Fair trade – what’s it to you?

What do you think of when you hear the word “trading”?

International trade? Stock market trading? Trading one item for another? Perhaps a Trade Fair, or selling items at a market stall? Trading as your *business name*? Maybe you are committed to purchasing “Fair Trade” in support of the  World Fair Trade Organisation’s aim of making international trade more equitable?

As an early childhood teacher, I think of trading games that we use in maths lessons to help children understand place value. In our decimal system, we use ten digits in various combinations to represent numbers. Placement of each digit is vital; for example, 290 is very different from 902.

Without a firm understanding of place value, it is difficult to work with numbers efficiently. I believe that many difficulties with number stem from insufficient understanding of place value. Children need to experience numbers in a variety of contexts to fully understand the decimal system.

For younger children just beginning to learn about two-digit numbers, we may connect interlocking blocks or bundle popsticks to form groups of ten.

 

When children have a firm understanding of the grouping process, and the way the numbers are represented with two digits, they move to a similar process with numbers over one hundred. It is at this time that we introduce trading.

Instead of using interlocking cubes or other items that can be linked or bundled, ten individual cubes are traded for one ten, and ten tens are traded for a one hundred flat, and so on.

I feel so strongly about the importance of children learning place value, that I have made a variety of resources for teaching it. The resources, available from readilearn; include:

Beginning place value – the train game

Race to 99 – A place value game for maths groups

The interactive resources

Playing games has always been a favourite activity for me, and always popular for family gatherings. We’d quite often we’d spend holidays, like Christmas and Easter, when the children were growing up, playing board games or card games. One of our favourite games, especially if there were larger numbers of people (up to ten) was a trading game called “Billionaire”. It is a raucous game. Everyone is engaged all the time. Play involves trading cards (commodities) with each other, and this involves much shouting (over the top of each other) and laughter. If you have never played it, but enjoy games, and have a group of four or more to play, I highly recommend it. (Sorry, I couldn’t find it to add a photo. It’s hidden away in the games cupboard somewhere.)

I couldn’t write about trading without mentioning Jack and the Beanstalk. Mother sends Jack off to the market to sell the cow. Along the way, he meets a man with a handful of “magic” beans which he offers to trade for the cow. Not having heard the saying, if it sounds too good to be true, it probably is, Jack agrees. Of course, Mother is none too pleased and throws the seeds out the window. But, as the story shows, Jack was right to trade and rewarded for his ignorance of the oft-touted adage. (The story also raises other issues regarding trespass, theft, and causing fatal injuries. But we won’t go there this time.)

This week at the Carrot Ranch Charli Mills has challenged writers to In 99 words (no more, no less) write a story about trading. It can be the profession of old or of modern day traders on Wall Street. It can be trading places or lunches at school. What is traded? Is it a fair deal or a dupe? Trade away and go where the prompt leads you.

For my response I’ve ended up in the playground yet again. It involves a little trading of cards, but more a trading of power. I hope it works.

Trade fair

Cards, were coveted like gold. To belong, one was enough; more better. Each lunchtime the boys showed off new acquisitions, compared intelligence and strength points, and traded duplicates. Fair and friendly battles pitted minds, the winner claiming card supremacy. Then bully Boris won, and none dared challenge. Until Justin, tired of Boris’s tactics, dared.  The group gasped. It seemed Justin would be crushed. But clever cardless Frank slipped in and showed the winning move.  Boris growled, “Inadmissible” and threatened repercussions. Defiant, Justin handed Frank a card, bestowing membership. Empowered, each boy followed, declaring Frank the Master, and trading opened.
