8/22/06 Algebra 1

Today in class we introduced/reviewed the idea of a variable, what it stands for and how to evaluate an expression involving a variable. Our objectives are to evaluate a variable expression, use unit analysis to provide correct units for our answer, and take a verbal model and translate it to an expression using numbers and variables that we can then evaluate. Students practiced these in class with a worksheet and we will test them with our 1.1 Lesson test on Thursday.
Homework due for Thursday:
Pages 6-8 #'s 20-30 even, 36 & 38. #48 can be done for extra credit.

Examples:
1)Evaluate 8x if x=7.
2)Give the amount and units for traveling 70 miles per hour for 4 hours.
3)A baseball player's batting average can be found by taking the number of hits divided by at-bats. Find the batting average for a player with 50 hits in 200 at-bats.

Today our objectives were to familiarize the students with the real numbers and their subsets (Whole Numbers, Integers, Rational & Irrational Numbers). Students also will be responsible for ordering these different types of numbers, according to their value on the number line. Third, we will review the properties of real numbers and how they apply to algebra. Students will also review simple arithmetic operations and convert units (such as feet per second to miles per hour). We will open class on Thursday with the 1.1 lesson test.
Homework for Thursday:
Pages 7-9, #'s 28-42 even, 54 & 60.
