I had too much planned for today. We looked at the geometry concepts of transformations and geometric relationships. We didn’t cover all that I had planned in every class, but each class had a worksheet on Objective 4 for homework. Here is today’s PowerPoint.  (Click on the link or the slide to get a bigger view.)

Today we reviewed algebra concepts of patterns, equations, and expressions. Homework today was a worksheet over objective 4. 5th Period did page 572, #1-6 from each section instead. 7th Period did the book work and the worksheet. Here are the This album is powered by BubbleShare – Add to my blog

We began our review for the ARMT today. We focused on the Number and Operation strand. We reviewed fractions, integers, decimals, percents, and order of operations. Tonight’s homework is a worksheet practicing Gridded Response questions.

Here is a slideshow of today’s PowerPoint.

Test tomorrow over transformations. Check these links for games about translations, reflections, and rotations.

Be sure to understand the following words:  translation (slide), rotation (turn), reflection (flip), clockwise, counter-clockwise, x-axis, y-axis, 90 degree turn, 180 degree turn.

All three of my children have had the flu, so I have not been at school in over a week.  I tried to go today, but I received a phone call from day care saying my son was throwing up before 1st period had barely begun!  On the way to pick him up, my daughter’s school called to say that she was not doing well, so I brought her home too.

I  have had a productive day.  While the children slept I graded mountains of papers!  I am caught up except for the Test Ready sheets they have done this week.  If I could just get to school to put my grades in STI, then all would be good!

A dart is thrown at random at each of the dartboards below.

(I will try to upload the pictures later.  You should have them on your worksheet.)

a.  For each dartboard, what is the probability that a dart will land in a region marked A?  A region marked B?  A region marked C?

b.  For board 1, what is the probability that a dart will land in a region marked A or B?

c.  For board 2, what is the probability that a dart will not land in region C?

Same rules as number 3.

Tioko and Dione are using the spinners from the Making Purple game to play a two-person game.  They take turns spinning the two spinners.  If the colors on the two spinners make purple, Dione scores.  If they do not make purple, Tioko scores.  For this to be a fair game, how many points should Dione score when the spinners make purple, and how many points should Tioko score when they do not make purple?

Post your answer as a comment.  Same rules as number 3.

In the Gee Whiz Everyone Wins! television game show, members of the studio audience draw a block randomly from a bucket containing 2 red blocks, 1 yellow block, and 3 blue blocks.  If a blue block is drawn, the contestant wins $5.  If a red block is drawn, the contestant wins $10.  If the yellow block is drawn, the contestant wins $50.  The block is replaced after each draw.

a.  What is the probability of drawing each color?

b.  If 24 contestants draw a block from the bucket, how much money can the game show expect to pay out?
