MED 6312Content Instruction in the
Elementary School: Mathematics
Session 1
Reflective Questions
• What does it mean to do mathematics?
• What kind of language do you use when doing math?
• What kind of classroom environment needs to be developed?
What is Mathematics?
Mathematics is a study of patterns and relationships.
Mathematics is a way of thinking.
Mathematics is an art, characterized by order and internal consistency.
Mathematics is a language that uses carefully defined terms and symbols.
Mathematics is a tool.
The changing landscape of elementary mathematics teaching and learning
• A distinction between conceptual knowledge and procedural knowledgeMathematical procedures (algorithms)
enable you to find answers to problems according to set rules
Conceptual understanding enables you to find answers to problems in a variety of ways because you understand the underlying concepts of the problem.
The changing landscape of elementary mathematics teaching and learning
• Problem-focused teaching Instead of teaching mathematics as if it were
some naked, abstract, symbol manipulation, we are teaching mathematics as it occurs in our lives.
• Ask students to solve problems in a way that makes sense to them
• Then build new knowledge on their previous understandings
The changing landscape of elementary mathematics teaching and learning
• Communication in a mathematics classroomStudents learn best in a communityExpressive and receptive communicationMake and test mathematical conjectures
• Conjecture: an idea proposed as a possible explanation or generalization that seems to be true but which should be tested further.

• Mathematical connectionsUnderstanding how things are
connected and related to each other

• Connecting mathematics and other school subjects
• Connecting mathematics and real life
What determines the math we teach?• National Curriculum Standards
National Council of Teachers of Mathematics (NCTM)
• New Common Core
• State Core Curriculum
• District Standards
• Federal and State MandatesNAEPTIMSS
NCTM Principles of MathematicsParticular features of high-quality mathematics education
• Equity – Excellence in mathematics education requires equity—high expectations and
strong support for all students.• Curriculum
– A curriculum is more than a collection of activities: it must be coherent, focused on important mathematics, and well articulated across the grades.
• Teaching – Effective mathematics teaching requires understanding what students know and
need to learn and then challenging and supporting them to learn it well.• Learning
– Students must learn mathematics with understanding, actively building new knowledge from experience and prior knowledge.
• Assessment – Assessment should support the learning of important mathematics and furnish
useful information to both teachers and students.• Technology
– Technology is essential in teaching and learning mathematics; it influences the mathematics that is taught and enhances students' learning.

PROCESSES
• Problem Solving
• Reasoning and Proof
• Communications
• Connections
• Representation
Problem Solving
• Instructional programs from prekindergarten through grade 12 should enable all students to—
• build new mathematical knowledge through problem solving;
• solve problems that arise in mathematics and in other contexts;
• apply and adapt a variety of appropriate strategies to solve problems;
• monitor and reflect on the process of mathematical problem solving.
Problem Solving
• What does a problem solving-based classroom . . . Look like? Sound like? Act like?
• What is the difference between exercises and problems?
What kinds of things do you need to consider as a teacher as you orchestrate problem solving activities?
• Build a positive classroom atmosphere where students feel secure to express their developing ideas.– Knowledge - give experiences that are successfully reachable.– Beliefs and affect – success, everyone can do it– Control – students learn to monitor their own thinking
• Time – give time to think
• Planning – coordinate when students can do practice exercises, write in journals, try challenging problems.
• Resources – have many additional resources available including real life materials
• Use Technology
• Classroom management – train them from the beginning of the year to work in groups
• Pose problems effectively
Problem Solving Strategies
• Act it out
• Draw a picture
• Use simpler numbers
• Look for a pattern
• Make a table
• Make an organized list
• Look at all the possibilities
• Guess, check, and improve
• Work backward
• Write an equation
Reasoning and Proof
• Instructional programs from prekindergarten through grade 12 should enable all students to—
• recognize reasoning and proof as fundamental aspects of mathematics;
• make and investigate mathematical conjectures;
• develop and evaluate mathematical arguments and proofs;
• select and use various types of reasoning and methods of proof.
Reasoning and Proof
• What is reasoning? Is it separate, the same, or overlapping problem
solving? What reason, what proof do you have that
something is true?
• Reasoning builds thinking through making connections and generalizations
• Example: What is the definition of “quarter?”
Communication
• Instructional programs from prekindergarten through grade 12 should enable all students to—
• organize and consolidate their mathematical thinking through communication;
• communicate their mathematical thinking coherently and clearly to peers, teachers, and others;
• analyze and evaluate the mathematical thinking and strategies of others;
• use the language of mathematics to express mathematical ideas precisely.
Communication
• How can we communicate mathematically? Writing Conversation Prepared presentations Graphs Pictures Symbolic representations
• Communication helps students identify, clarify, organize, articulate, and extend thinking.
• Writing helps review, reiterate, consolidate thinking.
Connections
• Instructional programs from prekindergarten through grade 12 should enable all students to—
• recognize and use connections among mathematical ideas;
• understand how mathematical ideas interconnect and build on one another to produce a coherent whole;
• recognize and apply mathematics in contexts outside of mathematics.
Connections
• Connections within mathematical ideas Example: what does division mean?
• what it means for whole numbers, decimals, fractions, integers, etc.
• Connections between math symbols and concepts How can the area of a circle be measure in square
units?
• Connections between math and the real world Make a scale model of the classroom and arrange
desks.
Representation
• Instructional programs from prekindergarten through grade 12 should enable all students to—
• create and use representations to organize, record, and communicate mathematical ideas;
• select, apply, and translate among mathematical representations to solve problems;
• use representations to model and interpret physical, social, and mathematical phenomena.
Representation
• Different representations for an idea can lead us to different ways of understanding and using that idea.
What does it mean to learn mathematics?
Sociocultural Theory - Vygotsky
• Mental processes exist between and among people in social settings
• From social settings, the learner moves ideas into his or her own psychological realm
• Information is internalized is it is within the learner's ZPD
• Semiotic mediation -- the way information is internalized -- through social interaction and interaction with diagrams, pictures, and actions
Implications
• Build new knowledge on prior knowledge
• Provide opportunities to talk about mathematics
• Build in opportunities for reflective thought
• Encourage multiple approaches
• Treat errors as opportunities for learning
• Scaffold new content
• Honor diversity
A note about manipulatives . . . .
Use them to help students understand and explore mathematical concepts and relationships, to see patterns. Don't prescribe their use or fail to help students connect the dots.
Becoming a Teacher of Mathematics
1. A profound, flexible, and adaptive knowledge of mathematics.
2. Persistence
3. Positive attitude
4. Readiness for change
5. Reflective disposition
