Homework is to complete the attached worksheet 9.1
Today we categorized our 3 dimensional shapes into polyhedron versus non-polyhedron. Then we classified polyhedra into prisms and pyramids and they are always named by their base. Each student used marshmallows, toothpicks and/or uncooked spaghetti to make a specif polyhedron. Each student determined the number of faces, vertices, and edges. We put the data together and were able to see the Euler Formula relating these items: F + V = E + 2.
Homework is to complete the attached worksheet 9.1 Students completed the chapter 11 test. The chapter reviews were collected. We will be starting chapter 9 on Monday, May 13th. Enjoy the long weekend!
We went over the review packet in 2 teams and played Card Sharks. Test tomorrow, May 9th, on chapter 11.
http://www.flashgameshows.com/game-CS.html Today we went through 14 review questions on 11.1 - 11.3 and then students took the 11.1 - 11.3 Quiz. WS 11.7 was collected and students received a review packet of chapter 11.
Today we examined the equation of a circle with the center at the origin and saw its connection to the Pythagorean theorem (x^2 + y^2 = r^2). We also learned the general equation of a circle with a given center and radius. We were able to graph a circle given its equation. We completed our notes on 11.7 and tonight's homework is Worksheet 11.7. Quiz 11.1 - 11.3 is tomorrow, May 7th and the chapter 11 test will be this Thursday, May
Today we reviewed central angles and talked about how inscribed angles are half the size of the intercepted arc. We went through 10 examples in our notes. Students are to complete the Worksheet 11.5 (both sides) for homework. This will be collected Monday, May 6th.
Use the link below for more examples: http://www.brightstorm.com/math/geometry/circles/inscribed-angles/ I was out at the district STEM meeting today. The sub should have handed out notes for 11.3 and students were to complete them and do WS 11.3. Major arcs cover more than half the circle, minor arcs are less then half the circle and semicircle is exactly half a circle. The arc measurement in degrees is the same size as the central angle. There are 360 degrees in a circle.

Today we discussed the relationship between a tangent and the radius of a circle, they are always perpendicular. We completed our notes on 11.2 and students are to complete the Worksheet 11.2 (both sides). Some students turned this in today; however, it can be turned in tomorrow (May 2).
