Sensorimotor Stage (Infancy) Pre-Operational Stage (Toddler to Early Childhood) Concrete Operational Stage (Elementary) Formal Operational Stage (Adolescence) Cognitive Development
Sensorimotor Stage (Birth – 2 yrs old) (Infancy) In this period, intelligence is demonstrated through motor activity without the use of symbols. Knowledge of the world is limited (but developing) because its based on physical interactions and experiences. Children acquire object permanence at about 7 months of age (memory). Physical development (mobility) allows the child to begin developing new intellectual abilities. Some symbolic (language) abilities are developed at the end of this stage. Cognitive Development
Pre-Operational Stage (2 – 7 yrs old) (Toddler to Early Childhood) In this period (which has two substages), intelligence is demonstrated through the use of symbols, language use matures, and memory and imagination are developed, but thinking is done in a nonlogical, nonreversible manner. Egocentric thinking predominates Can Not Think Of More Than One Thing At A Time! Cognitive Development
PK through 2nd Grade Centration Tendency to Focus on One Aspect of a Situation and Neglect the Other Aspects Focusing on Color Rather Than Shape When Grouping Blocks or Other Shapes Pre-Operational Stage
PK through 2nd Grade Lack Conservation Quantity, Length or Number of Items is unrelated to the arrangement or appearance of items. Nickel is more than a Dime Because of its Size Pre-Operational Stage
Concrete Operational Stage (7-11 yrs old) (Elementary) In this stage (characterized by 7 types of conservation: number, length, liquid, mass, weight, area, volume), intelligence is demonstrated through logical and systematic manipulation of symbols related to concrete objects. Operational thinking develops (mental actions that are reversible). Egocentric thought diminishes. Conservation & Reverse Thinking With Concrete Objects! Cognitive Development
2nd – 6th Grade Conservation Properties are conserved or invariant after an object undergoes physical transformation. A Stack versus a Row of Coins Beaker of Liquid Concrete Operational Stage
2nd – 6th Grade Decentering Taking into Account Multiple Aspects Of a Problem to Solve It Concrete Operational Stage
2nd – 6th Grade Seriation Arranging Objects in an order according To Size, Shape, Color or any other Attribute Such as Thickness Concrete Operational Stage
2nd – 6th Grade Classification When a child can name and identify sets of objects according to their appearance, size or other characteristic. Concrete Operational Stage
2nd – 6th Grade Reversibility Objects can be Changed and then Returned to their Original State Fact Families 4 + 5 = 9 9 – 5 = 4 Concrete Operational Stage
Formal Operational Stage (11+ years old) (Adolescence) In this stage, intelligence is demonstrated through the logical use of symbols related to abstract concepts. Early in the period there is a return to egocentric thought. Only 35% of high school graduates in industrialized countries obtain formal operations; many people do not think formally during adulthood. Cognitive Development
The teacher understands how children learn mathematical skills and uses this knowledge to plan, organize, and implement instruction and assess learning. C13-Mathematics Instruction
Numbers, Operations and Quantitative Reasoning Patterns, Relationships and Algebraic Thinking Measurement Geometry and Spatial Reasoning Probability and Statistics Underlying Processes and Mathematical Tools Six Strands of Mathematics
Instruction is organized in Units Heterogeneous Groups Manipulatives and Technology Communication Challenging Activities Ongoing Assessment Parent Involvement Ideal mathematics classroom
Prior Knowledge greatly influences the learning of math and that learning is cumulative and vertically structured. A student centered, discovery oriented approach which promotes conceptual knowledge and independent problem solving ability in students. Constructivist Approach
Set up learning situations Build mathematical understanding Provide opportunities for students to construct their own knowledge Provide experiences to stimulate their thinking Encourage discovery Use divergent questions Role of the Teacher
Concrete Stage Representational Stages Abstract Stage Stages of mathematical Development
Problem Solving Read the Problem Make a Plan Solve the Problem Reflect on the Answer Look for Reasonableness Central Teaching Strategy
Act It Out Draw A Picture Find a Pattern Make a Table or List Working Backward Use Smaller Numbers Problem Solving Strategies
Formative Summative Authentic Importance of Rubrics Mathematical Assessment
Teachers need to help students learn to value mathematics become confident in their own abilities become mathematical problem solvers learn to communicate mathematically learn to reason mathematically NCTM Standards

Place Value Difficulties • Using Zero when writing numbers • Regrouping • Addition/Subtraction • Identifying addition/subtraction situations • When numerals have a different number of digits • Multiplication/Division • Basic Facts • Distributive Property of multiplication over addition • Aligning partial products http://www.youtube.com/watch?v=e7Ult0p-uGU Common Mathematical Difficulties
Greatest Common Factor • Least Common Multiple • Exponents (Power of Ten) - 103 • Determining Events: There are four numbers (1,2,3 & 4) in a box. How many different ways can you select those numbers? • Combination: number of possible selections where the order of selection is not important : = 3 + 2 + 1 • 12, 13, 14, 23, 24, 34 • Permutation: number of possible selections where the order of selection IS important.: = (3 + 2 + 1) X 2 • = 12, 21, 13, 14, 41, 23, 32, 24, 42, 34, 43 Other Mathematical Difficulties
Combination: Order does not Matter • My fruit salad is a combination of apples, grapes and bananas • Permutation: Here the order does matter • The combination to the safe was 472. Combinations and Permutations
