Nine Weeks Focus
Skills/Standards	Number, Number Sense, and Operations Standards K 1 2 3 4 5 6 7 8 9 10 11 12 Measurement Standard 1. Explain how a small error in measurement may lead to a large error in calculated results. 2. Calculate relative error. 3. Explain the difference between absolute error and relative error in measurement. 4. Give examples of how the same absolute error can be problematic in one situation but not in another; e.g., compare “accurate to the nearest foot” when measuring the height of a person versus when measuring the height of a mountain. Geometry and Spatial Sense Standard 2. Recognize and explain the necessity for certain terms to remain undefined, such as point, line and plane. 3. Make, test and establish the validity of conjectures about geometric properties and relationships using counterexample, inductive and deductive reasoning, and paragraph or two-column proof, including: c. prove theorems involving properties of lines, angles, triangles and quadrilaterals; d. test a conjecture using basic constructions made with a compass and straightedge or technology. 8. Derive coordinate rules for translations, reflections and rotations of geometric figures in the coordinate plane. Patterns, Functions, and Algebra Standard6 7 8 9 11 12 4. Use algebraic representations and functions to describe and generalize geometric properties and relationships. 9. Recognize and explain that the slopes of parallel lines are equal and the slopes of perpendicular lines are negative reciprocals. Data Analysis and Probability Standard
