Why Do Mathematics?

As a new high school teacher a couple of decades ago, my 15 year old students asked me (with all the dramatic tones of that age group) : “Why do we have to do maths?”f orbiting

My brain raced – we didn’t cover this at teacher’s college! Momentary panic. Deep breath. Quick prayer: “Give me a clue, God”.

My response was like this ::

I believe in a created order and in that order, there are patterns, sequences, cycles, relationships, and series. There is a rhythm to life. A coming and going. People and living things grow old and die, then there’s another cycle that brings new life and fruit.

There is a time for the sun to shine, then the moon. The moon goes from new to full moon every 27 days. The tides ebb and flow because of the gravitational interaction of the earth and the moon.

Look at the seasons. We can closely guess what weather to expect in August because there is a pattern throughout the years.

We can not get away from maths concepts.

We use maths to get to our friend’s house, buy food and clothes, to decide if we can cross the road so as not to get run over by the bus coming, to get ready for the party on time.

So, why do maths?

1. Because the school says so.

2. Maths Certificate tells employers you can multiply and add and a bit more.

3. More importantly, maths teaches you to solve problems, follow logic, find relationships between number-based ideas, and to make real-world decisions based on known and unknown information or data.

4. It;s fascinating.

Let’s start being number detectives. 😀

Occupations ::
There are uses of mathematics in all the “hard” sciences, such as biology, chemistry, and physics; the “soft” sciences, such as economics, psychology, and sociology; engineering fields, such as civil, mechanical, and industrial engineering; and technological fields such as computers, rockets, and communications. There are even uses in the arts, such as sculpture, drawing, and music. In addition, anything which uses a computer uses mathematics,

Mathematics is used for biomedical engineering, food technology, building technology, chemical sciences, civil and structural engineering, graphics and computer-aided drawing (CAD), electronics, environmental health, mechanical engineering, mining technology, nuclear medicine, occupational health, petroleum technology, prosthetics, forestry and wildlife, robotics, and surveying. it is used in so many other subjects.

National Association of School Lunches Takes Aim at Those Who Dare to Eat at Home

by Valorie Delp

The National Association of School Lunches today, in a bold public statement, expressed their concern over untrained mothers serving lunch to their children. Says one source, “The problem is wide spread. We have mothers, who are untrained in how to serve lunches, feeding their children, in their homes. Something simply has to be done.”

The National Association of School Lunches warns parents of the possible ramifications of feeding their children at home: Children will be deprived of the social experience of eating in the cafeteria. Some important social rites of passage, such as food fights, will be completely skipped.

Students who eat at home may not get to learn how others students in other parts of the world eat. Exposure to chopsticks or eating on the floor will be completely diminished.

Students who eat at home may not get the full range of foods that are available only through the school cafeteria.

There is no quantifiable way to measure the nutritional standard of the food being served. Surely parents need to be told what foods their children must eat. Lunch eating is serious–moms could never figure this out on their own.

But the biggest argument put forth by the National Association of School Lunches is that mothers are untrained in serving lunches. They strongly feel that in order to serve school lunches, one must have taken important courses and be certified in things like serving techniques, placing the food properly on the tray, anti food-fight tactical manoeuvres and how to dollop mush. Although mothers serve their children lunches every day from birth until that child enters school, once the child is school-aged, the parent must be trained or their lack of training could be a detriment. Previous experience counts for nothing in the hard core, fast paced world of school lunch serving.

Another key concern are health and safety standards that are required by law in school cafeterias. Although I cannot explain how the phenomenon might occur, apparently home is clean enough for breakfast and dinner but during the lunch hour, homes everywhere must be attacked by germs and bacteria thus necessitating state produced standards for cleanliness for the lunch hour.

Finally, school lunch personnel everywhere are concerned about accountability. Should children have to prove that they’re getting adequate nutrition or perhaps should mothers have to submit meal plans for the year to be approved by the state department of school lunches to check and make sure that the food that’s going to be served meets nutritional standards.

Come back later as I have a feeling that there might be more from the National Association of School Lunches.

More Time Now I’m Off Facebook?

So, I’ve just deleted the Bookmark button to Facebook and will try to stay away from there until December 1.

I hope I do better than the Milk-Free Week I tried a few weeks ago. In that case, I did become more mindful of the huge number of things I eat with milk products in them! I failed more than once but did not give up trying until the week was out.

I have Pinterest (less time-consuming and it raises my spirit with beauty and creativity) and a couple of WordPress accounts – it’s not like I’m going cold turkey off the internet.

Here’s some videos that helped to bring about this change:

As with all addictions, I need to consciously plan to change habits and to use time more constructively.

What comes to my mind?

  • play board games with my children more than one night a week,
  • read more,
  • meditate on God’s Word (Bible),
  • chat with my husband before 10 pm,
  • deep clean my room,
  • socialise with friends,
  • type up recipes and update recipe book.

… got any other ideas?

URGENT : spelling/grammar lesson

Here’s your spelling lesson for today.

All bloggers & writers, please note :

  • Plurals do not need apostrophes.
  • Apostrophes are usually used when a letter is missing.
    eg. you’re = you are.   ‘You’re welcome to come to the party’.
    Not to be confused with ‘your’ = belonging to you, eg. your hat.
    It’s = it is. Its = belonging to it.
  • definitely – distinctly, precisely, clearly.
    There is definitely no ‘a’ in ‘definitely’!
    Please don’t confuse with ‘defiantly’ = aggressively hostile.
  • voilà = French for ‘here’. Opposite of ‘voici’.
    Not to be confused with ‘viola’ = a larger-than-violin musical instrument, or a small violet flower.

‘Tis enough for now. I’m sure there’s many more creatively spelled words that are rampant online.

It’s been a while …

An upgrade to my computer means that I once again can interact with my WordPress blogs.

I actually wandered into Facebook and Farmville and Country Life … for a couple of years. It was fun for a while. I met some nice people around the world along the way. But the literacy level of too many FB users is low and reading posts was for the most part mind-numbingly, well, numbing! Not to mention the irritation of people who don’t know your from you’re. Or its from it’s.

I’ve read some interesting thoughts on homeschooling, church drop-outs, parenting skills. I fiddled with apps that allowed me to make a “movie”, enter competitions ( I won two lots of chocolate and movie tickets), and play more zombie games.

But I needed to subscribe to two WordPress blogs recently and a much more interesting world opened up to me again. And I’ve re-met some ‘old friends’ in the form of elegantly written blogs.

This week:
