GRADE 8

GOAL: The student understands and applies the concepts and procedures of mathematics.

Washington State Essential Academic Learning Requirements	Meridian School District Math Framework	Assessment Strategies
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 Understand and apply the concepts of ratio and both direct and indirect proportion. 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 Find patterns to discover greatest and least sums of two digit numbers from four unique digits Define concepts of opposite operations and distributive property Use factor tree to demonstrate prime factorization Use number line to compare rational and irrational numbers Use power of ten notation and simplification of square roots to combine like terms Use rule of rounding to mentally calculate estimates Write and solve real life problems using whole numbers Estimate distances and apply to equations to solve using rules of distributive and associative properties.	1	2	3	4	5

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 Use metric and English units of measure to find greatest area given fixed perimeter Use formulas to calculate areas and volumes of geometric objects from investigative measurements. Experiment with ball and cart to derive distance formulas, rate and units of velocity Deem appropriate units- comparing metric and English units of measure using ruler, meter stick, yard stick, fifteen meter tape and micrometer Measure items in meters, centimeters and millimeters- comparing results and estimation of measurements before activity	1	2	3	4	5<
