Students Discover MIdpoint Formula

2010-09-13T16:11:00.000-07:00

In this activity students explored midpoints to discover the midpoint formula. Allowing the students to use various folds and measurement to figure out this formula on their own will help them to remember the formula and be able to apply it to real world situations.

Geometry Students Dive into Circles

2010-02-10T10:58:00.000-08:00

Geometry students use hands on activities to explore the geometry of circles. Students capitalize on their previous knowledge of regular polygons to explore the circle.

.

Throughout this unit on circles students will be learning:
* how radius, diameter and circumference are related
* what arcs can occur on a circle and how they are distinguished
* what relationship exists for inscribed angles and their respective intercepted arcs
* how lines that intersect circles are different or alike
* how to intersecting secants and tangents determine relationships for angles and segment lengths in circles

Creating Congruent Triangles

2009-11-04T16:22:00.000-08:00

The geometry classes started a new unit today about Congruent Triangles. The students discovered congruence in triangles by participating in a fun activity where they worked in pairs to create triangles according to specific angle or side measures. Then they placed their newly created triangles in categories. As a class they reflected on the different categories in order to discover difference congruence relationships between triangle parts to determine if in fact the triangles were congruent. Tomorrow the postulates and theorems that go with congruent triangles will be introduced. After completing this activity, learning the new postulates and theorems should be a breeze!

Geometry Students Discover Triangle Classification

2009-10-20T08:25:00.000-07:00

The Geometry students began a unit on triangles this week. They began by working in groups to make a concept map about triangles.

The students then presented their concept maps to the class for discussion.

Using a ruler and protractor the students measured 9 different triangles and completed a table with the side lengths and angle measures of those triangles. They used this table to answer questions about the classification of the triangles.

Students walked away from this lesson being able to accurately classify a triangle by its angles and sides.

Good afternoon, Here are your instructions for the day. Pick a group and sit down.

First check your homework using this key.

Next you will complete several puzzle proofs with your group. When you have completed your puzzle the substitute will check your answers. If it is correct, you will complete another proof puzzle. You will continue this until your group has completed 4 puzzles.

Then go to classzone to complete the Chapter 2 animation titled Write a Two Column Proof You may use your group for help completing this animation. Just complete the first proof

Finally, you may begin your homework which is in your geometry book.
Pg 116-119 (13,15,16,17.18,21-29,31)

Instructions for Wednesday p.m. classes 9-23-09

2009-09-22T15:48:00.000-07:00

Turn in your homework

Today you will need to fill in your vocabulary sheet by reading pages 96-98 in your geometry book and reading over these notes:

Then you need to visit classzone and complete the Chapter 2 Describing Patterns animation.

Finally, you may start on your homework:

See you tomorrow!

Instructions for Tuesday p.m. classes 9-8-09

2009-09-07T15:29:00.000-07:00

Hello Afternoon Classes,
Here are your instructions for the day:

First
Open your Geometry Notebook that you created in Word and add these vocabulary words to the vocabulary tab in your notebook

Then add these Postulates to the Postulate tab in your notebook

Then
Go to classzone

and complete the animation titled Chapter 1: Using a Protractor.
Next
Open your textbook to pages 24-28 and read. You will review acute, right, obtuse, and straight angles, and learn two new angle postulates.
Finally
Homework: pg 28-32 (1,2,4-6,9-18,21,44-48)
You will NOT need a protractor for #11-14, just classify the angles as acute, obtuse, right, or straight. You may use the graph paper at the front of the room for #44-47 if you would like. It is not required.

BE ON YOUR BEST BEHAVIOR. I will deal with any discipline problems tomorrow.

Welcome to Geometry

2009-08-22T20:07:00.000-07:00

Dear Students and Families,

Welcome to geometry! I’m excited about the opportunity to get to know you, and I’m looking forward to a happy and productive school year.

Curriculum areas we will focus on this year include an opportunity for students to develop reasoning and problem solving skills. Topics such as congruence and similarity of lines, triangles, quadrilaterals, and circles will be studied as well as use of length, perimeter, area, circumference, surface area, and volume to solve real-world problems.

Students are asked to bring the following supplies to school before Monday, August 31:
Pencils/NO PENS
Notebook paper
1” three ring Binder
Computer/Charger
Calculator

My homework policy is homework is due at the beginning of each class period and late work will not be accepted. One quiz grade and one daily work grade will be dropped each six weeks. Students are responsible for picking up their make-up work. Students have one day to complete make-up work for each day missed.

My grading policy is:
10% - Daily Work
(homework, class participation, etc…)
25% - Quizzes
(individual & group quizzes, pop quizzes, and quizzes over homework)
65% - Exams
(chapter tests, mid-chapter tests, & six week tests)

Studies show that parental involvement in a child’s education is one of the strongest indicators of student achievement. We hope you will make it a priority this year to attend as many school-sponsored events as possible.

If you have any questions or concerns or if you would like to visit our classroom, schedule a conference, or volunteer to help out, you can contact me at (work) 937-6131, (home) 937-3353, or email me at psteed@childressisd.net. The best times to reach me are before or after school or during my conference from 10:00-10:40 each day.

Once again, welcome to geometry. Let’s work together to make this the best year ever!

Sincerely,
Paige Steed
