Title: Variables & Equations
Learning Target: You will learn to classify different types of equations.
Vocabulary
Equation- a mathematical sentence with an equals sign (Example 9+2=11 or X+8=11).
Open Sentence-an equation with one or more variables (Example 6x+2=8 or 6x+y=8).
Solution-a value for a variable that makes a number sentence true (Example x+5=10, where x=5 is the solution.
9/22/08 simplify variable expressions
HOMEWORK: p.77 #11-16 & 19-30
Learning target:you will learn how to model variable expressions and simplify them.
Vocabulary:
- term-a number OR product of the number and its variables…
- constant-a term that has no variable.
- like terms-have identical variables.
- coefficient-a number that multiplies a variable/
- simplify-to take a large expression,combine like terms and make it asa small as possible.
9/22-9/26 Geometry
There will be no Geometry homework this week as Challenge class is in Canyonlands. For those couple of students remaining behind, there will be projects to do in class, but no homework. Mrs. Bichler

9/17/08 Pre-Algebra Homework and Notes
HOMEWORK: p.83 #20-23
NOTES:
Distributive Property- combines multiplication with addition and subtraction. This property is often used in mental math to help you find the answer to a multiplication question faster.
Example:
29(3)
To use the distributive property, write 29 in expanded form: 20 + 9
Then, multiply 3 by the 20 and the 9
3(20 + 9)
Then, add the sums of your multiplication:
3(20)= 60 and 3(9)=27
60 +27 = 87
9/17/08 Geometry Homework and Notes
HOMEWORK: Study conditional statements and their inverse, converse, and contrapositive. Also, study and be able to identify biconditional statements, their converse, and determine if they are true biconditional statements. You may have 1/2 page of notes to help you with your quiz tomorrow. p. 83 #20-23 is also your homework.
Lesson 2.2 Definitions & Biconditional Statements
You will continue your learning and exploration o f conditional statements by identifying biconditional statements and their converse.
Vocabulary:
Definitions- in geometry a definition can be read and interpreted forward and backward.
Biconditional statements: uses the phrase “if, and only if” and is made up of a conditional statement and its converse.
Examples:
Definitions:
If two lines intersect to form a right angle, then they are perpendicular.
Read backwards: If two lines are perpendicular, then they intersect to form a right angle.
Biconditional Statement:
It is Saturday, only if I can sleep in.
It’s conditional statement is: If it is Saturday, then I can sleep in.
It’s converse is: If I can sleep in, then it is Saturday.
This is not a true biconditional statement because the biconditional statement and its converse must both be true.
For example, in the summer time we sometimes sleep in on days other than Saturday…whoo hoo!
