Pandas by wanghonghx


									                     Let pandas go extinct!
                       There are only about 1 500 pandas left in the wild.
                  Around 150 live in zoos and breeding centres, mostly in China.

Up2d8 maths
Teacher’s guide
Towards the end of September 2009, two wildlife specialists
spoke about pandas. One felt it was time to let that species of
bear die out, and the other felt they needed continued
protection. This Up2d8 explores both arguments and
encourages the children to discuss their opinions. The ideas on
the spreads focus on number and calculation skills that can be
adapted for all ages.
You might find it helpful to explore the following websites:

1st spread: Pandas should be left to face extinction!
● Together read the numbers of pandas in the wild and in captivity. What is the difference
  between the two? Can they imagine how many 1 500 and 150 are? Explore the place
  value of both numbers, including the importance of zero as the place holder – without
  them the numbers would be the same: 15.

● Discuss what is meant by ‘in the wild’ and ‘breeding centres’. Which do they think is the
  best place for pandas and why? Encourage the children to give positive and negative
  views, eg. in the wild they might be hunted and in breeding centres they are protected, in
  the wild they are free to roam anywhere, and in breeding centres they are held in
  captivity and their movement is restricted.

● Lead a discussion on the views of the two people. How much is £1.5 million, is it a lot of
  money? Is it right to spend that much keeping an endangered species alive? What other
  ways could the money be spent that might be more useful?

● Do they think it matters that a lot of people donate money specifically for pandas?

● After some discussion, take a vote of their opinions: save the panda or let it die and
  display the results in a Carroll diagram or table.

● If someone earns £30 000 a year, how long would it take them to earn £1.5 million?
  Where do the children hear of that amount of money being won – in the lottery, ‘Who
  wants to be a millionaire?’

● You could set a task for the children to try to spend that amount of money.
1st spread: Pandas should be left to face extinction! continued…
● Discuss what is meant by ‘the rarest bear’ and endangered species. Ask them to think of
  other animals that are endangered and whether anything is being done to save them.
  You might find the WWF website useful.

● Also consider those animals that are now extinct, eg. the dodo. Is the world a
  worse/better place without it? Will people forget about the panda in time if it is left to
  become extinct?

● You could look at the third spread for further discussion points: arguments for and
  against the panda. Discuss each point, which do the children agree with?
2nd spread: Panda Facts…
● You could ask them to work with a partner and a large piece of paper and draw the
  outline of a panda within these dimensions.

● Look at the weight of the male panda: up to 250lbs. Discuss the units of measure and
  their equivalences including imperial to metric if appropriate and measuring equipment.
  Give them a calculator and ask them to convert 250lb into kilograms: 0.45 x 250 =
  112.5kg. Can they imagine how heavy that is? You could compare this to 112 kilogram
  bags of sugar or similar. Encourage them to work in small groups to weigh out fractions
  of this amount in books or something similar. How many will they need to weigh
  112.5kg? Gather these together.

● Repeat this for the weight of a female panda. Compare the weights of both.

● You could ask word problems, eg. if I had 20 books each weighing 5kg, would that be
  equivalent to the weight of a male panda? How do you know?

● Discuss the number of cubs a panda will have. For younger children put the numbers on
  a table and ask them to match these with the correct number of bears, from a collection
  of toy bears or similar.

● What if the female panda could reproduce for 20 years, how many cubs could she
  potentially give birth to?

● Base the weight of a cub on 3 ounces and convert to grams using this conversion:1oz =
  28g. Repeat for other amounts. This could be a good opportunity to work on the grid
  method for multiplication or partitioning.

● Share this information about the cubs: they do not open their eyes until they are six to
  eight weeks of age and are not mobile until three months. The cub is pink, hairless, and
  blind. You could give the children pages of a calendar and ask them to work out when
  the cub will open its eyes and also start to move from dates you give them.
2nd spread: Panda Facts, continued…
● If the cub is1/900th the size of the mother you could ask them how they could show this
  visually, eg. colour one square of a 30 by 30 grid on squared paper.

● Discuss the food a panda eats. How much is 99%? Work through percentages of
  different numbers, basing calculations on 10% and doubling / halving / x10 / ‚10 /
  addition / subtraction. Ask them to use what they find to make 99% of the different
  numbers, eg. 10% and 1%, then multiply each by 9 for 90% and 9% and finally add

● Convert 20 to 40 pounds into kg (0.45 x 20lb/40lb). Ask them to estimate and weigh
  different amounts within these parameters. Inform the children that the rest of the
  panda’s diet is made up of such things as small rodents and fish.

● Tell the children that much of the water the panda eats comes from bamboo. New
  bamboo shoots are about 90% water. They also get water from rivers and streams. The
  forests of central China where giant pandas live receive about 30 to 40 inches of rain
  and snow a year. Discuss capacity – vocabulary, units, measuring equipment. Ask them
  to estimate and measure the equivalent to 30, 32, 35 inches etc.

● Use the information that the panda spends 10 to 16 hours a day foraging and eating.
  Give starting times and ask them when they might stop eating.

● Repeat this for the sleeping time, firstly asking questions such as if they spend 14 hours
  a day foraging and eating, for how long do they sleep?

● Make up birth dates for pandas and ask the children to work out when they will die
  naturally (after 35 years).

● Use the sand area to create a panda reserve.
