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 real 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: 1.1.6 Use negative, zero, and fractional exponents (2-6) 1.1.2 Find the number of ways to select some items from a group (6-5) Use the multi-counting principle to find a number of possible arrangements of items (6-2) 1.1.4 Use quadratic formula to solve quadratic equation.	1	2	3	4	5

Suggested Instructional Strategies / Activities

Resources & Materials

2-6 Do pg. 99 “Exploration” Integrated II text. Uses a graphing calculator to explore how a calculator treats fractional and negative exponents. Students use graphics calculators to explore negative and zero exponents and come up with definition. 6-5 Do pg. 328 “Talk it over” As partner activity. 6-2 Do pg. 302 “Exploration” Uses letters on note cards to manipulate them into all possible arrangements. Negative, Zero, and Fractional exponents. Q: 2^2(2^3)=? A:2^5(a^x.a^y=a^x+y) Q: 2^5/2^3=? A:2^2(a^x/a^y=a^x-y) 1=2^3/2^3=2^3-3=2^0 Similar argument for negative and fractional exponents. Reinforce by using calculator.

TI-82 Calculator & Int. II text Int. II text and TI-82 Calculator Int. II text 4 index cards & a partner. Whiteboard, paper, pencil, calculator.

GOAL: The student understands and procedures of mathematics.

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: 1.2.2 Find the surface area and volume of spheres (2-6,2-4) Find the distance between two points in three dimensions (10-5)	1	2	3	4	5
