Math Blog Post- The Triangle Inequality Theorem

The Triangle Inequality Theorem goes as follows:

“The sum of any two side lengths of a triangle is greater than third side length.”

This means that A and B must be greater than C. If it isn’t greater, then the triangle’s sides don’t match.

For example: A is equal to 4, B is equal to 3, and C is equal to 7.

This WOULD NOT be a complete triangle because 4+3=7. 

Let’s try another one: A is equal to 34, B is equal to 21, and C is equal to 50.

This WOULD be a complete triangle because 34+21=55, and 55 is more than 50.

Got it? Good!

 

 

Journal 11- Shabbos to the Elderly

Last Friday, sixth grade and a few eighth graders delivered Shabbos boxes to people. This is a project I created to give two candles, two homemade challahs, and a bottle of grape juice to give to elderly people in our community, so that they may perform the mitzvah of Shabbos. This is the second time we’ve done this this year. It is an act called gemilus chesed, or an act of kindness. It’s an act of kindness because we don’t need to do this; theoretically, if these people wanted to celebrate Shabbos, then they would’ve gotten these items by now. We do this for the people so that they don’t forget, or if they are too weak to go out.

SBC 7- My Day at School

For this week’s challenge, we have to talk about out school. Here’s the full list that was given:

  • Create polls about how people get to school or work, or favourite school subject or …..
  • What is your weekly timetable like, compare with other students – time you start and finish school, number of lessons each day, breaks during the day, days in year you go to school
  • Choices of subjects at school – remember to explain abbreviations you might use eg LOTE , ELA
  • Your dream of what you will be doing once you leave school
  • If you were principal for a week, what would you do? If you were a teacher for a week, what would you do?
  • Research the history of your school and create an about my school page
  • Research a famous person who attended your school
  • Technology in your school
  • What do you do at break times?
  • School bell has gone – what do you do now?
  • Food you eat at school – what is in your lunchbox or your school meal – good activity for taking photos
  • If you could improve your school, what would you do?
  • Your ideal school – maybe include a map of what it would look like
  • How has schooling changed over the last 100 years? Maybe interview parents, grandparents and ask questions about schooling – use soundcloud or audioboom then embed in blog
  • The view outside your classroom window – maybe explain plants that might be seen, the weather, seasons etc
  • Hold a debate about uniforms or school starting times or subjects or …..
  • Anything else that relates to schooling around the world

I will be telling what my day is like at school and answering a few of these questions. Read on!

P.S. I didn’t do the challenge last week because my blog, for some reason, won’t allow me to put on new widgets and the like.

6:30-7:00 (Eastern US Time) Wake up for school.

7:00-7:30 Get dressed, prepare schoolwork, etc.

Sometimes go to Chabad for morning services; if not, eat breakfast and go to school at 8:15. 

Praying in school– 8:15-9:00

First class- Mitzvot 9:00-9:38

Hebrew (Rosetta Stone)- 9:40-10:18

Tanach (Bible Studies)- 10:20-10:55

Hafsaka (Break)- 10:55-11:05

Language Arts (some of Eighth grade has Pre-Algebra now)- 11:05-11:50

Social Studies- 11:50-12:40

Science- 12:45-1:30

Lunch- 1:30-2:00

Geometry- (some of Eighth Grade have LA now, others have Algebra) 2:05-2:45

Physical Education- 2:55-3:40

School ends at 3:45

*On Tuesday, we don’t have a break and lunch is shorter so that way we can have a 25-minute Study Hall after lunch, so everything is moved up. Then we have Rotation instead of PE. Mine is Rock Band.*

After school, I will go to various Jewish classes, Boy Scouts, and basketball.

FACTS ABOUT THE MARTIN J. GOTTLIEB DAY SCHOOL

1. 53 years old, started off as a Solomon Schecter Day School.

2. Named after Martin J. Gottlieb in the early 2000’s, after Martin died of cancer.

3. Currently serves K-8, in the Galinsky Academy umbrella which includes DuBow Preschool, Makom Hebrew High, and Selevan Religious School.

4. Has about 120 students this year.

5. An Apple-based school, has 40 school laptops and 20 school IPads, with almost every classroom having a Smartboard.

To improve my school, I would have it start at 9:00 and end at 5:00, like the regular American work hours. I would have a study hall every day for 25 minutes and take away the break and 10 minutes from lunch, and 2 minutes from walking in between each class.  I would include PE on Mondays and Wednesdays, and rotation on Tuesdays and Thursdays. Friday I would keep it the same with the mitzvah trip and only secular studies.  Lastly, I would require everybody to get hot lunch.
