VanDrisse's Journey

Please note, I had a typo on #5….if should read “x varies DIRECTLY with y.” I’m sorry I typed inversely in by accident. I worked through the six problems and attached them for you to see how to solve those six problems. Number 6 was tricky in the sense that you didn’t really need the y = 12 information in order to solve the problem.

Classwork:

• First we went through last night’s homework and answered questions you had, and I showed you the proportion method for solving problems like #13 and #14 from last night’s homework….for those of you who love proportions I think you found that method to be easier )
• If you brought your textbook to class today, I collected it from you so you have one less book in your locker…if you didn’t bring it to class today, try to bring it tomorrow unless you are using it to review for the final math 6 exam next week
• Finally we played mathketball, and almost everyone in all class had a chance to come up and shoot today….we had 15 review problems to try, but we didn’t get through all of them in any class. If you want to re-try any of the problems, I’ve attached the power point for you. The answers are on the last slide for you!

Homework: Study for tomorrow’s Direct Variation Test. I will post the solutions to the 6 review problems from the half sheet of paper in another post in case you want to practice a little tonight )

Classwork:

• We did a quick review of what the graph from Calculating Payroll should’ve looked like and talked about what your x-axis and y-axis should have been labeled
• We ran through five real life examples of how to write equations of direct variation situations (Jing the Juggler sheet). The only difference in these equations is we used different variables in the equation. We still multiplied the constant and the independent variable to get the dependent variable.
• Next, we started your homework assignment. We did one problem from each of the four sections together, and you should have written down all four of the examples so you know exactly how to solve each of the problems.

Homework:

1. Finish the 14-question half sheet
2. Direct Variation Test – Friday (if you want to review the direct variation power point, download it here directvariation-powerpoint1

Classwork:

• We worked on reviewing direct variation concepts by working on “Calculating Payroll.” In class we worked on setting up #1 together to make sure you knew how to draw the table and knew how to fill in the values. You then proceeded through the assignment at your own pace while I helped you with whatever questions you had. Some of you finished at the very end of class which is great because you don’t have any homework :0] If you didn’t finish in class, be sure it is done by class time tomorrow because it will count as a class work grade because we spent so much time on it in class today. The activity review tables of direct variation, graphs of direct variation, and how to use the direct variation equation to solve for the constant of proportionality.

Homework:

1. Finish “Calculating Payroll” if you didn’t finish in class   calculating-payroll
2. Unit 8: Direct Variation Test – Friday, May 1 (that’s this Friday….see Monday’s blog for a power point to help you review

Classwork:

• Some classes had already started, and some classes just began, but we finished the half sheet with 5 tables of values today. You were to graph the data points from the table, then state whether or not it was a direct variation. If it was a direct variation, then you were to find the constant and write an equation to represent the graph/data table.
• You were given a 6-question worksheet addressing direct variation

Homework:

1. If you didn’t finish the 5-question half sheet in class, complete it for homework…it is going to count as a class activity grade because you did spend a lot of classtime working on it
2. The 6-question multiple choice direct variation worksheet
3. Unit 8: Direct Variation Test – Friday, May 1…I’ve included the power point from which you took notes at the beginning of the chapter…you can try some of the practice problems from it to help prepare for Friday’s test directvariation-powerpoint

Classwork:

• I signed your progress report sheet, and if you earned a “D” or an “F” you received an individual print out of your grades. If you received the individual print out of your grade, you must have your parent/guardian sign it and return it to me by Tuesday. If you don’t have any individual print outs, that’s great news because you have A’s, B’s, and C’s, but you still have to have your parents sign the yellow half sheet with your grades thus far for every class filled in by your teachers. The yellow sheets must be signed and returned to homeroom by Tuesday.
• Period 1 – you practiced graphing direct variations, finding the constant of proportionality from tables, and writing equations of direct proportions. If you didn’t finish in class today, you will have the opportunity to finish in class on Monday.
• Periods 2, 3, & 4 – You were further ahead than period 1, so we went outside and practiced our multiples by playing “Buzz.” I found it odd every class chosse to do multiples of 3 first….3rd period had fun playing “Buzz Whiz” with multiples of 2 and 5….it was funny to watch you guys with that game.

Homework: NONE…have a great weekend!

I was very impressed with how many of you in my home room took the time to work out the problems on the math portion of the CRCT this morning! I was also impressed with the people who came to me this morning just to make sure they knew how to do certain types of problems…you were being very conscientious and you wanted to do well and I’m sure you did!

Classwork: We talked about the CRCT and how well you think you did. Afterwards we took it easy today, and we’ll get back to Direct Variation tomorrow…I know you can’t wait!

Homework: NONE )

Due to the CRCT occurring today through next Monday, classes are shortened, but you will be going to every class every day except for Connections (that will rotate every other day) )

Classwork:

• We finished up the CRCT packet and any questions you might have in regards to Thursday's math portion of the test
• You were given a half sheet with 5 tables of values. Your task was to first graph the info from the graph. Then you had to state whether it was or was NOT a direct variation by looking at the graph. If it was a direct variation, then you had to find the constant and write the equation for the given values in the table. We took everything we've learned for the past week or so and started pulling it all together!

Homework: NONE – Rest for tomorrow's LA CRCT, and if you want just a little more practice, feel free to jump onto the Skills Tutor or USA Test Prep websites for practice!

Classwork:

• We checked the CRCT packet #64 – #82 and discussed a few of the problems
• We went through a direct variation graphing sheet together. You had to fill in tables of values and then graph the ordered pairs which were solutions to the equation. We also had to write equtaions from looking at a given graph….to do this you pick an ordered pair from the given graph and substitute the x and y values into y = kx (the direct variation equation). Then, solve for the constant and substitute into the equation and keep in the form y = kx where k is a number, but x and y are still in the equation. Keep the worksheet to refer to tomorrow in class when you are set free to solve problem on your own )
• With the remaining time you were asked to work on the remaining problems in your packet so you had as little homework as possible!

Homework: CRCT packet #83 – #99
