OBJECTIVE: Evaluate numerical and simple algebraic expressions(1-8, Pp28ff) ACTIVITIES: a) Monroe-Sherman Evalution b)Introduce concepts and terminolgy including EXPRESSION EQUATION EVALUATE VARIABLE CONSTANT OPERATION. c)indicate methods of writing operations (fraction bar, etc.) d) intreoduce math facts drills on the computers. NOTES: Assembly Schedule - Magazine Sale HOMEWORK: Define VARIABLE CONSTANT EXPRESSION OPERATION by writing a sentence which demonstrates meaning - NOT a defintion!!!! For example - using the term EVALUATE: When you EVALUATE 2+3 you find the value of 5.

Problem of the week (check the scoring guide) The problem of the week is due on Friday. Students are to use diagrams, charts, and tables as needed. Explain the process used to solve the problem. Be neat. Last Week's solution...
Rounding Mountains
Mount Everest is roughly thirty thousand feet high. Actually that is the height rounded to the nearest ten thousand feet. Mount Cook measures in at roughly ten thousand feet. Again this is the height rounded to the nearest ten thousand feet.
Given these estimates, find the difference between the greatest possible height and the least possible height of the two mountains.
Explain in mathematical terms why this difference is larger than the difference of twenty thousand between the two estimated figures.
Bonus: Name the tallest mountain on the continent where you live and give the height of that mountain? Be sure to tell me where you found the information.
