How OLD is Mr. Brzenski???
For those of you who want to know how old I am, follow this riddle poem and see if you can figure it out. I always give math puzzles for my age. I start with hard ones and get harder as the year ends. So don't think it gets any easier.
"To find the age of me,
follow the steps for the fraction and see,
Pi's first digit on top,
Add the next 4 down below,
And my age, repeating, you'll see"
Its tough, and you probably need a calculator and the first few digits of Pi (look at your tracking sheet)

Extra Links on the Sidebar
Over to the right you will notice I added a new section to the web page titled "Useful Pages". There you will find a copy of both the tracking sheets in case you lose yours and want to print out your own.
Also included is a multiplication chart which has general rules about all of 7th grade math.
Below that are two links to graph paper. The first is regular graph paper you can print (1/4 inch squares). The second link, the one labeled "Metric Graph Paper" is what we use when the squares are all 1cm wide.
Hope these help.

Graphing
For homework today you are supposed to finish graphing sets 1, 2, and 3. If you mess up the graph paper and need new ones, look to the right and you will find a link to download a printable sheet of graph paper, or just CLICK HERE.
Hints for set 1:
#7) Peanuts are $0.50 for 1 pound
#8) Bananas are $0.25 for 1 pound
For set 2:
The graph should have hours along the bottom and miles along the side. Count by 100's on the miles. Skip spaces on the bottom between hours like you did on the first graph between pounds.
For set 3:
Same as for set 2, hours on the bottom and miles on the side. This time, the miles should go by tens.
Good luck, remember this is worth 8 points tomorrow.

Tuesday and the Book 2
Todays homework is:
Page 473 #12-20
Page 483 #26, 27, 29, 30
The first set of problems asks you to find the equation that goes with the picture. The first picture (#12) shows a line with a shaded in circle on -5, and then the shading goes off to the right.
All your inequalities will start with the letter "x". For #12, you know the shading goes to the right, and the circle is shaded in, so it must start off "x &ge ". And since the line starts at -5, the inequality must be x &ge -5
Be sure you finish the homework, tomorrow we will do some review of these and equations.

Monday, welcome Back!
Todays homework is page 479 #29-40. They are all like the classwork today. You have to write the question and graph the answer on a number line.
Helpful Hints:
#33 and #34 Both of these are written backwards. You can rewrite them forwards.
#33 5 > t-1 = t-1 < 5
#34 2 > p-8 = p-8 < 2
This works for #37 and #40 as well. Write the first part last, the last part first, and switch the sign in the middle.
Tomorrow we will do more difficult problems, and I will give you problems from the assessment test next Thursday.

Testing
I have found a bunch of dumb things I can put on the website. Like this, a countdown to when we take the state tests.

Friday
Todays grades are posted. They are current for the newest tracking sheet. Many of you did not do, or did not turn in the tracking sheet for this week. This is shown by a "mi" in the last column, which says the work is missing. Please turn in what you have to me the Monday we get back. Anything is better than a zero.
Use the spring break time to catch up on the extra credit. I will add a few more pages so the extra credit will be up to number 8. If you have 100% in the class, please do not do the extra credit, save it for some other time.
Have a good spring break.

Thursday for Friday
Today I was gone, so everyone got a review worksheet about positive and negative numbers. For periods 1,2, and 3, please remember to bring your homework and tracking sheet to class tomorrow to turn in.
Tomorrow we will be doing a graphing activity where you plot points, make pictures, and then measure angles.

Wednesday
The homework for today is all finding the AREA of circles. There is NO circumference, and no radius or diameter.
The area is = &pi &bull r2
The first half tells you the radius, so all you have to do is substitute it into the equation.
The second half of the worksheet gives you the diameter, so you have to cut those in half to find the RADIUS. Then, use the RADIUS to find the area of the circle using the above equation.
Tomorrow I will not be in class for periods 1-3. Be good, and you will get 5 points. I am just at a meeting, so I will return for 4-6. Sorry.

Monday and the area and perimeter
Todays homework is page d-56. The grades to the side are all current and your grades as of the classwork today.
Remember: Area of a triangle = (B x H)/2
Perimeter: Add all the sides (a triangle has three sides, no more)
Remember: Area of a triangle = (B x H)/2
Perimeter: Add all the sides (a triangle has three sides, no more)

Gone from computer
I am gone this weekend and this is the first I have come near a computer. The grades are not up yet. Sorry. They will be put up on Monday night. The triangles are taking longer to grade then I thought.

Finding the Missing sides
a2+b2=c2
Use this to find all the missing sides. For the homework, you will notice that all the problems on the page are missing side c. This means all your equations will have 'a' and 'b' filled in, with c missing. Just add the two on the left, and take the square root.
For a triangle with sides 9 and 12, filled into the equation it gives
92+122=c2
81+144 = c2
225 = c2
√225 = c
15 = c
Same thing for the other equations.

There is no homework today. For periods 1 and 6, be sure to bring your homework tomorrow. I will stamp the homework and the warm-ups when you return.
Tutoring will also resume on Wednesday. I apologize for missing yesterday, but I had a meeting to attend.
