| HW # | Problems Due | Due Date |
| Weeks 1-4: Geometry, Ch 9 |
| HW #1 | Bring your spiral bound workbooks for the Thurs, Week 1.
- (To turn in) WB: (p.256-259) 9.1, 2-8.
- (not to turn in) 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.)
*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.
| Tues, April 5th
|
| If you missed class on Tues, April 5th, you missed a lesson on angles. Read section 9.1 for
vocabulary terms. Problems like 12-14 in section 9.1 will give you a flavor for what you missed in class.
For Thursday's class, each student is expected to bring a written proof for why the sum of the interior
angles of a triangle is 180 degrees. You will be sharing this in your new groups on Thursday.

| HW 2 |
Due Tuesday (not Thursday)
HW 2
- TB 9.1 (p583): 4, 10, 11-20, 24-26, Writing and Discussion #2 (p587)
- 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, Apr 12th |
| HW 3 | HW 3:
| Tues, April 19th |
| HW 4 | HW 4:
- TB 9.2: (p599) 2-7, 10, 12, 14, 15, 22, 23, 28-30 (explain your reasoning for 28-30)
- TB 11.2: 1-3 (we started this in class)
- Regular hexagons: Can we make Escher tessellations out of those?
- a) Create step by step instructions explaining how to make an Escher-style tessellation using the regular hexagon. Label important vertices and be specific about which sides go where. Create a beautiful picture of your tessellation.
- b) Using a regular hexagon, Create an example of a potential Escher shape that actually won’t tessellate. (As you were experimenting for (a), you may have found some examples already.) Use a picture to demonstrate how you know the shape won’t tessellate.
For both a) and b) attach the cutout pattern you create to your paper.
| Tues, April 26th |
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)
- TB 9.4 : 5, 6, 11, 13-18, 24, 25
The midterm will be Thurs, May 5th | Tues, May 3rd
| | HW 6 | Geoboard Area HW:
Finish the area (pages 1 and 2) and find the perimeter for all of the shapes on page 2, to the nearest tenth of a unit.
| Tues, May 10th |
| | Find the area of each geoboard for Page 3 of the geoboard activity. If you get
stuck on any, please bring your questions to class on Thursday. Extra copies are available outside my
office door.
| Thurs, May 12th |
| HW 7 |
- Geoboards pages 3 and 4: Find area only. Clearly indicate your answers on each problem.
- 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 the section to find
circle formulae.
| Tues, May 17th |
| | For Thursday's class, each group should have two pyramids built, both with
base 3 and 4 and height 2. The pyramids should have different locations for the top vertex.
|
| HW 8 |
If you missed class on Thurs, May 12th, you missed a quiz. Contact me about making up the quiz. I have time
available on Tuesday.
- Create a net for a square pyramid with base 5 cm by 5cm and height 3 cm. Clearly label
the lengths on your net. You do not have to tape your net into a 3-D shape, since that will make
turning it in more difficult. Write brief directions on how to create your shape, noting in particular
where your use the Pythagorean Theorem.
Record the surface area and volume of your pyramid.
- TB 10.3: 2, 5, 7b, 8a, 9 (look up book formulas), 10, 11a, 12 (for 7-12, find volume AND surface area), 15, 16, 29, 32
| Tues, May 24th |

| | If you missed class on Tues, you missed a quiz. Contact me via email about making that up.
We also started ancient greek geometry, using only a straight edge and compass... no protractors or rulers.
If you were absent, please try creating the following shapes before the next class.
Shapes:
- 1. If you start with a line segment, can you make one twice as long? Half as long?
- 2. Perpendicular lines
- 3. Equilateral Triangle
- 4. Square
- 5. Two parallel lines. (Start with a line and a random point K off the line. Show how to make a line parallel to the first line, through K).
- 6. What other geometric shapes can you make? Make directions for each.
| HW 9 | Construction HW | Tues, May 31 |
| HW 8: Redo | If you did not like your score for HW 8, you may submit a new HW, consisting
of only the 5 problems from TB 10.3: 2, 8a, 8b, 12b, 14a. Some of these are from the old HW and some
are new. Submit clean new versions of all 5 to receive credit. Your new score will be based only on these
5 questions. Keep in mind that problem 2 has 8 distinct parts. | Thurs, Jun 2nd
| | Pyramid Practice | (For review, not to turn in)
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:
