Financial math for kids in grocery shopping



苹果 by Elizabeth

Grocery shopping can be a fun, practical and time saving activity for teaching children financial math and economics besides food and nutrition while getting the chore done.

  • Reading grocery store ads are family math time for us.  We discussed things like:
  • How to compare prices (price per unit)
  • Why we should buy things on sale as much as possible?
  • Why most items are priced with numbers that end with .99, e.g.3.99

Many Uses of 心

The following is from a Chinese school principal’s page:

Student’s Concentration       上課專心

Parent’s Participation            家長關心

Teacher’s Devotion                 老師苦心

Pupil’s Attention                     讀書用心

Volunteer’s Dedication         義工熱心

Children’s Companion          兒女貼心

Everyone’s Gratification      大家開心

The last character of each phrase above is “心”, which means “heart” in Chinese.   It is interesting that none of them says “brain”.    While any one of the above requires serious brain effect, it is the satisfaction of the heart is the primary goal.    Who is to say that the higher the emotion the lower the brain?

Life is but a dream

What happens to websites if computers are down?  Computers, I mean, include iphones and tablets.   Then all that many have built would be gone for good, possibly.

If my website is gone, then I have nothing to say but “life is but a dream.”

To my dear daughters

Yes, it is your mommy’s own fault that she bought you all these books with pictures of princesses conveniently at supermarkets.  She calls you “my little princesses”, and, at the same time, she tells you that the movies or pictures of princess are going to make you stupid.  Yes, she is having a hard time making up her mind.

Every mother wants the best for her children.  Whatever the original version was, I have changed the story of Cinderella to the following for you:

Because Cinderella works hard and keeps her dream alive regardless her circumstances, she receives the help from a goddess, who helps Cinderella to make her dream come true.  If Cinderella were to be lazy and vain like her two stepsisters, her dream would not have come true.  

You asked me “Mom, when will the goddess come to help us and make me become a Cinderella?”

I replied “You have to work, study (especially math and mandarin Chinese) and play like you did today everyday.  Then your dream will come true.”
