that equation • Example: Source: Math Dictionary http://kidsmath.about.com/.../bldictionary.htm?terms=math+dictionary

  8. Numbers • Numbers are the total count of aggregated units or the symbol that stands for this amount. • Example: (3) Source: New Concise Webster’s Dictionary, 1990 Edition

  9. Numeration • Numeration is the act, art, or method of expressing or reading off numbers set down in numerals, especially those written decimally. • Example: Counting with an abacus. Source: Ato Z Dictionary Wysiwyg:/44/http://www.infoplease.com/ipd/A0562528.html

  10. Critical Thinking in Math • Critical thinking is the central to inquiry and application and should be interwoven throughout the mathematics curriculum to provide a context for learning and applying mathematical ideas. • Example: Try to make a hexagon with different shapes of manipulatives. Source: Grades 6-8: Problem Solving http://standards.nctm.org/document/chapter6/prob.htm

  11. Guessing and Checking • To form a judgment or estimate of (something) without actual knowledge or enough facts for certainty; to investigate in order to determine the condition, validity, etc. • Example: Guess how many bricks are there? Then, count them to check if you were right. Source: Webster’s New World. College Dictionary. Fourth Edition. New York (1999)

  12. Manipulatives • Manipulatives are important tools in helping student think and reason in more meaningful ways. By giving students concrete ways to compare and operate on quantities this contributes to the development of well-grounded understandings of mathematical ideas. • Example: The student will add 3 + 2 using bingo chips. + Source: Manipulatives: One Piece of the Puzzle http://www.cetm.org/mtms/2001/02/p356.htm

  13. National Council of Teachers of Mathematics Curriculum and Evaluation Standards • The National Council of Teachers of Mathematics Curriculum and Evaluation Standards provides guidelines for excellence in mathematics education and issue a call for all students to engage in more challenging mathematics. It is intended to be a resource and guide for all who make decisions that affect the mathematics education of students in prekindergarten through grade 12. • Example: • As teachers, we have to make sure to implement these standards in the curriculum. We have to be sure that our students are meeting the requirements that are needed to achieve the skills in math.

  14. Mathematical Tables • A systematic list of details, facts, numbers, etc. systematically arranged in columns or rows. • Example: Multiplication table Source: Billstein, R.et al. (1990). A Problem Solving Approach to Mathematics for Elementary School Teachers. Ed. The Benjamin/Cummings Publishing Co., Inc. 4th ed.

  15. Drawings in Math • A picture of the study of the relationships among numbers, shapes, and quantities made with a pencil, pen, or crayon. • Example: A drawings of a geometric shapes. Source: Webster’s New World. College Dictionary. Fourth Edition. New York (1999)
