Adding It Up: Helping Children Learn Mathematics
The research evidence is consistent and compelling showing the following weaknesses: US students have limited basic understanding of mathematical concepts They are notably deficient in their ability to solve even simple problems And, overall, are not given educational opportunity they need to achieve at high levels In short, the authors tell us that US teachers focus primarily on one area, computation.

Strategic Competence Conceptual Understanding Procedural Fluency Adaptive Reasoning Productive Disposition
Let’s give kids something they can hold on to!
Conceptual Understanding “When knowledge is learned with understanding it provides a basis for generating new knowledge.” It is comprehension of concepts, operations and relationships It helps students avoid critical errors in problem solving It is being able to represent mathematical situations in different ways
What do these say about the student’s Conceptual Understanding?
1/3 + 2/5 = 3/8 16 - 8 12 9.83 x 7.65 = 7,519.95
Discussion Questions
What is Conceptual Understanding?
How do we teach for Conceptual Understanding?
What does it look like when students have Conceptual Understanding?
Procedural Fluency Skill in carrying out mathematical steps and computations Understanding concepts makes learning skills easier, less susceptible to common errors, and less prone to forgetting Using procedures can help to strengthen and develop understanding
Does Practice Make Perfect?
Understanding concepts helps recall procedures correctly Mastering concepts fosters the ability to choose appropriate math tools and strategies
How Do You Know They Got It?
What are some successful strategies you use to develop procedural fluency?
How are procedural fluency and conceptual understanding related?
How would you solve this problem?
A cycle shop has a total of 36 bicycles and tricycles in stock. Collectively there are 80 wheels. How many bicycles and how many tricycles are there?* *Adding It Up, National Research Council, 2001, p.126
Questions to Consider
What is the problem?
What do you need to know to solve this problem?
Describe more than one way to solve this problem?
Strategic Competence The ability to formulate, represent and solve mathematical problems.
Formulate problems Multiple strategies Flexibility Nonroutine problems vs. routine problems
Allow nonroutine problems to be the vehicle to build Strategic Competence.
Adaptive Reasoning “…the glue that holds everything together.” Adaptive Reasoning is the capacity for: Logical thought Reflection Explanation Justification
Conditions Needed
Real-world, motivating tasks Utilizes the knowledge-base and experience that children bring to school Rigorous questioning Students justify their work on a regular basis
Questions
How do you promote adaptive reasoning in your classroom?
What is the evidence that your students are regularly using adaptive reasoning?
What are the long-term benefits of students utilizing adaptive reasoning?
Productive Disposition Mathematics makes sense Mathematics is useful and worthwhile Steady effort Effective learners and doers
Key Points
Emotional development Self-efficacy and self-image Stereotype threat Peer pressure to under-achieve “Wise educational environments” Affective filter - math as a “second” language
Application
How do teachers’ feelings/perceptions toward math affect productive disposition?
How can SDAIE teaching strategies increase productive disposition in math?
Mathematical Proficiency
Conceptual Understanding Strategic Competence
Ability to solve mathematical problems Comprehension of mathematical concepts
Procedural Fluency
Knowledge of algorithms
Adaptive Reasoning
Capacity for logical thought, reflection, explanation and justification
Productive Disposition
Views mathematics as sensible, useful, & worthwhile, coupled with a belief of ability
Bringing It All Together
How do the five strands of mathematical proficiency relate to standards-based instruction?
How will you incorporate mathematical proficiency into daily teaching practice?
In Conclusion
The goal of instruction should be mathematical proficiency It takes time for mathematical proficiency to be fully developed Mathematical proficiency spans number sense, algebra & functions, measurement & geometry, SDAP, and mathematical reasoning
“All young Americans must learn to think mathematically and must think mathematically to learn.”
