The provisions of this written curriculum shall be implemented


§111.12. Mathematics, Kindergarten.

(a)  Introduction.



     (1)  Within a well-balanced mathematics curriculum, the

          primary focal points at Kindergarten are

          developing whole-number concepts and using

          patterns and sorting to explore number, data, and

          shape.

     

     (2)  Throughout mathematics in Kindergarten-Grade 2,

          students build a foundation of basic

          understandings in number, operation, and

          quantitative reasoning; patterns, relationships,

          and algebraic thinking; geometry and spatial

          reasoning; measurement; and probability and

          statistics. Students use numbers in ordering,

          labeling, and expressing quantities and

          relationships to solve problems and translate

          informal language into mathematical symbols.

          Students use patterns to describe objects, express

          relationships, make predictions, and solve

          problems as they build an understanding of number,

          operation, shape, and space. Students use informal

          language and observation of geometric properties

          to describe shapes, solids, and locations in the

          physical world and begin to develop measurement

          concepts as they identify and compare attributes

          of objects and situations. Students collect,

          organize, and display data and use information

          from graphs to answer questions, make summary

          statements, and make informal predictions based on

          their experiences.

     

     (3)  Problem solving, language and communication,

          connections within and outside mathematics, and

          formal and informal reasoning underlie all content

          areas in mathematics. Throughout mathematics in

          Kindergarten-Grade 2, students use these processes

          together with technology and other mathematical

          tools such as manipulative materials to develop

          conceptual understanding and solve problems as

          they do mathematics.

          subtracting whole numbers and organizing and

          analyzing data.

     

     (2)  Throughout mathematics in Kindergarten-Grade 2,

§111.17. Mathematics, Grade 5.

(a)  Introduction.



     (1)  Within a well-balanced mathematics curriculum, the

          primary focal points at Grade 5 are comparing and

          contrasting lengths, area, and volume of geometric

          shapes and solids; representing and interpreting

          data in graphs, charts, and tables; and applying

          whole number operations in a variety of contexts.

     

     (2)  Throughout mathematics in Grades 3-5, students

          build a foundation of basic understandings in

          number, operation, and quantitative reasoning;

          patterns, relationships, and algebraic thinking;

          geometry and spatial reasoning; measurement; and

          probability and statistics. Students use

          algorithms for addition, subtraction,

          multiplication, and division as generalizations

          connected to concrete experiences; and they

          concretely develop basic concepts of fractions and

          decimals. Students use appropriate language and

          organizational structures such as tables and

          charts to represent and communicate relationships,

          make predictions, and solve problems. Students

          select and use formal language to describe their

          reasoning as they identify, compare, and classify

          shapes and solids; and they use numbers, standard

          units, and measurement tools to describe and

          compare objects, make estimates, and solve

          application problems. Students organize data,

          choose an appropriate method to display the data,

          and interpret the data to make decisions and

          predictions and solve problems.

     

     (3)  Problem solving, language and communication,

          connections within and outside mathematics, and

          formal and informal reasoning underlie all content

          areas in mathematics. Throughout mathematics in

          Grades 3-5, students use these processes together

          with technology and other mathematical tools such

          as manipulative materials to develop conceptual

          understanding and solve problems as they do
