Geometry+Wk+2


 * Geometry:**

Week 1: Geometry basics Week 2: More Geometry basics Week 3: Graphing Week 4: Applications Week 5: Geometry and Probability

Therefore, I must prepare 4 days of material for each week and 5 days of “filler” material. I recognize that 5 days of filler probably will not be necessary, but this material will not expire. Right now, the filler material I have in mind is:

1: Puzzles and Riddles 2: Puzzles and Riddles Part 2 3: Pop Psychology 4: Newcomb’s Paradox + Prisoner’s Dilemma 5: Algebra II and Geometry video games (on a CD, left over from last year) 
 * Geometry:**

Week 1: Geometry basics Week 3: Graphing Week 4: Applications Week 5: Geometry and Probability
 * Week 2: Perimeter, Area, and Volume**


 * Perimeter, Area, and Volume:**

__Monday__: Students are just coming back from the weekend and could use a quick refresher. Review types of triangles and quadrilaterals. Then, move on to perimeter and circumference. Use the formula P = side1 + side2 + … + side //n// for polygons and C = 2πr for circumference of a circle.

Teach how to find the perimeter of a regular polygon, an irregular polygon (such as a trapezoid), and a circle.

For polygons, just add up all of the sides. For a circle, C = 2πr.

This shouldn’t be difficult. Maybe bring in some shapes, string, and a ruler to find perimeters of unusual objects.

//Practice finding perimeters and circumference//.

//Homework//: Make a short worksheet and quiz tomorrow on finding perimeters and circumferences.  __Tuesday__: Check HW (credit) and ask if anyone has any questions, quick perimeter review. 10 minute Quiz. Should take about 20 minutes total.

Today: Area of a triangle, square, rectangle, trapezoid, and circle. Also, show the old way of estimating how to find the area of a circle – by drawing a polygon on the inside and outside, finding their area, and then adding them up and dividing by 2.

Triangle: ½bh Square: b2 Rectangle: l*w Trapezoid: ½(b1 + b2)*h Circle: πr2

//Practice finding the area of triangles, some quadrilaterals, and a circle,// //and// //the area of chocolate bars.//

//Homework//: Make a short worksheet and quiz tomorrow on finding areas.  __Wednesday__: Check HW (credit) and ask if anyone has any questions, quick area review. 10 minute Quiz. Should take about 20 minutes total.

Today: Volume! Find the volume of certain chocolates, for example: Kit-Kats, Snickers, (insert some cylinder shaped candy (hat tamales maybe)), and Gobstoppers. All of the examples used in this case will be rectangular prisms, cylinders, and spheres. Bring in rulers or those bendy tape measurers. Tell students that if they can find the correct volume of the chocolate, then they may eat it.

Rectangular Prism: l * w * h Cylinder: πr2h Sphere: 4/3πr3

Test tomorrow! I will not be here for the test (surgery). __Thursday__: Test! 15 minutes questions and review. 45 minutes test.

No homework.  __Friday__: July 4th - all the students are gone!
