Winders Wonderful World of Math

Note for ALL of my students

If you will scroll back through my previous blogs, you will find several excellent tutorial videos that may help you as you review for your mid-term. Most of them are labeled for 2nd and 3rd block or 4th block. 2nd and 3rd blocks will have the same mid-term and 4th block will have a different mid-term.

2nd and 3rd block--video on how to find a linear equation using a graph (for Mid-term)

 

Here is a video that shows how to find a linear equation by looking at a graph. To write the equation in slope-intercept form, you need to know the slope and the y-intercept. There will be four questions on mid-term where you will see a graph of a linear equation and then have to pick the correct equation in slope-intercept form

Mid-term review handouts for my 2nd and 3rd Block classes

I have linked our mid-term review handouts below, just in case you have misplaced the ones I gave you in class. The handouts are due on Tuesday, Dec. 20th. If you want to take part in the mid-term incentive I offered, your review handouts must be complete and at least 80% accurate, and turned on time. Also, I expect your behavior to be appropriate while we are reviewing for the mid-term and during the mid-term. Please remember that the review time during class is when you should ask for my help. I will not "teach" you how to work problems during the mid-term. If you do not understand then, it is too late to ask for help. If you talk, make noises, or disrupt the mid-term in any way, you will lose your mid-term incentive. Do you understand the incentive?  Here is how it works: If you earn the incentive by doing the things I described above, I will take the square root of your mid-term grade and multiply it by 10. For example, if you make a 54 on the mid-term, the square root of 54 is 7.3 and 7.3 x 10 = 73, so you can fail the mid-term with a 54 and actually pass with a 73.  Sweet!  The review handouts are linked below.

Example of a standard deck of 52 playing cards for 2nd and 3rd block

I googled "deck of 52 playing cards" and found this example. You need to make sure you understand how a deck of cards is set up. There are 52 cards in a deck and these cards are divided into 4 suites--hearts, diamonds, spades, and clubs. So each suite has 13 cards (52 divided by 4 = 13). Each suite contains the following:  2,3,4,5,6,7,8,9,10, Jack, Queen, King, Ace, so there are 4 of everything in a deck.  When you have a dependent or overlapping problem, you must remember not to count a card twice. For example, if you have a question that says "What is the probability of selecting a Jack or a diamond given a standard deck of 52 cards?", you must remember that there are 4 Jacks, so the probability of selecting a Jack is 4/52. There are 13 diamonds, BUT you have already counted the JACK OF DIAMONDS, so DON'T count it twice, just use 12 diamonds instead of 13, so the probability of selecting diamonds is 12/52. Since the word "or" means ADD in probability you would add 4/52 + 12/52 = 16/52 or simplified to 4/13.

This is a typical problem that you might see on a Post test or the EOCT. You are expected to know how to add, multiply, and simplify fractions. This was part of your 5th and 6th grade Math standards, so if you have trouble with it, you really need to find online website that can help you practice working with fractions. Math is like every anything else in life--it would want to improve, you have to be willing to work hard and practice, practice, practice.

Don't forget that we have a quiz on Friday, Dec 2 over Compound Probability. It will include the vocabulary words as well as some probability problems. This is YOUR chance to bring up your math grade!!!
