Tuesday April 24, 2012

This week we will be finishing up our final week of the cirriculum by looking at probability. Begining next week we will be splitting into small groups where every day students will be at a different station in preparation for the EOG test.

Here is what we are looking at this week

Monday- Experimental Probability: Performing an experiment to find out how likely an event is to occur

Tuesday- Tree Diagrams and Fundamental Counting Principle: Drawing a tree diagram to see all the possible outcomes of an event.

Wednesday- Compound events: What are the chances that one event happens as well as another event (chances of rolling a 1 then a 5)

Thursday- Dependent and Independent probability: Occurance of one event does or does not have an effect on the second event happening

Friday- Permutations and Combinations: An arrangement in which order is or is not important.


Since we are not spending a lot of time on probability, there will likely be a homework assignment nearly every night this week. Assignments are not long nor difficult, but students need to spend the time to get them completed so they get the extra practice they need. As always, please email me with any questions/ concerns you may have. nathan.culp@nhcs.net

Sample Quiz questions for Friday's quiz

Tomorrows quiz will include questions very similar to the following...


A circle has a radius of 4 cm, find the diameter, circumference, and area


Answers:
radius = 4cm
diameter = 8cm
Circumference = 25.12 cm
Area = 50.24 square cm


A triangle has angles of 90, 30, and "x". What is the value of x?

Answer: 60 degrees (every triangle has a total of 180 degrees)


What angle is supplementary to an angle of 60 degrees?

Answer: 120 degrees (supplementary angles have a sum of 180 degrees)


What angle is complementary to an angle of 30 degrees?

Answer: 60 degrees (supplementary angles have a sum of 90 degrees)


There will be a question that requires finding the perimeter and area of an irregular polygon (we did a worksheet on this in class today)


If students feel comfortable with the homework assignment from today, they will have no problem with the quiz tomorrow. We will take the first 15-20 minutes of class to go over the homework assignment before taking the quiz.

Here are the solutions to todays homework

1.) r = 6cm d = 12cm C = 37.68cm A = 113.04 sq cm

2.) r = 9m d = 19m C = 59.66m A = 254.34 sq cm

3.) 50 degrees (supplementary angles)

4.) 50 degrees (sum of a triangle is 180 degrees)

5.) 60 degrees (sum of a triangle is 180 degrees)

6.) Segment EF (parallel lines)

7.) Segment EA or FD (perpendicular lines)

8.) right triangle or scalene triangle

9.) P = 40 cm A = 60 sq cm

10.) P = 34 m A = 36 sq m

Wednesday April 18, 2012

This week we will continue to focus on geometry.

Monday - Types of angles and lines (no homework)

Tuesday - Triangle properties (homework: page 67 in math workbook)

Wednesday - Perimeter of irregular shapes (homework: page 80 in workbook)

Thursday - Area of irregular shapes (homework: worksheet)

Friday - Quiz on circles, lines, angles, triangles, perimeter or irregular shapes and area of irregular shapes

I will post sample quiz questions before Friday

Also, report cards should have gone home with students on Monday. I will continue to encourage students to stay focused and do their best to improve during the fourth quarter.

Today was our final day of our end of quarter 3 benchmark assessment. Based on what I saw while observing students work, it looks like most were selecting a lot of correct answers.

Tomorrow, we will be back to classwork where we will cover how to find the area of a circle. There will be a workbook homework assignment over the weekend.

The formula we will use to find the area of a circle is: pi x radius^2

When students return next week, we will be looking into some geometric concepts (we are not spending a lot of time on these because many are review from 4th and 5th grade).

Monday - parallel lines and angles

Tuesday - triangles

Wednesday - Perimeter of composite shapes

Thursday - Area of composite shapes

Friday - Quiz over circles, angles, and triangles

I hope everyone enjoyed their spring break! I think it was a much needed rest for students and hopefully they come back ready to finish the year strong!

We are down to our final 3 weeks of instruction before we begin station work to prepare for the EOG exams. In the next 3 weeks, we will focus on properties of circles, types of angles, ratios, and rates of change.

This week we are getting into properties of circles. Today we introduced a few vocabulary terms and practiced a couple of examples of each. Tomorrow we will continue practicing these terms and focus on finding the circumference of different circles. Below are the vocabulary terms from today

Center

Chord

Radius

Diameter

Circumference and formula to find circumference

Pi
