Tuesday March 31 - HOMEWORK

Assignment: Worksheet, solve for S

Details: For both triangles, you need to solve for S. See the photo below for how to set up the ratios. Remember, you are doing the up&down line over the bottom line, for each triangle. Please look at the following diagram if you are having trouble setting up your ratios. In each picture, the green triangle is the small one and the orange is the big one. Note the green and orange ratios on the side.

To solve the first ratio you will need to cross multiply.
15(s+25) = 25x20

Remember to multiply 15 times everything inside the parentheses.
15s + 375 = 500

Then subtract the 375 from both sides so that you have letters on one side and numbers on the other.
15s = 125

Then divide by 15 so we know what S equals
S = 8.3

Solve the 2nd triangle the same way.

Friday March 20 - HOMEWORK

Assignment: rough draft of POW 19 (p. 455)

1. Subject of Exploration: What are we learning about? How does this apply to what we are learning in class? (angles? shapes?) What type of real-world problem could we solve using these skills?

2. Information gathering.
Include at least 4 pool tables (2x3, 2x4, 3x4, 3x5)

3. Results. What did you find? Does the ball always end up in a pocket? Which pocket? Did you find any patterns between the number of bounces it takes on different size tables?

4. Evaluation. Did you like this experiment? Why / why not? Ask a question about this topic,

Due: After spring break

Friday March 13 - HOMEWORK

Assignment: Homework 20 p. 459


Draw rectangular pool tables that measure:
And more if you like...

Start in the bottom left corner.

Draw your lines diagonally through the squares, to make sure all lines are 45 degrees.

Count how many lines it takes to get the ball into a pocket.

Here is an example of a 2x5 table. I started in the bottom left with the blue line.  I kept going until it finally got to a corner (pocket). Each line is a different color so you can count that there are 6 different lines.
The answer for this would be: 2x5 - 6

Assignment: Final Draft of POW

Details: Read my comments on your rough draft and fix anything that needs to be fixed. If you didn't have a question, make sure you include a question that is related to the topic.

Due: Tomorrow in class

**If you didn't finish your quiz in class, you can finish it for homework**

Friday March 6 - POW 18

Assignment: Rough Draft of POW 18 (p.438)

1. Problem Statement. Write the problem in your own words. You can find the problem at the end of the POW. ("Suppose three lengths, a, b, and c...)
2. Process: Explain what we did in class (using the pipe cleaners, listing lengths that worked and didn't work, looking for patterns)
3. Solution: Only answer the 2nd question (the problem statement). Explain in words, then use the > or < signs to make your condition.
4. Evaluation. Did you like this project? Why/why not? Think of a question about this project.

Remember! For the rough draft, you get 10/10 if you do all the parts, even if your answer is wrong. Just show me that you tried :)

Due: Monday in class

Monday March 3 - NO HOMEWORK

No homework tonight. We will try and get our work done in class this week, so you don't have to do any homework on testing week.

If you want to get started on something, you can start the POW we worked on in class (POW18)
