Quadratic Prezi

You are going to put together a presentaition on how to solve a quadratic equation, by graphing, factoring and using the quadratic formula.

Phase 1: Graph your quadratic, then take a picture of your work, be sure to show your table of values, and your graph. then plug in your equation to grapher and have grapher graph your quadratic( screen shot two pictures from grapher, one a zoomed in shot of the vertex and another shot of the vertex and where the x intercepts)

Phase2: Solve your quadratic by factoring, type this part out on the prezi

Phase 3: Solve your quadratic by using the quadratic formula, then take a picture of your work be sure to write clearly so you or others can read your work.

Phase 4: Find three ways the quadratic formula is used outside of a math class, take pictures of this, and include in prezi.

Phase 5: Put together your prezi,

Group the graphing part together.

Group the factoring part together

Group the quadratic formula part togehter, take a picture of the quadratic formula of the internet and put in this group with your work

Group where this is used outside of class together.

Phase 6: Present to class

Vimeo Project:

Keynote on what the definition of Absolute Value

Phase 1: Two slides one on the definition of absolute value, with pictures, then where the concept is used, besides math class.

Phase 2; Video yourself or your hand solving an absolute value equation an absolute value inequality.

Phase 3: Put video on your keynote, then export video as a quick time, then upload to vimeo, send me the link.

Cell Phone Plans and texting "Whats the best deal"

In this project you will anaylze cell phone plans for minutes and for texting and find th best deal. These plans are all for single person coverage, I am not concerned with Family plans.

Step 1: Answer all the questions in your notebooks both the cell phone and text plan, be sure to show work.

Step 2: Put questions 1,2,3 and 5 of the cell phone project into a key note, include on each slide the question and your work.

Step 3:Film yourself showing how to solve question 3 of the text messaging plan, then put this video at the end of your keynote.

Step 4: Make sure your work is correct and sound is good on your video, make sure you solve everything correctly. If your not sure ask.

All info came from []

**Cell Phone Project** You will solve all problems, then put your work in a keynote, along with videos.



7. After how many minutes does 450 plan become more expensive then the 900 plan, use substitution or elimination to solve and record your self solving the problem?

8. After how many minutes does the 900 plan cost more than the 1350, use substitution or elimination?



1. A texting plan consists of a fixed cost( the monthly fee) and a variable cost ( charge for going over your texting). Find a linear function that gives the totla cost of each plan when x extra texts are used both in and out.

2. Using the cost functions from above find how much it would cost using 300 and 600 texts per plan. Then determine the best plan for each level.

3. At what level does the unlimited plan text plan become cheaper than the 500 text plan.

Extranormal Project

You are going to make a cartoon using the website extranormal

you need to have two characters discussing the concept of graphing, pick a topic from below. graphing coordinates, lines slope intercept x and y intercepts

Now you will write a script where the two characters are discussing this concept. Length needs to be 1 minute 30 seconds. Talking the whole time, no dead space or long pauses.

25points. Web address: []

Due Date T0 Be Announced: TBA

Keynote Project: Make a keynote for the Real number system. Real Numbers Irrational Numbers Rational Numbers Integers Natural Whole Make a slide for each class of number, on each slide you need to have the definition of each class of number and 3 examples. On each slide you must have transitions between each text box and transitions moving from slide to slide. You must have a song playing throughout the keynote.

Quadratic Project

Understanding Quadratics, and the purpose of there existence. The purpose of this project is to understand why the quadratic equation exists. To understand this equation you will be completing a series of tasks that will develop your understanding of this mysterious formula. You will be researching the main contributors of this formula, looking at where the quadratic formula is used in “real life”, making videos, explaining the quadratic formula. Once complete you understand the true power of this battle station, I mean this formula. There will be 5 phases to this project these are all described below.

Phase 1: 20 points: Two Days: You are going to research the main contributors of the quadratic formula, choose 2 of the seven people or groups on the following page to tell me something about them. You need to write two paragraphs with five sentences or more per paragraph per person or group. 1. what century were they alive, 2. where did they go to school 4. what math has been attributed to that person or group, 5. who was this person trained by 6. what famous mathematicians were descendants of this group. Be sure to cite where the information came from, use you own words do not copy and paste. Post all information on your wikispace.

List: Babylonians Brahmagupta Mohammad bin Musa AL-kwarismi Abraham bar Hiyya Ha-Nasi Henry Heaton Yang Hui Liu Yi

Phase 2: 55 points: Three Days: You are going to discover where this is used in “real life” The first part of this phase is you will learn how to maximize area. Answer the following three questions explain your work and reasoning on you wiki, retype each question and solve. Here is a website that will help

[]

1. Suppose a farmer has /come ask me/ yards of fencing to enclose a rectangular field. What is the largest area that the farmer can enclose? (10 points)

2. The owner of a ranch decides to enclose a rectangular region with /come ask me/ feet of fencing. To help the fencing cover more land, he plans to use one side of his barn as part of the enclosed region. What is the maximum area the rancher can enclose? (10 points)

3. A farmer wishes to enclose a rectangular region bordering a river using /come ask me/ feet of fencing. He wants to divide the region into two equal parts using some of the fence material. What is the maximum area that can be enclosed with the fencing? (10 points)

Part two of Phase 2 is to solve the problems that involve projectile in motion. The formula you will be using to solve these problems is below: s(t) = –gt2 + v0t + h0 Describe what the letters g, t, v and h represent. (5 points) Here is a website that will help: []

Now use the formula and website to solve the following 2 problems. Copy and paste the problems to your wiki and explain them step by step.

1. Some fireworks are fired vertically into the air from the ground at an initial velocity of /come ask me/ feet per second. Find the highest point reached by the projectile just as it explodes. (10 points)

2. A ball is thrown vertically upward with an initial velocity of /come ask me/feet per second. If the ball started from a height of 10 feet off the ground, determine the time it will take for the ball to hit the ground. (10 points)

Phase 3: Three Days: 30 points You will be given a quadratic Equation; you will come and get your equation from me when you reach this phase. 1. You need to explain what does it mean to say “ solve by graphing” once you have this written on your wiki you will solve the quadratic by graphing. (10 points) 2. You need to explain what it means to say “solve the quadratic by factoring.” Once you have this written on your wiki you will then solve the same equation by factoring. What do the solutions represent after factoring a quadratic (10 points) 3. Last you need to explain what it means to say “solve the equation using the quadratic formula.” Put your explanation on your wiki and then take your equation and use the quadratic formula to solve it. Show the step-by-step process in solving this, on your wiki. (10 points)

**Use google to find websites that will assist you in this phase.**

Phase 4: Three Days: 40 points The final phase of this project requires you to film yourself working out a quadratic using the quadratic formula. You can choose one of two ways to do this 1. you can video tape yourself at the board working out a quadratic using the quadratic formula and explaining step by step how to solve your problem. Or 2. You can use the website : []. Look up quadratics watch the one I did, you will be given your own to solve. You can use the tablets in the classroom to do this.

You must speak clearly and make sense when explaining, your problem. Needs to be less than 7 minutes. When done you will upload your video to teachertube, then embed your video to your wiki.
