Problem Solving and Supporting Algebraic Thinking at the Middle and Secondary Grades Amy Barto LDA of Michigan November 14, 2011
Food For Thought • “Mathematical know-how is not only one of the most important qualities for workers to possess in the future, it is critical for successful functioning in life”. - Jo Boaler, 2008.
More Food For Thought “… twenty-first-century citizens need mathematics. But the mathematics that people need is not the sort of math learned in most classrooms. People do not need to regurgitate hundreds of standard methods. They need to reason and problem solve, flexibly applying new methods in new situations. Mathematics is now so critical to American citizens that some have labeled it the ‘new civil right’.” - Jo Boaler, 2008.
Functions • Graphs • Probability • Statistics Patterns Number Sense Place Value Operations Formulas
DO THIS AT HOME! • Concept A: Mathematical Representations Around Us • 5 minute Math Hunt: Examples of Math Around Us • Output: Make a List & Be Able to Defend Mathematical Connection (can be related to most recent unit of instruction) • Concept B: Number Sense • 5 minute Number Hunt: Representations of • Levels of Difficulty = Differentiation • Whole Numbers; decimals; fractions, exponential numbers • Output: Make a List (must have different types of examples; i.e. not a list of numerals)
Speaking of…… • “Children need to solve complex problems, to ask many forms of questions, and to use, adapt, and apply standard methods, as well as to make connections between methods and to reason mathematically – and they can engage in such methods at home and (one hopes) at school”. - Jo Boaler, 2008.
7th and 8th Grade Students
Sarah’s father is 60 years old. Sarah is ¼ as old her father. How many years older than Sarah is her father? At what age will Sarah be 1/10 her father’s age?
Good Problem Solvers Solve Problems Based on Common Structures
READ • READ the problem. Decoding the Text Decoding the Math
Identify the important information. More than key words. Mathematical Concepts Put it into (your own) words. LANGUAGE gives meaning.
Diagram Graph Chart A Schematic: A MAP or math blueprint MUST RELATE TO THE PARAPHRASE.
Make a plan Choose operations Putting together the puzzle…. Setting up your mathematical experiment/notation Pattern and Logic in Mathematical Language
Create a realistic target. The Goal is the 2nd Ring – not a bullseye. Relies on Comprehension of Mathematical Concept/Operations.
Computation Supports Multiplication Chart Calculator Tactile Materials Visualization & Hypothesis Self-Made Supports Self-talk & routine Developing Algorithms
Using the Inverse “Am I right?” “I am right AND I can prove it.” Meta-cognition.
Back to The Fun Stuff!!!!! Sarah’s father is 60 years old. Sarah is ¼ as old her father. How many years older than Sarah is her father? At what age will Sarah be 1/10 her father’s age?
The ultimate goal of mathematics education is for all students to develop mathematical power to participate fully as a citizen and worker in our contemporary world.
