1. 1. Tech Math 2 Day 1 Review
2. 2. Tech Math 2 Mr. Kiser W arm up <ul><li>What is the next letter in the following series? O T T F F S S E </li></ul><ul><li>The letters in the alphabet fit into 3 different levels. I’ve given you some of them, you give me the rest </li></ul><ul><li>Level 1: A, E, F, H, I ,K, L, M, N </li></ul><ul><li>Level 2: B, D, G, J, P </li></ul><ul><li>Level 3: C, O </li></ul><ul><li>You have 1 second left. </li></ul>
3. 3. What is the next letter in the following series? O T T F F S S E <ul><li>N </li></ul><ul><li>Each letter is the first letter of the integers when spelled out (One, Two, Three, Four, Five, Six, Seven, Eight… N ine) </li></ul>
4. 4. “Letter Levels” <ul><li>Level 1: A E F H I K L M N T V W X Y Z </li></ul><ul><li>Level 2: B D G J P (Q) R (U) </li></ul><ul><li>Level 3: C O (Q) S (U) </li></ul><ul><li>Level 1: Letters contain only straight lines </li></ul><ul><li>Level 2: Letters contain straight line and curves </li></ul><ul><li>Level 3: Letters contain only curves </li></ul>
5. 5. Course Description and Expectations <ul><li>Classroom Guidelines </li></ul><ul><li>ALL SCHOOL RULES APPLY. </li></ul><ul><li>In addition: </li></ul><ul><li>1. Be seated and working on the warm-up by the tardy bell. </li></ul><ul><li>2. Participation is required at all times. </li></ul><ul><li>3. Stay seated and quiet.

No food or drinks allowed. </li></ul><ul><li>Syllabus </li></ul>
6. 6. Tech Math 2 Wiki <ul><li>What is a wiki????? </li></ul><ul><li>A wiki is a web site that lets any visitor become a participant:  you can create or edit the actual site contents without any special technical knowledge or tools. All you need is a computer with an Internet connection. A wiki is continuously “under revision.” It is a living collaboration whose purpose is the sharing of the creative process and product by many. One famous example is Wiki-pedia, an online encyclopedia with no “authors” but millions of contributors and editors. The word &quot;wiki&quot; comes from Hawaiian language, meaning &quot;quick&quot; or &quot;fast.&quot; </li></ul>
7. 7. byhstechmath2.pbworks.com <ul><li>Ongoing student created “final exam study guide” </li></ul><ul><li>Vocab, examples, tricks/hints </li></ul><ul><li>Difficult/multi-step problems for you to collaborate on and solve </li></ul>
8. 8. Review Real Numbers <ul><li>Natural/Counting Numbers – Numbers you count with </li></ul><ul><li>Whole Numbers – 0 and all counting numbers </li></ul><ul><li>Integers – Positve and negative whole numbers </li></ul><ul><li>Rational Numbers – all numbers that can be represented as a fraction </li></ul><ul><li>Irrational Numbers – Numbers that cannot be represented by a fraction </li></ul>
9. 9. Classifying Real Numbers Give an example number for each situation and the group that the number belongs to. <ul><li>The amount of gas in your car’s gas tank in gallons after a trip to Walmart </li></ul><ul><li>The number of flies in a bowl of fruit at a picnic </li></ul><ul><li>The balance of an overdrawn bank account at Wachovia </li></ul><ul><li>The number of students in this class today </li></ul><ul><li>The number of pizzas eaten at a party </li></ul><ul><li>Your shoe size </li></ul><ul><li>The number of people living in your house </li></ul><ul><li>Your exact age right now </li></ul><ul><li>The number of days in a leap year </li></ul>
10. 10. Comparing Real Numbers <ul><li>Number lines will help </li></ul><ul><li>Numbers are arranged in order from least to greatest with negative numbers on the left and positive numbers on the right </li></ul>
11. 11. Symbols for Comparing Numbers <ul><li>A < B A is less than B </li></ul><ul><li>A > B A is greater than B </li></ul><ul><li>A ≥ B A is greater than or equal to B </li></ul><ul><li>A ≤ B A is less than or equal to B </li></ul><ul><li>(The small end is near the smaller number, the larger end is towards the larger number) </li></ul>
12. 12. Review Absolute Value <ul><li>The absolute value of any number is the number of spaces it is from zero on a number line </li></ul><ul><li>|-36| = 36 negative 36 is 36 spaces from 0 </li></ul><ul><li>|15| = 15 15 is 15 spaces from zero </li></ul><ul><li>*Remember that it only applies to what is inside the brackets so… -|3| = -3 </li></ul>
13. 13. Comparing Real Numbers Choose the correct symbol to make each statement true <ul><li>-26 ___ 26 </li></ul><ul><li>10 ___ 5 </li></ul><ul><li>-3 ___ -3 </li></ul><ul><li>2 ___ -46 </li></ul><ul><li>7 ___ -3 </li></ul><ul><li>8 ___ 16 </li></ul><ul><li>99 ___ 296 </li></ul><ul><li>6 ___ -6 </li></ul><ul><li>2011 ___ 2010 </li></ul><ul><li>405 ___ 401 </li></ul><ul><li>5 ___ |-7| </li></ul><ul><li>|98| ___ |32| </li></ul><ul><li>|-101| ___ 2 </li></ul><ul><li>|-3| ___ 7/2 </li></ul>
14. 14. Review The Coordinate Plane <ul><li>The coordinate plane allows us to locate points in 2 dimensional space (2D). A point is represented by an ordered pair (X,Y). </li></ul><ul><li>The coordinate plane consists of two number lines, one horizontal and one vertical. The horizontal line is called the X axis. The vertical line is called the Y axis. </li></ul><ul><li>The ordered pair tells you a point’s distance from zero on each number line. </li></ul>
