| HW # | Problems Due | Due Date |
| Weeks 1-4: Geometry, Ch 9 |
| HW #1 |
- 1. Read thru Section 9.1 (p563-578), looking for vocabulary words.
Write down definitions to any of the words you find on your Geometry Vocab sheet.
(Many of the words won't appear until later sections, so you can leave them for now).
Add another page to your geometry vocab sheet, including any vocab words you find
interesting or new, along with their definitions. You don't have to include every
term in the chapter, but find ones that are new to you or especially important, or
that you would not have been able to define without looking up. (This will not be turned in.
Keep as a study tool.)
- 2. WB: 9.1, 2-8. (WB will be turned in for credit)*
*You may rip out pages from your WB, or make photocopies, or write solutions on separate paper,
being careful to label the section and problems. You may not turn in the whole book.

| HW #2 |
- 1. TB 9.1 (p583): 4, 10, 11-20, 24-26, Writing and Discussion #2
- 2. TB 9.1: 22, 23, 28 (these problems create a separate nifty big problem, involving “if I have n lines, how many intersections might I have?”)
| Tues, Oct 12th |
| HW #3 |
- WB: 9.2: (p264-271): 1-5 and p 273 Follow-up questions 2, 5
- TB 9.2: (p599) 2-7, 10, 12, 14, 15, 22, 23
| Tuesday, Oct 19th |
| HW #4 | HW 4:
- TB 9.2: 28-30.
- TB 9.4 : 5, 6, 11, 13-18, 24, 25
- WB 11.2: #1-3 (p333) Escher Tessellations
- Follow-up to Escher from WB, try Escher with a Regular Hexagon .
This was handed out in class on Thursday. Bring lovely pictures to share with your classmates
on Tuesday. Perhaps a nice fall or halloween theme?

| Midterm |
The exam will cover Ch 9, including vocabulary about angles, polygons, tessellations, symmetry, and prisms and pyramids.
In addition, be prepared to answer questions about patterns (such as the toothpick problems or line crossing problems) and about proofs.
You are responsible for the proofs of:
- Sum of interior angles of a triangle,
- sum of interior angles of a polygon,
- sum of exterior angles of a polygon,
- why there are only 3 regular tessellations.
Keep in mind that you can use the sum of the interior angles of a triangle to help with the proof of the sum of the interior angles of a polygon, but you cannot use the interior angles of a polygon formula to justify the sum of the angles of a triangle. This would put you in a vicious loop of assumptions.

| HW #5 | HW #5
- Read section 9.3 and learn how shapes are named.
- TB 9.3: (p615) 2-5, 8-11, 24, 25, 26, 34 (justify your reasoning for #34), 37, 38
- WB 9.3: #4 “Net Patterns for Cubes” (handed out in class)
- A net pattern is a single image that can be cutout and folded into a specified 3-D shape.
Make Net patterns for hexagonal prism and square pyramid. Recall how there are multiple nets that make the cube.
Create two distinct nets for each shape. The nets you turn in should be flat pieces of paper, not assembled.
IF YOU MISSED CLASS ON THURSDAY, then you missed an assignment that was turned in during class.

| Tues, Nov 2nd |
| HW #6 | HW #6:
- Geoboards Part I Worksheet
- Find the area and perimeter of all of the geoboard shapes on Geoboards Pages 1 and 2.
- Find the area of the geoboard shapes on Geoboard Page 3. As you work, focus on what new strategies are required for these new problems. Be prepared
to share these strategies on Tuesday.
No digital copy of this assignment is available. If you miss Thursday's class, contact me. | Tues, Nov 9th |
| HW #7 |
- Geoboards Page 4: Find Area only.
- TB 10.2: 13-19, 21. Carefully show your work for both area and perimeter for each problem. You are encouraged to imagine that complicated shapes are built from simpler ones, like triangles and rectangles.
- Read thru all of the Geoboard Lesson Sequences created by your classmates.
Type a 1 page reflection on what you notice about the lessons (1 page total, not one page per lesson). What do the lessons have in common?
How are they different? What did you notice or learn through this actitity? etc.
| Tues, Nov 16th |
|
| HW #8 |
- TB 10.3: 2, 5, 7b, 8a, 9 (look up book formulas), 10, 11a, 12a (for 7-12, find volume AND surface area), 15, 16, 29, 32
If you missed class on Thursday, Nov 18th, you missed a quiz. Come to office hours on Tuesday to make up the quiz.
| Tues, Nov 23th

| HW#9 | Click here for the Construction HW
If you get stuck on one or two of the constructions, the internet would probably be a better resource than the textbook.
Phrases like "geometric construction" or "greek construction" should help your search.
| Tues, Nov 30th |
| HW #10 |
TB 11.1 (p745): 15-21, 28-33, 39-42
Try all the problems. If there are some you struggle with, bring questions to class on Thursday. Each small group from class is responsible for being ready to
help you with a subset of the problems from the list.
| Thurs, Dec 2nd |
| Solution to pyramid | Question: If you build a pyramid with
base 8 by 12 inches and height 5 inches, what is the surface area? For 3 possible vertex angles, the solutions are given in the following file:
