Domain III:MathematicsCompetency 016(Mathematics Instruction),The teacher understands how children learn mathematical skills and uses this knowledge to plan,organize,and implement instruction and assess learning.,Principles of Mathematics,The NCTM identified six principles for school mathematicsequity,curriculum,teaching,learning,assessment and technology(2000).1.Equity.Excellence in mathematics education requires equityhigh expectations and strong support for all students.2.Curriculum.A curriculum must be coherent,focused on important mathematics,and well articulated across grades.3.Teaching.Effective mathematics teaching requires understanding of what Students know and need to learn,and then challenging and supporting them to learn it well.4.Learning.Students must learn mathematics with understanding,actively building new knowledge from experience and previous knowledge.5.Assessment.Assessment should support the learn of important mathematics concepts,and furnish useful information to both teachers and Students.6.Technology.Technology is essential in teaching and learning mathematics it influences the teaching of mathematics and enhances students learning.,Principles of Mathematics,Use various materials to teach skills and concepts.Use different instructional techniques.Have students explain skills and concepts.Allow students to see their progress(e.g.,records of performance).Teach the language of mathematics(e.g.,word walls,flash cards,etc.).Use a variety of cues to check for understanding(e.g.,thumbs up,color coded cards,happy face cards,etc.).Include concrete,representational,and abstract activities.Avoid over reliance on workbooks for dictating curriculum and providing practice opportunities.,Principles of Mathematics,(cont.)Use instructional approaches that will ensure comprehension and mastery of skills and concepts,such as cooperative learning,graphic organizers,use of manipulatives,etcAvoid excessive paper-and-pencil drill that serves merely as busy work rather than as a meaningful practice experience.Link new instructional knowledge to present knowledge.Show students-and have students explain-how mathematics is part of daily living.Teach mathematical skills and concepts within a problem-solving context.,Remember.We learn:,10%of what we read20%of what we hear30%of what we see50%of what we both hear and see70%of what we discuss with others80%of what we experience personally95%of what we teach to someone elseWilliam Glasser,How Do Children Learn Mathematics?,Research indicates that children must develop higher level thinking abilities in order to interpret certain mathematical concepts.Because the development of some of these abilities is so natural,teachers often fail to consider that children in certain stages of development may not have acquired them.To be an effective teacher you must know when children can be introduced to a given concept and at what level of abstraction they can deal with the concept.Basically there are three levels at which concepts can be represented:concrete,pictorial,and symbolic.,Levels of math development,Concrete Level.A concept can be represented by the appropriate manipulation of objects.Example:Placing three beans into each of four margarine tubs and finding the total number of beans illustrates that 4 X 3=12.Pictorial Level.A concept can be represented by appropriate pictures.Example:A picture of four groups of three to illustrate 4 X 3=12.Symbolic Level.A concept can be represented by symbols.Example:4 X 3=12.,Standard for Mathematics,The standards for mathematics are divided into two sections content and process.Content standardsProcess standards,Standard for MathematicsContent Standards,1.Number and

kindergarten and continuing through grade12.(TEA,2006)It incorporates the principles and standards of the NCTM and introduces these in a sequential manner that reflects the cognitive development of children.Children in kindergarten begin exploring number concepts using concrete objects and mastering onetoone correspondence.In first and second grades they continue exploring number concepts and begin studying basic computations skills.In third through fifth grades they continue expanding number concepts to include multiplication,division fractions,decimal representations,geometric principles and algebraic reasoning.,Mathematics curriculum for K-4,KindergartenWholenumber concepts and using,patterns and sorting to explore numbers,data and shapes FirstAdding and subtracting whole numbers and

and developing ideas related to congruence and symmetry,Cognitive Development and Mathematics,The cognitive development of children in Pre-Kindergarten(Pre-K)through grade 4 represents a special challenge when attempting to learn the symbolic and abstract representations used in mathematics.Piaget classified students in Pre-K through grade 4 into two broad stages:Preoperational(2-7 years),and Concrete Operational(21 1 years)(cited in Sperry Smith,2001)Children in the Preoperational stage of cognitive development(2-7 years,Pre-
