Domain III: Mathematics Competency 016 (Mathematics Instruction)

1. 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.

2. Principles of Mathematics The NCTM identified six principles for school mathematics—equity, curriculum, teaching, learning, assessment and technology (2000). 1. Equity. Excellence in mathematics education requires equity‑high 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 student's learning.

3. 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.

4. 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, etc… • Avoid 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.

5. Remember…. We learn: • 10% of what we read • 20% of what we hear • 30% of what we see • 50% of what we both hear and see • 70% of what we discuss with others • 80% of what we experience personally • 95% of what we teach to someone else William Glasser

6. 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.

7. 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.

25. The Texas Essential Knowledge and Skills – TEKS – The Texas Essential knowledge and Skills (TEKS) requires a well‑balanced curriculum beginning in 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 one‑to‑one 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.

26. Mathematics curriculum for K-4 Kindergarten Whole‑number concepts and using, patterns and sorting to explore numbers, data and shapes First Adding and subtracting whole numbers and organizing and analyzing data Second Comparing and ordering whole numbers, applying additional and subtraction, and using measurement processes Third Multiplying and dividing whole numbers connecting fraction symbols to fractional quantities and standardizing language and procedures in geometry and measurement Fourth Comparing and ordering fractions and decimals, applying multiplication mid division and developing ideas related to congruence and symmetry

27. 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 (2‑1 1 years) (cited in Sperry Smith, 2001) Children in the Preoperational stage of cognitive development (2 - 7 years, Pre-K through grade 2) experience problems with at least two perceptual concepts - centration and conservation (Sperry Smith, 2001).

28. Cognitive Development and Mathematics Centration • Four and five‑year‑old children focus attention on one characteristic of an object and ignore the others. • They might notice that the objects are round, but fail to notice that they have different colors and texture. • Children at this age play with blocks in a very simplistic and systematic way-linear fashion. • They do not become more creative because they are emphasizing one feature at time. • Based on cognitive development, children at this age generally experience problems developing and recognizing patterns in mathematics.

29. Cognitive Development and Mathematics Conservation • Four and five‑years‑olds might not understand that changes in the appearance do not necessarily change characteristics of the object (Conservation). • This limitation can affect children's ability to measure volume and to understand the value of money. • That is, children might get confused when liquid is moved between containers of different shapes or when trying, to determine the value of a quarter versus five nickels. • These perceptual limitations can affect children's ability to understand measurement and the value of money.

30. Cognitive Development and Mathematics During the Concrete Operational stage of cognitive development second to seventh grades children experience rapid growth in cognitive development. This stage is characterized by the ability to think logically about concrete objects or relationships. Some of' the accomplishments of students at this stage are as follows: • Can form conclusions based Oil reason rather than Perception • Can arrange objects based oil characteristics (Classification) • Can organize objects based oil multiple criteria (Ordering or Seriation) • Call Understand that changes III appearance do not necessarily affect the substance (Conservation) • Can conceptualize what would have happened if an action is reversed (Reversibility)

31. Cognitive Development and Mathematics Despite the cognitive growth of this stage teachers have to structure lessons to provide students with a concrete foundation to support their thinking. For example, a teacher can introduce the concept of graphing by asking students to follow the growth of a plant for a period of time and document the growth using a Iine graph or to compare how one plant grows versus another plant using a bar graph. Teachers should also break down a task into manageable components with the use of graphic organizers (charts, diagrams, webs, time lines, etc.)

32. Piaget’s Levels of Cognitive Development Children evolve through specific stages in which cognitive structures become progressively more complex. Cognitive development refers to the changes that occur in an individual’s cognitive structures, abilities, and processes. Cognitive development is the transformation of the child’s undifferentiated, unspecialized cognitive abilities into the adult’s conceptual competence and problem-solving skill. Piaget believed children’s schemes, or logical mental structures, change with age and are initially action-based (sensorimotor) and later move to a mental (operational) level.

33. Piaget’s Levels of Cognitive Development Sensorimotor Stage (0-2 years) Intelligence develops through sensory experiences and movement. During the sensorimotor stage, infants and toddlers "think" with their eyes, ears, hands, and other sensorimotor equipment. Piaget said that a child’s cognitive system is limited to motor reflexes at birth, but the child builds on these reflexes to develop more sophisticated procedures. They learn to generalize their activities to a wider range of situations and coordinate them into increasingly lengthy chains of behavior. Learning involves pulling pushing, turning, twisting, rolling, poking, and interacting with many different properties of objects.

34. Piaget’s Levels of Cognitive Development Preoperational Stage (2-6/7 years) Intelligence includes the use of symbols such as pictures and words to represent ideas and objects. At this age, according to Piaget, children acquire representational skills in the area of mental imagery, and especially language. They are very self-oriented, and have an egocentric view; that is, preoperational children can use these representational skills only to view the world from their own perspective. Learning involves discovering distinct properties and functions of objects as they compare, sort, stack, roll, distinguish triangles from squares, and begin to use abstractions to communicate.

35. Piaget’s Levels of Cognitive Development Concrete Operational Stage (6/7-11/12 years) Cognitive development includes logic but requires physical examples to which the logic can be applied. They require experiences with touching, smelling, seeing, hearing, and performing. They must use hands-on tools to investigate. As opposed to preoperational children, children in the concrete operations stage are able to take into account another person’s point of view and consider more than one perspective simultaneously, with their thought process being more logical, flexible, and organized than in early childhood.

36. Piaget’s Levels of Cognitive Development Concrete Operational Stage (cont.) Children can also represent transformations as well as static situations. Although they can understand concrete problems, Piaget would argue that they cannot yet contemplate or solve abstract problems, and that they are not yet able to consider all of the logically possible outcomes. Children at this stage would have the ability to pass conservation (numerical), classification, seriation, and spatial reasoning tasks.

37. Piaget’s Levels of Cognitive Development Formal Operational Stage (11/12+ years) Thinking includes abstract concepts. This allows analytical and logical thought without requiring references to concrete applications. Persons who reach the formal operation stage are capable of thinking logically and abstractly. They can also reason theoretically. Piaget considered this the ultimate stage of development, and stated that although the children would still have to revise their knowledge base, their way of thinking was as powerful as it would get.

38. Piaget’s Levels of Cognitive Development Piaget suggest that there are four broad factors that are necessary and that affect the progression through these stages of cognitive development. They are • maturation • physical experience, • social interaction, and • equilibration. Clearly, learning experiences for children through the age of 12 must involve objects, tools, interaction, reflection, and social interaction with materials for optimal cognitive growth. The EC-4 teacher knows that mathematical concepts are best learned by children by manipulating materials and observing what happened-individually and collaboratively. A key to EC-4 mathematics is planning concrete experiences that facilitate learning. A sound mathematics classroom learning environment and curriculum reflect this cognitive approach to learning.
