Essential Questions: EU 1 mathematical notation and language is necessary for a strong foundation in Geometry. EU 1 What is the significance of proper notation in the study of geometry?. EU 2 geometric relationships and definitions can be used to construct geometric figures and solve real world problems. EU 2 Why do we measure? EU 3 good decision making requires logical reasoning based on known facts. EU 4 algebraic properties of equality are used in geometry to solve problems and justify reasoning. EU 2, EU 3 How does what we measure influence how we measure? EU 3, EU 4 Why is it important to think logically? EU 3, EU 4 What are the advantages and disadvantages to drawing conclusions from given information? LRHSD (2011) Adapted from ASCD © 2004 Lenape Regional High School District – BOE Approved 2/15/12 Knowledge: Students will know . . . EU 1, EU 2, EU 3, EU 4 special angle pairs can be used to identify geometric relationships and to find angle measures. EU 2 the special angle pairs formed by parallel lines and a transversal are either congruent or supplementary. formal geometric constructions can be created with a variety of tools and methods to provide a visual representation of geometric concepts. Skills: Students will be able to . . . EU 1 identify and model points, lines, planes and their relationships. identify and classify angles and their relationships. utilize correct mathematical language and notation to communicate ideas about geometric figures. EU 2 make formal geometric constructions using various methods. EU 3 make conjectures based on inductive reasoning. EU 3 determine necessary and sufficient conditions for a statement to be true. EU 2, EU 3 some mathematical relationships can be described using a variety of ifthen statements. EU 3 by comparing the slopes of two lines it can be determined whether the lines are parallel or perpendicular. EU 2, EU 3, EU 4 utilize angle relationships to solve problems. find the distance between a point and a line, and between two parallel lines. EU 3, EU 4 determine slopes of parallel and perpendicular lines. EU 3, EU 4 formulas can be used to find the midpoint and length of any segment in the coordinate plane. EU 3, EU 4 write the equation of a line. EU 3, EU 4 certain angle pairs can be used to determine whether two lines are parallel. EU 3, EU 4 formulate proofs involving segment and angle congruencies, parallel and perpendicular lines. EU 4 a line can be graphed and its equation written when certain facts about the line, such as its slope and a point on the line, are known. EU 3, EU 4 apply the midpoint formula and the distance formula to calculate length and midpoint. LRHSD (2011) Adapted from ASCD © 2004 Lenape Regional High School District – BOE Approved 2/15/12 Stage 2 – Assessment Evidence Recommended Performance Tasks:. You are seeking employment in the marketing field and will present your portfolio to a marketing director. Your portfolio will include a creative logo and slogan. The logo is comprised of segments only. The segments are to be constructed to form a variety of geometric figures that are related to your slogan and/or your product. The slogan, representing a product of your choosing that you will name, must be written as a conditional statement. Include an explanation of why you chose your product and how your logo is related to your product. All written work must be typed. Provide an oral/written/visual presentation of your finished product, including the geometric shapes contained in your logo. All other specifications and requirements are to be determined by the classroom teacher. Other Recommended Evidence: Tests and quizzes to include: naming and identifying points, lines, planes, and angles; finding distance and midpoints on a number line and in the coordinate plane; writing and solving algebraic equations about segment relationships and angle relationships; identifying the parts and different forms of conditional statements; proofs on algebraic equations, segment relationships, angle relationships, parallel lines and the angles formed by a transversal; writing linear equations; finding the distance between two parallel lines; constructions of/with segments, parallel lines, angles, bisectors, and perpendicular lines Assessed elements from the Performance Task Other teacher–graded evaluations LRHSD (2011) Adapted from ASCD © 2004 Lenape Regional High School District – BOE Approved 2/15/12 Stage 3 – Learning Plan Suggested Learning Activities: Before defining geometric figures, give examples and non-examples to have students discuss their observations. (A, M) Give students a diagram (such as the one below) and have them discuss what can or cannot be assumed.
