Never Tell An Answer
Please remember the enormous
responsibility we all have as learners
not to spoil anybody else’s fun.
The quickest way to spoil someone else’s
fun is to tell them an answer before they
have a chance to discover it themselves.

Think-Pair-Share
Think:
What are the characteristics of a good problem
solver? In science? In math? Does it matter?
Pair – talk to a partner
Share with the group
Part 1: Standards for
Mathematical Practice
1.
Make sense of problems and persevere in
solving them
…start by explaining the meaning of a problem and looking for
entry points to its solution
2.
Reason abstractly and quantitatively
…make sense of quantities and their relationships to
problem situations
3.
Construct viable arguments and critique the
reasoning of others
…understand and use stated assumptions, definitions, and
previously established results in constructing arguments
4.
7
Model with mathematics
…can apply the mathematics they know to solve problems arising in
everyday life, society, and the workplace
Part 2: Standards for
Mathematical Practice
5.
Use appropriate tools strategically
…consider the available tools when solving a
mathematical problem
6.
Attend to precision
…communicate precisely using clear definitions and
calculate accurately and efficiently
7.
Look for and make use of structure
…look closely to discern a pattern or structure
8.
Look for and express regularity in
repeated reasoning
…notice if calculations are repeated, and look for both
general methods and for shortcuts

Hooked on Algebra

Models for Understanding Linear Functions
Elasticity is the ability of a material to spring back to
its original shape and size after it has been stretched
 Robert Hooke called the force acting upon a material
the stress, and the elongation it produces the
strain
 Complete the experiment, graph your data, and write
about what you notice
 Based on your work, what is the relationship between
the stress and the strain?

What Are We Doing?

Where in the world does Hooked on Algebra fit?
Is it math?
 Is it science?
 Are math practices addressed?
 Are science and engineering practices addressed?
