The
learner will: Understand and apply concepts and procedures from number sense BENCHMARKS
Number and Numeration Understand and use properties and symbolic representations of rational numbers Explain the magnitude of numbers by comparing and ordering rational numbers Understand concepts of and use processes involving prime and composite numbers, factors and multiples, and divisibility Computation
Understand operations on rational numbers Compute with rational numbers, powers, and roots Use mental arithmetic, pencil and paper, calculator, or computer as appropriate to the task involving real numbers Estimation
Identify situations involving whole numbers in which estimation is useful Use estimation to predict computation results and to determine the reasonableness of answers, for example, estimating a grocery bill |
To meet this standard the
learner will: 1.1 Write ratios in simplest forms (6-1) Evaluate powers of variables Use exponents to express repeated multiplication. Evaluate powers of variables Use the distributive property to simplify calculations. Decide whether estimates are reasonable or likely. Review operations with negative numbers. Read and write numbers in scientific notation. Estimate lengths and areas. Find square roots and cube roots Distinguish rational numbers from irrational numbers. 1.1.4 Simplify and multiply square roots (9-2) 1.1.5 Use inequalities to describe number line graphs Use the formula for the area of a circle (7-6) Use shortcuts for simplifying powers |

The
learner will: Understand and apply concepts and procedures from measurement BENCHMARKS
Attributes
and dimensions
Understand how changes in dimension affect perimeter, area, and volume Measure objects and events directly or use indirect methods such as finding the volume of a cone given its height and diameter Calculate rate and other derived and indirect measurements Approximation
and precision
Understand that measurement is approximate Estimate to predict and determine when measurements are reasonable, for example, estimating how much paint is needed to paint the walls of a classroom Systems
and tools
Understand the benefits of standard units of measurement and the advantages of metric systems Select and use tools that will provide an appropriate degree of precision, for example, using kilometers vs. light years |
To
meet this standard the learner will: 1.2.1 Find the area of a circle and sectors of circle (7-6) 1.2.2 Find the surface areas of prisms, cylinders, ad pyramids (9-5) Find the volumes of prisms, cylinders, pyramids and cones (9-6, 9-7) 1.2.3 Use dimensional analysis to work with nits in rates and conversion
factors (7-5) Recognize how rate and initial value of a real-life situation appear in
an equation and a graph representing the situation. Estimate lengths and areas Build quadrilaterals from congruent triangles and write expressions for
triangles and write expressions for their perimeters. Find the areas of polygons drawn on a coordinate plane (4-2) |
