Research Assignment for all students: Due on 3-20, 2006

Communication 2.2.2: Applies skills and strategies to contribute responsibly in a group setting.

Research using an almanac, a geography text, or the Internet to find the following 3 items:

  1. select a unique location in your assigned time zone.
  2. find the average temperature.
  3. average rainfall.

Place your data on a 3x5 card and connect it with a piece of yarn to the appropriate map location for your class.

Possible Information Source

In addition to Communications 2.2.2 this assignment is based on the following math outcomes: 3.1.1 Analyze information from a variety of sources to interpret and compare information   and   4.2.2 Apply communication skills to clearly and effectively express or present ideas and situations using mathematical language or notation.

OBJECTIVE: 1.5.6 Understand and apply a variety of strategies to solve two-step equations with one variable. * Explain and justify the solution to a problem in a given context. [RL, CU, MC] * Solve two-step equations with one variable on only one side of the equal sign (e.g., 2x + 4 = 12). 1.5.5 Understand and apply procedures to evaluate expressions and formulas considering order of operations. * Substitute non-negative rational values for variables in order to evaluate expressions and formulas (e.g., length x width when length=3 and width=4) * Explain the simplification of expressions and equations using order of operations. [CU] * Evaluate expressions and formulas considering order of operations. [RL] * Determine the expression that represents a given situation. [MC, CU] * Describe a situation that fits with a given expression. [RL, MC, CU] * Write expressions or equations for a situation. ACTIVITIES/ASSESSMENT: Test on 1-step equations; review of expressions and simplifying and/or combining expressions (include order of operation) and an introduction to 2-step equations. NOTES: HOMEWORK: 5 2-step equations
