Assessment Items Unit Title: Structure and Language of Geometry Organizing Concept: 1. Congruence Transformation Questions to Assess Prior Knowledge: Distributive/Equality property 1.Why is -2(x -5) not equal to 2x – 10? 2. Draw the shape on a graph paper and a. Reflect across the x axis b. Rotate 180 degrees c. Translate up 5 units and to the right 2 untis Questions to Draw-out Misconceptions: 1. Describe what happens to a rectangle when you rotate it 90 degrees. 180 degrees, and 270 degrees clockwise about the origin. 2. Describe what happens to a trapezoid when you reflect it across it the y axis. Jeffco Public Schools May 2011 Assessment Items DOK 1: Determine if the given angle is acute, obtuse or a right angle. DOK 2: (given two parallel lines cut by a transversal with angle 2 measuring 47 degrees) What are the measures of the remaining 7 angles in the diagram? DOK 3: A B (if these two figures were super imposed on a coordinate grid) Specify the sequence of transformations that will carry figure A to figure B Jeffco Public Schools May 2011 Assessment Items DOK:4 Literacy – Writing to Learn: Organizing Concept: Proof and Construction Questions to Assess Prior Knowledge: How would you determine the following shapes are congruent: Line segment, angle. What does it mean to bisect a line segment, and a angle. How would you determine if two lines are perpendicular, and if two lines are parallel. Questions to Draw-out Misconceptions: DOK 1 Copy the line segment using tools of construction, make sure to show all marks. Jeffco Public Schools May 2011 Assessment Items DOK 2: Using patty paper verify that the two lines are parallel. DOK 3: Describe how you would accurately construct an angle of 135 degrees using only a compass and a straightedge. DOK:4 Organizing Concept: Proof Questions to Assess Prior Knowledge: 1. Show the steps of solving the equation to prove the answer is correct. IF 5(Y+4) = 20 THEN Y = 0 2. Identify the next three terms of the following sequence and explain your reasoning. 1, 3, 5, 7 Jeffco Public Schools May 2011 Assessment Items Questions to Draw-out Misconceptions: DOK 1: Is segment KM the angle bisector of angle JKL? DOK 2: Define inductive and deductive reasoning. DOK 3: Given the line and the point below, construct a new line parallel to the given line, your new line must contain the given point. Justify each step of the construction. DOK:4 Jeffco Public Schools May 2011 Assessment Items Literacy – Writing to Learn: Jeffco Public Schools May 2011
