DAY 1 To Turn in: Signed, Filled out Last page of the Syllabus (torn off) Warmup ( At your desk, By yourself, Silently ): 2 minutes Jot down examples of all of the different types of numbers you can think of, and name the “type” for each that you write. Think of any numbers you can! For example: 3 – a prime number, 2.3 – a decimal number, but also a rational number

DAY 1 PRAYER

DAY 1 Share some responses! Types of numbers: Where do our numbers come from? Sets of numbers - what are all of the different types of numbers? 1. Natural numbers 2. Whole numbers 3. Integers 4. Rational Numbers (think “ratios” – fractions) 5. Irrational Numbers 6. Real Numbers 7. What’s next? – stay tuned…

DAY 1 Whiteboard practice! Be sure to write clearly on the boards. Please write LARGE and CLEAR! 1. True/False: An integer is a rational number. 2. True/False: A rational number is an integer. 3. True/False: A number is either rational or irrational, but NOT both.

DAY 1

Rules/Procedures – on white board, write the most important rule to you in any classroom 1. Top three rules on the front wall 2. OVERALL: Raise Your Hand! 3. A time for listening, a time for talking Responsibility for actions – regardless of intent 1. Late – better have a pass or a tardy slip! 2. Materials – have textbook, notebook, binder, graphing calc, pencils, pens every day! – if not, deduction in “Demeanor” grade 3. Homework – on time and completed, not partial – if not, no credit… must be responsible, ask for help after school, at lunch, etc.

DAY 1 4. Cell Phones – even if they beep this year, I’m taking them. Responsibility – turn them off! If not, I will keep them for two days (more if repeat offender) 5. Backpacks/other belongings – outside – if not, I’ll confiscate them 6. Changing Rooms – light chatter ok, but should be silent upon entering any of the buildings or classroom so as not to disturb other meetings and classes 7. Emergencies – remain calm! Stay SILENT and listen to teacher. Why is this also important in a drill?

DAY 3 PRAYER

DAY 3 One final pattern: THINK/WRITE – What are the next two figures in the pattern? (2 min) PAIR– How many blocks are in the 100 th pattern? (3 min) SHARE – What is the “rule” for this pattern? (rule means “formula” or “equation”)

DAY 3 Linear patterns – have the same rate of change from data point to data point Rate of change = SLOPE What does this mean? - The difference between each output value is the same RELATIVE TO the difference in each input value - We can always start a linear pattern problem by trying to find the SLOPE.

DAY 3 EXAMPLE: Linear Data problem InputOutput ? ? We only pay attention to the data values that have the same difference in input values, so (12,30) does not factor into the creation of our pattern here.

DAY 2 Last Week: Mass (g) g g g g g

DAY 2 Last Week: Mass (g) g g g g g Problem: We didn’t all get the same slope, but our data “looked” linear on the graph. Welcome to the real world! Not a perfect fit. We must now find a way to model the data as best as we can.

DAY 2- LINEAR REGRESSION EQUATIONS Let’s use our calculators! To plot the data on your calculator: Click HereClick Here for step by step instructions. Take notes on these!

DAY 2 - LINEAR REGRESSION EQUATIONS This Week: Mass (g) g g g g g

This Week: Mass (g) g g g g g DAY 2 - LINEAR REGRESSION EQUATIONS

DAY 2 FUNCTIONS - A function is a relation in which each element of the domain corresponds with exactly one element of the range. - A relation is a set of pairs of inputs and outputs.

DAY 2 FUNCTIONS As with any machine, we want to know exactly what happens when we “input” a specific piece of data. If you pressed the “print” button on the printer, and the printer might print OR it might turn off, that printer would not be very effective. This is a relation, but NOT a function. (Ex 2)

DAY 2 FUNCTIONS - To determine if it is a function: 1. Numerically (table) – refer to last slide. If each distinct input only points to ONE output, it is a function. 2. Graphically – the vertical line test. (next slide) 3. Algebraically – That is our mission this whole year! (When I plug in ANY value to the function, do I get a MAXIMUM of ONE possible output?)

DAY 2 FUNCTIONS - Vertical Line Test: to test if a graph is a function - If a vertical line can be drawn that touches MORE than one point on the graph, the relation is NOT a function. NO YES

Finding Intercepts of equations. 1. Y-intercepts – Where the graph crosses the y-axis. - All y-intercepts have an x-coordinate of 0. - To find the y-intercept in an equation, substitute 0 in for x. - y-intercept: (0,b) 2. X-intercepts – Where the graph crosses the x-axis. - All x-intercepts have a y-coordinate of 0. - To find the x-intercept in an equation, substitute 0 in for y. - X-intercept: (a,0)

Graph the line.  “ZOOM” then “6” OR “GRAPH” 3. “TRACE” – this allows you to type in an x-value and see its corresponding y-value  “TRACE”, then “0”, then “ENTER” - X-intercepts – 1. Do steps #1-2 from above 2. “2 ND ”, then the “TRACE” button 3. Select choice “2:ZERO” 4. Scroll to the left of where the x-intercept is on the graph using the left and right arrows, Press “ENTER”. 5.
