# #07 Math Lab (grades 7-12)

Regular price \$20.95

Soft-bound, 56 page book, 20 reproducible task cards, full teaching notes.
Great hands-on math: assemble sequences with pennies, create art based on the Fibonacci sequence, fold clever curves, travel a Mobius strip. Go on to crack bar codes, solve puzzles, experience a generalization that turns out to be false. From limits to logarithms, build both math curiosity and math confidence.

• Lesson 1: To discover patterns in the arrangement of pennies that form number sequences.
• Lesson 2: To discover patterns in the arrangement of squares that form number sequences. To write a general term for each sequence.
• Lesson 3: To discover patterns in the Fibonacci sequence, and apply it to a study of population.
• Lesson 4: To draw Fibonacci squares and construct the spiral of a chambered nautilus.
• Lesson 5: To study the golden mean as a ratio of Fibonacci numbers. To create a work of art based on this proportion.
• Lesson 6: To generate a sequence of regions by joining points on the circumference of a circle. To recognize the tentative nature of predictions based on generalizations.
• Lesson 7: To trace the path of a ball as it is deflected across a hypothetical pool table. To recognize the tentative nature of predictions based on generalizations.
• Lesson 8: To approximate a curve with straight lines. To recognize that n-sided polygons approach the shape of a perfect circle as n increases.
• Lesson 9: To define a circle and draw it with a smooth curve. To approximate another circle with many straight fold lines.
• Lesson 10: To define and construct an ellipse. To form a curved figure from straight fold lines and evaluate its shape.
• Lesson 11: To construct a parabola using many straight fold lines. To develop a definition based on its properties.
• Lesson 12: To define a cardioid and draw it using circles of Styrofoam. To approximate another cardioid with straight lines.
• Lesson 13: To cut and tape the interior angles of polygons, and find their sums. To understand how this sum increases as the number of sides of the polygon increases.
• Lesson 14: To discover number patterns that simplify the addition of long sequences of numbers.
• Lesson 15: To list all prime integers under 100 and examine their properties.
• Lesson 16: To develop a table of logarithms that simplify mathematical computations. To practice four basic log operations.
• Lesson 17: To discover number patterns in a slide and jump game. To generalize an nth term for each pattern.
• Lesson 18: To be surprised by the unusual topological properties of a Mobius strip.
• Lesson 19: To interpret bar codes used by the U.S. postal service that automate mail sorting.
• Lesson 20: To cut out 12 unique 5-tile puzzle pieces and use them to construct rectangles of various dimensions.
We encourage improvisation - it's one of the main goals of our hands-on approach! You and your students might invent a simpler, sturdier or more accurate system; might ask a better question; might design a better extension. Hooray for ingenuity! When this occurs, we'd love to hear about it and share it with other educators.
National Science Education Standards (NRC 1996)

#### TEACHING Standards

These 20 task cards promote excellence in science teaching by these NSES criteria:
Teachers of science...
A: ...plan an inquiry-based science program. (p. 30)
B: ...guide and facilitate learning. (p. 32)
C: ...engage in ongoing assessment of their teaching and of student learning. (p. 37)
D: ...design and manage learning environments that provide students with the time, space, and resources needed for learning science. (p. 43)

#### CONTENT Standards

These 20 task cards contain fundamental content as defined by these NSES guidelines (p. 109).
• Represent a central event or phenomenon in the natural world.
• Represent a central scientific idea and organizing principle.
• Have rich explanatory power.
• Guide fruitful investigations.
• Apply to situations and contexts common to everyday experiences.
• Can be linked to meaningful learning experiences.
• Are developmentally appropriate for students at the grade level specified.

#### Unifying Concepts and Processes

NSES Framework: Systems, order, and organization • Evidence, models and explanation • Constancy, change, and measurement • Evolution and equilibrium • Form and function
Core Concepts/Processes: Induction says that what is true for the particulars is true in general. Such claims, while reasonable, are never absolutely certain.

#### Science as Inquiry (content standard A)

NSES Framework: Identify questions that can be answered through scientific investigations. • Design and conduct a scientific investigation. • Use appropriate tools and techniques to gather, analyze, and interpret data. • Develop descriptions, explanations, predictions, and models using evidence. • Think critically and logically to connect evidence and explanations. • Recognize and analyze alternative explanations and predictions. • Communicate scientific procedures and explanations. • Use mathematics in all aspects of scientific inquiry.
Core Inquiries: Recognize patterns • Think inductively • Generate nth terms • Ellipses • Parabolas • Cardioids • Prime numbers • Logarithms • Solve puzzles

#### History and Nature of Science (content standard G)

NSES Framework: k458912 Science as a human endeavor • Nature of science • History of science
Core Content: Explore patterns and shapes of historical significance - the Fibonnacci series, Mobius strips, ellipses, parabolas, and the golden mean.
