Measuring Angles with Protractors

We are finishing out our geometry unit by using protractors to determine the measurement of angles. We have really been having fun with protractors!






Here is a website that will walk you through the steps if you need a refresher: Use-a-Protractor

Kiddos will also need to be able to determine the degree without having a ray line up with the zero line. To do this, you need to skip count from one ray to the other to see the rotation degree. The angle below would measure at about 125 degrees.




They will also need to be able to draw an angle using a protractor.



Finding the missing angle is also a concept we have worked on. Angle COA is a straight angle and therefore measures 180 degrees. We know that angle BOA measures 44 degrees. We can subtract the known angle from the large angle to determine the missing angle (180 - 44 = 136). Angle COB would measure 136 degrees.



Here are some games where kiddos can practice using a protractor:

Homework this week will have students drawing angles to a given degree and reading a protractor to determine the degree. It will be due on 3/30. Please let me know if you have any questions!

Quadrilaterals and Triangles

We have been studying different geometric figures. Our main focus has been on classifying quadrilaterals and triangles.

A quadrilateral is a four-sided polygon with four angles. There are many kinds of quadrilaterals. The five most common types are the parallelogram, the rectangle, the square, the trapezoid, and the rhombus.

Here is how they relate to each other:

We have been looking at triangles based on their angles. 

The right triangle has one 90 degree angle and two acute (< 90 degree) angles.

Obtuse triangles have one angle that is greater than 90 degrees. Obtuse triangles have only one obtuse angle.

Acute triangles have NO angles greater than or equal to 90 degrees -- all their angles are less than 90 degrees. Acute triangles have three acute angles.

Homework this week will have kiddos classifying each of these geometric shapes. It will be due Monday March 23. Please let me know if you have any questions. Have a great week!

Auction Basket

A paper went home with your kiddo a few weeks ago regarding the Spring Carnival Silent Auction Baskets. The classes that bring in the highest bid on their basket will win a sonic drink for everyone! Our classes are putting together a "stationary" themed basket. We are asking for donations to fill our basket. So far, we have only had two items donated and are in need of more!

Please consider donating something to our "stationary" basket. Some donation ideas include notepads, pens, thank you notes, paper, stamps, envelopes, sticky notepads, labels, pencils, and stickers. We need all donations turned into us by April 1^st. Please let us know if you have any questions. Thank you!

Meet Mrs. Baker

Hello Parents!                                                                                                                  

I wanted to take the opportunity to introduce myself. My name is Stephanie Baker and I am a student teacher from Western Governors University. I will be joining Ms. Christian and Mrs. Milot in working with your child over the next 8 weeks or so. I am so excited to be at Cox and in 4^th grade!

I am getting my dual certification in Special Education and Elementary Education. My background is in Special ed; I worked as an instructional aide over the last five years and decided a couple years ago that I wanted to be a teacher. I absolutely enjoy children and am very passionate about the teaching profession.

I am married to a very supportive man and have a 9-year-old son, who is in the third grade. We stay busy with soccer, as I help coach his team. Go Shockers! We also have 3 adorable dogs that are very much a part of our family!

I’m very excited to see what the next few months have in store for us! Please let Ms. Christian or Mrs. Milot know of any questions or concerns you may have!

 

Thank you,

Angles

We have begun our geometry unit and the kiddos are loving it! We have learned all about angles so far.

An  angle  is the intersection of two rays with a common endpoint.

There are four types of angles that we have learned about.

An acute angle is an angle whose measure is less than 90°.

A right angle is an angle whose measure is 90°.

An obtuse angle is an angle whose measure is more than 90°,
                            but less than 180°.

A straight angle is an angle whose measure is 180°.


Remember that an angle is named using three letters, where the middle letter corresponds to the vertex of the angle.  The angle below is <ABC or <CBA.   If it is perfectly clear which angle is being named, an angle may be referred to by its vertex letter alone, such as <B.


Here is a fun website that allows you to play around with angles:

Homework this week will have kiddos identifying types of angles. Please let me know if you have any questions. Have a great week!

Elapsed Time

We have just finished out our unit on measurement. This included calculating elapsed time. Elapsed time is the time that elapses while some event is occurring. We learned a few different strategies to calculate this, including using a number line and a t-chart.

Here is an example of solving an elapsed time problem with regrouping of time:

Homework this week will have your kiddo practicing this skill. Please let me know if you have any questions. Have a great week!

Week of 2/16/15

We have a busy, busy week coming up! Here is a look at what we will be doing:

Monday 2/16- No School

Tuesday 2/17- Math Benchmark;

• This will be similar to the writing benchmark that Ms. Christian blogged about at the beginning of the month. It will be similar to the Math STAAR. I will use the data from this assessment to help guide me in reteaching, tutoring, and small group instruction. I want your kiddo to be as prepared as possible and this assessment will help me accomplish that. :)

Wednesday 2/18- Symphony Field Trip:

• Be sure to have your kiddo wear their "best" dress. It is SO much fun to see everyone dressed up! This will be a morning trip. We will be back in time for our regular lunch.

Thursday 2/19- Reading Benchmark

• This will help your kiddo and Ms. Christian prepare for the Reading STAAR.  

Friday 2/20- First regular day of the week! :)


Because this coming week is so hectic and the kiddos will be working so hard on the benchmark assessments, I am NOT assigning homework this week.

Please let me know if you have any questions or concerns! Have a great week!
