Topics covered in this course include points, lines, planes, angles, proving theorems with deductive and inductive reasoning, parallel and perpendicular lines and planes, angle relationships, the equations of lines and slopes, types of triangles, properties of segments and angles, properties of congruent triangles, polygons, quadrilaterals, parallelograms, rhombi, rectangles, squares, kites, trapezoids, ratios and proportions, similarity, dilations, Pythagorean Theorem and its converse, the Law of Sines, the Law of Cosines, properties of circles and their tangent lines, arcs, inscribed angles and chords; equations and graphs of circles, perimeter and area of triangles, quadrilaterals, polygons, and circles; surface area and volume of prisms, cylinders, pyramids, cones, and spheres; symmetry, and transformations.

Materials: protractor, ruler, drawing compass, drawing paper, graph paper

Resources: CK12 Geometry Flexbook, Yay Math

Notes:

If you are having problems with the textbook loading, first try reloading the page. If that doesn’t work, try a different browser.

When you score your answers to the review questions, always count up and record how many you got right. Don’t subtract the number wrong off the total given. Every problem is worth one point unless otherwise stated. You may grant partial credit for a multi-part problem.

Lesson 1(*) (Note that an asterisk * indicates that there is a worksheet on this lesson)

Welcome to your first day of school! I wanted to give you one important reminder before you begin. Many of your lessons below have an internet link for you to click on. When you go to the different internet pages for your lessons, please DO NOT click on anything else on that page except what the directions tell you to. DO NOT click on any advertisements or games. DO NOT click on anything that takes you to a different website. Just stay focused on your lesson and then close that window and you should be right back here for the next lesson. Okay?

  1. If you didn’t get here through My EP Assignments, I suggest you go there and create an account.
  2. (*) Print out your first quarter grading sheet or use the Excel version.
  3. What is geometry? Read the intro on the first page and then click on A and B. On each page, do the interactive activity.
  4. Complete part C, folding paper. Follow the directions. Click on “Constructions,” the first expandable section on that page, and go through the directions in C1 and C2. You don’t have to do the other sections, just this first part.
  5. Here’s an intro to the first topic, points, lines and planes. Remember that when we say something is 2D or 3D, the D stands for dimensional. A 2D object has two dimensions: height and width. A 3D object has three dimensions: height, width and depth.
  6. Read, do the review queue questions, check your answers at the bottom of the page, go through the examples and solutions carefully. Stop when you get to “Beyond the Basics.” 1.1 Geometry – Points, Lines, and Planes. (This site requires you to set up a free account.)
    NOTE – Answer Corrections:
    (Review Queue 3B is -3) Click and drag the blank space to see the answer.

STOP

Time for a report card and portfolio/records updating.

Portfolio/records: In your portfolio you should include a couple of your assignments from this quarter. You could also take a screen shot of the graphing calculator or other online activity. Choose things that are neat and well kept.

This is how you find your grade: add up all the grades you have been recording for this quarter. Add up your scores and write that number down.

Divide your score by total possible. Move the decimal point over two places to the right. In the next box over, write the number in front of the decimal (something between 1 and 100). This is your percent grade. In the next box over write your letter grade. Anything starting with a 9 is an A. Anything starting with an 8 is a B. Anything starting with a 7 is a C and so forth. If you have everything perfect, then your grade is 100. That’s an A too.

Your goal is to get an A for the course at the end of the year. Go back and look at where you lost points. What can you do to avoid losing those points in the next quarter?

Time for a report card and portfolio/records updating.

Portfolio/records: In your portfolio you should include a couple of your assignments from this quarter. You could also take a screen shot of the graphing calculator or other online activity. Choose things that are neat and well kept.

This is how you find your grade: add up all the grades you have been recording for this quarter. Add up your scores and write that number down.

Divide your score by total possible. Move the decimal point over two places to the right. In the next box over, write the number in front of the decimal (something between 1 and 100). This is your percent grade. In the next box over write your letter grade. Anything starting with a 9 is an A. Anything starting with an 8 is a B. Anything starting with a 7 is a C and so forth. If you have everything perfect, then your grade is 100. That’s an A too.

Your goal is to get an A for the course at the end of the year. Go back and look at where you lost points. What can you do to avoid losing those points in the next quarter?

Time for a report card and portfolio/records updating.

Portfolio/records: In your portfolio you should include a couple of your assignments from this quarter. You could also keep a page of notes from one of the videos with a note about what it is. Choose things that are neat and well kept.

This is how you find your grade: add up all the grades you have been recording for this quarter. Add up your scores and write that number down.

Divide your score by total possible. Move the decimal point over two places to the right. In the next box over, write the number in front of the decimal (something between 1 and 100). This is your percent grade. In the next box over write your letter grade. Anything starting with a 9 is an A. Anything starting with an 8 is a B. Anything starting with a 7 is a C and so forth. If you have everything perfect, then your grade is 100. That’s an A too.

Your goal is to get an A for the course at the end of the year. Go back and look at where you lost points. What can you do to avoid losing those points in the next quarter?

Time for a report card and portfolio/records updating. You will be finding out your total score this time by adding and dividing your totals from the four quarters. If you decide to, you could make up to half of your grade be for participation, completing the daily assignments. That would be 50 (for participation) plus half of your regular grade for your total grade for the year.
