Test Wed. 2/1

On Wednesday we'll have a short (about 30 minutes) test on Chapter 9: area and the Pythagorean Theorem.

Monday in class we worked on the review exercises on pp. 371-375. Your homework is to finish the review problems and prepare for the test.

HW due Mon. 1/30

In class we worked on the computer lab "Area investigations with Sketchpad." The homework is to do problems 6-8 at the end of the lab packet. (You do not need Sketchpad to do the homework problems.)

Students who were absent on Friday: You can download the computer lab packet from FirstClass. The lab can be done using either Sketchpad (available at school) or Geogebra (free download). Just ignore the program-specific tips if you're using Geogebra; you'll need to use the equivalent commands in that program.

HW due Fri. 1/27

In Chapter 9 Lesson 5 "Pythagorean Theorem," we did exercises 4-14 in class, and the homework is exercises 15-53.

Please go directly to computer lab 700 for class on Friday.

HW due Thu. 1/26

• Finish the problem sheet from class, "Areas of regular polygons."
  
• On pp. 362-364, do 9.4 exercises 30-53.
  

HW due Wed. 1/25

• On pp. 356-357, Lesson 9.3 exercises 35-59 and Set III.
  
• On pp. 360-362, Lesson 9.4 exercises 1-29.
  

Hw due Mon. 1/23

During class we did these exercises: on page 354, Lesson 9.3 exercises 6-14.

For homework, do these exercises from the beginning of Chapter 9:

• On pp. 340-342, Lesson 9.1 exercises 7-12, 25-34, 46-55.
  
• On page 346, Lesson 9.2 exercises 11-17.

No HW due Fri. 1/20

Since we just had a test and this may be a busy night for your other courses, there's no homework tonight. Tomorrow we will start Chapter 9.

Test Thu. 1/19

We will have a test Thursday on transformations, symmetry, tessellations, and polyhedra.

In class Wednesday, we worked on a set of review problems. Your homework is to finish and check the review problems, and study for the test.

HW due Wed. 1/18

Finish the problem set "Archimedean Solids (Continued)."

HW due Thu. 1/12

Finish Wednesday's problem set, "Archimedean Solids."

(There was no homework due Friday 1/13.)

HW due Wed. 1/11

• Finish whatever remains of the problem set from class, "Polyhedra with Regular Faces."
  
• Hand in your tessellation mini-project (see previous assignment) on Wednesday if you haven't already.
  

Mini-project due Mon. 1/9 or Wed. 1/11

Read sections 1 through 7 of Tessellations by Recognizable Figures from the site Math and the Art of M.C. Escher. Then choose just one of the tessellation strategies and make your own tessellation design. See today's class handout for more details of what is expected and how your work will be evaluated. This assignment will count as a mini-project and may be handed in either Monday 1/9 or Wednesday 1/11.

Class Fri. 1/6

Here are links to web pages from which I showed you excerpts during class on Friday 1/6:

• 14 tiling patterns for convex polygons (note: as of this writing, the school filter is erroneously blocking this site so it can only be accessed outside school)
  
• Photographs of tessellation tilings in Cairo
  

HW due Fri. 1/6

Handout problem set "Tessellations - Day 2", which has a required part and an optional part.

HW due Thu. 1/5

Finish today's problem set "Regular Polygon Tessellations."
