MYP 4 Ms. Lesley Ballew Room 405 [email protected] (808) 261-0707 x2160 Mathematics 9 Mr. Joshua Lyons Room 404 [email protected] (808) 261-0707 x2310 MYP 4 Integrated Math will focus primarily on topics from both Algebra and Geometry. The course will stress the essential role of mathematics within the school and in society: mathematics as a universal language, promoting analytical reasoning and problem-solving skills that contribute to the development of logical, abstract, and critical thinking. This course will help students view mathematics as a language of modeling and solving problems that arise in the real world. 2014 – 2015 Scope and Sequence: August-December All Unit Dates are projected and may be subject to change. You will be sent a January-May Scope and Sequence in January. Unit 1: Triangles in Design Late Aug- Mid Oct Key concept: Logic Related concepts(s): Justification, Generation Global context: Scientific and Technical Innovation: Engineering Inquiry statement: To justify engineering decisions we can use logical reasoning to arrive at general conclusions. Inquiry questions: Factual: What justification is needed in order to prove two triangles are congruent? What are the relationships between the angle measures and the side lengths of a triangle? What relationship must three line segments have with each other to form a triangle? Conceptual: Why does a rectangular gate become more stable when a diagonal is added on to it? Why is a general theorem a more valid justification than a statement specific to a problem? Debatable: Is there one best way to construct a proof or convincing argument?

Inquiry questions: Factual: What are the relationships between the side lengths of a right triangle? What makes two figures similar? How can we measure the distance between two points on a coordinate plane? Conceptual: Why does SOH-CAH-TOA only work on right triangles? How does the sun allow us to measure the height of an object? Debatable: Can solar energy be a sustainable replacement of fuel energy in Hawaii? Content • Know: Properties of similar figures, Pythagorean Theorem, distance formula, Special Right triangles, Right Triangle Trigonometry. • Understand: All right triangles have the same relationship between the side lengths, angle of elevation and depression, and trigonometric ratios. • Do: Calculate missing measures of a right triangle given different combinations of information and to construct a solar oven assessed with right triangle trigonometry.
